Thank you so much for this video. I just had a call from office staff re problems getting the computer to turn on. Rather than driving across town, calling a technician, etc., I walked them through this on the phone. It worked!
Thanks and happy it was helpful.
An excellent, step-by-step fault-finding video. Admittedly slow and tedious but that is the nature of successful trouble shooting. Well done
i had sooo many questions when i started this video bc i have an hp x360 doin the same thing, u went into great detail step by step and diagnosed the cause. u did awesome. i honestly have no questions at this point. AND THATS INSANE BC I OVERTHINK EVERYTHING!!!! im going to go try this now , fingers crossed , thanx in advance
Thank you! This video was really useful for me to get my laptop back up and running. A couple of months back I doubled the RAM in my Asus laptop and it was working fine until a couple of days ago when it wouldn't power on although the (relatively new) battery was clearly working. When I'd try to switch the laptop on the battery LCD and power LCD would come on for 1 second and then both would switch off. After replacing the FFC to the power button (because the old one looked terrible) that didn't fix the problem. After watching your video I removed everything one by one like you did to identify the root of the problem, and it was the new RAM that was causing an issue. I now have a fully functioning laptop and I can now try to work out why the new RAM was a problem. Really appreciated this video. You saved me having to buy a new laptop.
I'll bet most of you haters have never made a video for RUclips. Yes it was slow, but he explained everything he was doing. I've watched others that didn't take much time but also explained nothing. Thank you for an excellent video!
Thank you, I really appreciate the overwhelming response from my viewers, most of the comments I get on my videos are amazing, people that were able to get the computers working when they really needed them. I think more than 95% of the comments I have received have been positive. I appreciate each and every one of them, Including this one. "I almost did a time-lapse video with loud techno music on the background" Na, just kidding that would not have helped. :-)
Well, if they really didn't like it, they should demand a refund.
I appreciate the step by step you used in this video. I have had 2 different Toshiba laptops that have had the very similar problems. There were sporatic too. I do have experience with computers, laptops and education with electronics. But the laptop seemed so mystacal that my experince with them was challenging. But I want to have the confidence that you showed in this video. One of the Toshiba's that I still have expericed this problem. No video on start up. This has happened a couple times before. Today after I watched your video, I feel I know the culprit. I went back to the laptop, jiggled that connection (I have a wireless mouse connected to it) and pressed the start button and on came the laptop. I know I should trouble shoot to be sure and I will when time allows me. But thank you for giving me direction and more confidence.
i loved your teaching,detailed,simple,easy to understand and step by step approach,thanks
Thank you, I really appreciate those words.
Most technicians on big computer repair companies will tell the customer is a bad motherboard, you covered every possible angle, you are a true technician , Good video. Thank You for sharing your skills
i fix my own now i dont lagg nothing like that im glad i fix it on my own cos then i have to pay over 100 $ or more but i just press any bottoms so i just press FN AND F2 I THINK but then u turn it back on that how i did mine idk i got acer aspire v5
Thank you very much, but I have been doing this as a hobby, and the little I have learned with it I like to share with others. Thank you again.
@carpio01 i took the battery off it still working like that i dont need no battery 😁😊😊 maybe i need new one not sure thank u for this video im glad i found this video i was looking like 10 videos about this nobody was perfect but u are perfect thank u so much i didnt replace nothing i just took the battery off that it i turn it back on it works for me like that
That's because these type of repairs are not worth their time. They will tell the customer it will cost a minimum of $150 to fix plus parts if needed, and the customers starts to whine that's its too much.
Cry me a river, if you aren't technical enough to fix it yourself, you will need to pay someone or buy a new laptop
I grew a beard while watching this video.
I planted a kidney bean in a plastic cup like we did in 1st grade and it sprouted half way through the video!
My wife had 3 babies still no fix on this crappy lappy, wait 4 is coming!
Perfectic people it's a good video no one has anything nice to say anymore
Seriously Jesus forgive me Lord for taking your name in vain I could have went out and bought a new fucking computer
😂😅👍
So USB ports can make the whole unit unresponsive? That is incredible. You learn something new every day.
yep I had this issue with a neighbours netbook . before me it went to someone who was supposed to be ace with repairing laptops. input him to shame as he was giving it the big I am lol. but yes it also pays you to check the ports for visual damage or also a faulty usb drive can cause this as well
Very Good Movie! Thank You Sir. Very Good At explaining Everything! Nice and Slow And You Show Us STEP BY STEP! GREAT VIDEO! GOD BLESS YOUR SOUL!
Wow, thank you for this video! My computer stopped on me last week and today, after unplugging and plugging back in the RAM, the computer turned on again!
Thank you for saving me a trip to the computer repair shop!
I watched the whole thing. I needed to see something like this. It was the usb that did it. amazing.
Thank you, yes in deed the USB board in my case was the issue.
I ithow to test a cdi
Checked the voltage and wasn’t getting 19V until I started moving the cable around on my laptop. The 19V kept coming in and out and then I noticed some fraying on the cable inside the laptop. Positioned the cable to where I was getting a solid 19V and then plugged it in and boom. Charge light came on and got a replacement part on the way. Thanks to this video.
Thanks! It was the little USB/Audio board for me, it must have been shorting something out.
Thank you sir for showing the process of elimination on repairing. I have a L645 with the same problem. I thought it was just it was a bad power jack but now I will check out the switch and USB port board.
My goodness thank you sir. It was the screen that was shorting the board for my friend's laptop.
Thank you sir....You are a god among gods. I have had a Toshiba laptop that has not worked for over a year and was about to give up when I saw your video. I determined from watching this that my power button (ribbon cable) was bad.
Keep up the good work and thanks again!

Dude you are awesome!! I know your video is like 6 years ago but figured the same issue out. Ended up replacing the entire motherboard as it wasn't a usb issue. Thanks sooo much
Lol *hugs virtually*
7 years later and still useful. saved my life. was not willing to spend $2000 for another laptop
try taking the memory out and put only one of the two cards and try to turn the computer on, if the problem continues try taking that memory card out and put the one you had disconnected. This is done in order to check that the memory cards are functioning correctly. Keep track of which memory card you put in, if the monitor happens to turn on with one and not with the other then the memory might be bad. Try that and let us know if it fixes anything.
My laptop power button slowly stopped working and when I opened my laptop the ribbon was some how ripped so I had to order a new ribbon, but everything works fine! Thanks man you a laptop life saver!
you are the best online teacher.Thank you alot.
Thanks for taking us through the troubleshooting steps by step slowly like this. I sure it will help a lot of people.
If the usb board was the problem why it wont turn on while u disconnect the ribbon from board.
I worked and taught maintenance for 40 years. The one thing that I found that people were poorest at was troubleshooting procedure. All troubleshooting should start with a thought process of what procedure to use to eliminate non-faults.
In every situation, it is different, it could be a capacitor, or a ram stick that it shorts everything, even the hard drive is the suspect
Excellent fault finding procedure. Strip back to bare bones then one by one replace stuff. Gives me a route now through my faulty Toshiba Laptop Pro with same problem.
cool, were you able to fix it?
This is very informative, specially, the systematic diagnosis that walks you through everything that could have gone wrong. Thank you sir!
Dude.. all I have to say is I love you and god bless you. Had this same exact issue . Looked for hours for a solution , found your video. Tried everything you did and now my computer is fixed . 😁😁😁😁
Thank you, I am really glad that it helped you.
Please folks, don't try this at home until you try a simpler fix without opening up your computer.Remove the power supply, remove the battery, turn the laptop back over and press the power button to disapate any static and power from the capacitors. Turn the laptop back over and put the battery back in and plug the power cord in, turn it back over and turn on your laptop.This works 90% of the time, if it doesn't, just remove the battery and try with just the power supply in and no battery. If that doesn't work, take it to a 'reputable' repair shop, one that is recommended by someone you know who has had a successful and reasonably priced repair done on their own laptop. One more thing, please do not work on anything still plugged into the power unless you know EXACTLY what you are doing, that's one way to kill a laptop for sure without realising it.
Elaine yours seems to be the best advice I got on the net. I have an old ACER F5RL series. The notebook was standing for about 5 months, not turned on. (I work with MAC now...) so, of course, the accumulator was flat. on the front the yellow light and after charging, also the green light was working. left the charger on all night. yellow light is gone. only the green light is on. but does not start. I do not use the notebook for anything, just watch videos that my MAC will not play. The charger is on now, green light there is on as well. but it is cold. should be at least a little warm. even after only 5 minutes work. the green light on the notebook is on.
tried to take out the battery and work on mains only, nothing.
reset with a pin, nothing.
suppose it will be off to the repair shop and see how much they will charge.
first though I will lokk for abohter charger, though i do not htink he is the problem?
have a good day...
This is a beautiful lesson on trouble shooting and following the flow of power from the wall to each component. IF this video doesn't help you, it is either your CPU, motherboard, or hard drive. But from my experience if your hard drive is the problem usually the computer will boot to bios. Great work, I learned something new.. 👍👍👍
Thank you for your words and for watching.
Honest vídeo, fellow technitian. Thumbs UP.
Was about to order a motherboard.. I followed this procedure on a Toshiba Satellite C855-s5343 - Ended up being a short in the monitor connector... Thank You!!!
Cool, that is awesome. Looks like you saved some $. I was also thinking that the problem with this computer was the motherboard but I was so happy when it turned out to be something much cheaper and easy to fix.
I saw the problem as soon as you open the memory slots. Cheers
the memory wasn't seated properly
Great video to understand how to take apart and put together a laptop. I appreciated the easy going manner of the author, and the way you stepped audibly through your thought process (helps to have it together before doing the video - LOL!). My daughter's Toshiba would not charge. Went through the basic stuff of battery, power adapter and power jack to make sure power was getting to the motherboard. Stripped it down to the motherboard, checking every connection then put it back together (no left over screws!) and it now charges normally and is working well. Must have been a loose or dirty connection, I guess. Nice to have this video on the web to reference if I have to do this again ever. Looking forward to other videos you will do!
+rotocrate Thank you and I am happy that you were able to solve the problem you were having.
Post a video, or fix a talkative friend’s problem... suddenly you are crushed with “friends” wanting free troubleshooting & fixes.. computers...tv’s...autos...plumbing...been there, done it, but now using “tough love”... no more “freebies”.
Don’t ruin a friendship or acquaintance by being cheap. Taking a financial ‘hit’ on our part too often only lasts
so long. At least up front, offer some money, or baked goods, or dog walking (you get the idea) if low on cash to help you out. It WILL be appreciated & keep the friendship door open.
I hope that helps....
Thanks a lot! I tried the same dissection with my Satellite U40-t and checked one hour later that the SSD was not working. I released and reconnected it and it worked again.
Again... thanks!
Perfect, and thanks for watching.
same laptop,its only charging and it wont turn on also..help me!!
Thank you. I will show this to my students to show them what it means to trouble shoot. It is hard but rewarding work.
Thank you very much..
cant believe you ordered another 19v supply WITHOUT CHECKING VOLTAGES OF THE ORIGINAL ONE... OYYYVAY MAN
Thanks a million! I followed your logical approach and had success, even if the laptop is different from yours. The deported USB module was at fault.
Outstanding video!!!
really good video to show how to troubleshooot a laptop - exactly what I was looking for.
i am wondering why u didnt test the existing charger before buying a new one on ebay. wudnt that be a simply voltage check with a meter? i hope not to offend. i just want to be sure i didnt miss something.
After a month of worrying I finally thought I should just try to fix my ASUS K53SV by myself, since I wrecked it in the first place when I was trying to clean out the fan. Now my laptop is up and running again thanks to you :D. The power ribbon wasn't properly connected, fixed it up with some tape and blu tac. I thought I was cursed at repairing computers, but now I am invincible XD. Thanks for the tips and knowledge buddy.
My toshiba seems to have power the light comes on and optical drive, hard drive and fan seem to activate but laptop won't boot up and screen isn't coming on.
I got the same problem with a hp
ucity metalhead same
wait hey quell
jk
Check RAM, if it is working then it might be GPU. Do you hear any sound from windows booting?
Thankyou so much for your video, i opened the memory and put it back and the laptop turned on. You are a saviour!!
Thanks for watching the video and I am happy that it was an easy fix for you. :-)
My laptop is working but no screen and the hdd light is not blinking.. Is it the cmos battery?
Very, very informative video. Its hard to find useful videos on RUclips. This is definitely one of them. Thanks for posting!
Hey hi,
I wanna ask something about laptop,
Is it possible to make diy charger for laptop? I have an old laptop and the charger is missing and im just a poor guy who cant afford a charger, can you help me?
Hope you read this. :)

Great video and step by step guidance. My issue was similar to what was shown and I still cannot start my system. The fan does not turn but all the lights come on. I will now work on the fan and cooling mechanism.
mine turns on but the screen is black and it switches off right after help please :((
btw it's hp
Mine does the same thing.
Mine is a Dell inspiron
you're a GENIUS! I never knew you could trouble shoot by removing one device at a time - just like trouble shooting a car that won't start! I just went through the devices of my HP Pavillion (which was showing a power light, but wouldn't turn on) and off all the things it turned out that the DVD drive was the problem. I'll order a new one. You've just saved me £££ in repair fees - I wish I could buy you a pint :o)
I'm glad that it helped you, that was the primary reason that I uploaded this video, to help people. And you can share this video with your friends that have similar problems with their computer, maybe it could help one of them as well. Thank you.
"messed-up"....well I can see this is not going to be very technical.
"bought another power adapter because no way to check it"- no multimeter?
is this even worth watching?...
thanks just followed your instructions and was able to fix a problem with usb reader board/ribbon to solve my power issue.
GREAT JOB EXCELLENT TEACHER THANKS A BUNCH FIR ALL OF YOUR TIMR AND EFFORT
Great video for troubleshooting power. Thank you, and this confirmed my suspicions with the USB on the exact same model a customer dropped off in my shop!
My Laptops lights turn on briefly and so does the fan. However, it shuts of just as fast Can someone tell me what the problem is and how to fix it. Thank you Joe
Same prob !!
Same problem here
very nice. very thorough. Thank you for posting....I have a Toshiba that "died" some months ago. I'm going to see if I can follow your trouble shooting procedure and fix it, or at least discover the problem. Thank you again for posting this helpful video.
worst dead laptop diagnosis ever. i dont know if ac adapter is bad ..well use a freakin multimeter instead of buying a new one. Same with power button it shoud get 3 volts at ground and button that means is ok, then go to next step.
cos cos bobo Thanks for watching! Yea If you have the tools and knowledge sure test the 19v, 3.3v, 5v as well as all the enable signals. But this tutorial is meant to be simple. Just because you assumed it was meant to be full in depth does not mean it is "the worst... ever" it is aimed at someone who does not nesesarily have the tools. The majority of coments are possitive, about how it helped them fix a computer without taking it to a repair place. And 3.3v at power button does not nesesarily mean it is good. If the title of the video was advanced motherboard component repair it would be different. Thank you for watching though, and I would really appreciate less negativity on the comments section. Thank you.
@@carpio01 if you can afford parts you do not need you can afford a multi-meter. Further more if one lacks the knowledge to use a multi-meter than maybe they should not be tearing into a laptop. Leave it to a tech not a parts replacer to have it fixed right. Especially with electronics where exchanges or refunds are rare. I'm not going to say this is the worst ever, it's obvious you love to work on computers and I don't want to discourage you. As someone who has been in your shoes in the beginning of my career as an auto tech and then later as a PC tech here is some advice. You are going to cross paths with many techs that are better and more knowledgeable at their trade. Especially Prima Donnas who will brag and boast and stroke there own egos. The important thing is to set your own ego aside and learn from them. Pick their brains. Most important is never get to the point where you think you know it all. Always be learning new things. "No it alls" stop learning. Thank the ones who took the time to teach and teach the ones that are eager to know. Good luck and have a nice day.
@@charlesmagliocco8932 This is a video tutorial for beginners, why can't you people understand that? WTF are you doing here btw?
@@jan-janlofranco1465 Very simple, for him beginners need to keep hands away, ONLY EXPERTS
@@carpio01 Aimed at someone who may not have the tools? It that why your dumb ass was poking with a metal screw driver to how how a dumbass changes shit until something works...From the video you still dont have a clue what you did what was wrong or even what to call anything....Never heard of a daughter board ...And you say memory but didnt even mention Ram ...Hel you didnt even know what to call a Power supply ... Your damn lucky you was working on a laptop cause you will shove that screw driver in the wrong place one day. And another thing if your so professional why didnt you mention static electricy from a discharge from your body can fry electronics ...Ever heard of a wrist strap for grounding dumbass? gtf outa here
Your nothing but a part changer...You couldnt diagnose a fucking Toaster!
Thanks so much, very well done and useful. It helped me to find the USB cable that was causing no power to come for my Lenovo G505 laptop. Disconnecting it made the power work again!
Thanks for watching and I am glad it helped.
that's pretty much awesome, i am also gonna try this at my toshiba laptop having same problem not powering on.
My guess is you guessed the USB board was bad and got lucky. Otherwise, how would you have known it was the USB board causing the PC not to turn on? You got lucky dude and you know you did LOL
While I was watching your video I decided to pull out items, memory, cd rom etc and it came on. After troubleshooting I discovered it was the cd drive was bad and the computer came on. Thank you
BTW Great video
hey everyone listens I was also facing the same issue...it cost me 2000 rs in repairing shop...you just need to open ur laptop and on the green board there will be a chip of black colour...you just need to clean that with the help of petrol ...that's it
Good job Sr. Thanks for the video. I did a screen replace on a Dell laptop, and know having a problem with the power Jack. You have shown me everything I need to do to fix it.. Thanks a lot..keep up the good work
My laptop was not turning on and also my adapter was blinking then
I tried mentioned methods in lenovo forums
I removed battery, removed Cmos connector, then held power button for one minute and then without connecting battery provided a direct power to laptop, it blinked for
But it blinked for a second and then went dead. Then on youtube a guy showed a step "to remove keyboard connector flex and then turning it on by novo switch and it worked. So now keyboard is dead but laptop is working. Is there any way to solve the issue
Kindly help
Bro we have the same problem
But i didn't try the keyboard
@@kxnt2374 try it , remove the connection between keyboard and motherboard and start the laptop through NOVO button otherwise service center will say that your motherboard has issues and will make you pay alot
@@rajatthakur9091 yeah i want to do that but i don't have tools and im not that good when it comes to laptops
@@rajatthakur9091 the service center charges me $80. They say the power supply is broken
thank you so much for answering my question. I had to replace the motherboard and all is now OK. Ordered it from Alibaba in China and they were so very helpful & reasonable.
+Eddie Dalton glad its working now, thank you.
Your A FUCKING LEGEND I LOVE YOU
Thanks for watching. Hope it helped.
I was working on an asus with the same issue. After process of elimination and literally at the exact same time you discovered the problem with yours, i pinpointed my issue... it was the exact same problem caused by the exact same part.
nice one man
Thank you for watching.
Thanks man. Best Laptop trouble shooting video I've seen in a while.. Simple and you could follow this procedure with most laptops in a similar way.

Very methodical, Nice video!
I have to do this time to time for my customers and mainly it ends up being a faulty power adapter or a faulty power jack/socket.
Rarely it turns out to be a power button or a broken usb socket that they jammed a USB device into incorrectly and shorted two pins with the force. Trick is to look into the socket with a flashlight for the four gold pins and if they are all level and shine fairly equally and the plastic tab is still there then the socket is OK. Once you are inside a laptop like carpio01 demonstrates above, you can always take a multimeter to the individual pins of the USB sockets to test for shorts.

+Godofredo Torres thank you.
Great post, I have the same problem with my Tosh l655, and thanks to you I have found the solution to the problem.
Thanks for posting this very helpful video.
Thank you for this video - very helpful, and I really appreciate you walking through all the steps to explain things logically.
Great video !!
Followed your steps for troubleshooting and managed to fix a Toshiba Satellite L45
Thanks !
Hello...great video thank You. I followed your advice and traced the fault to a broken connection(black wire) on the power connector - the laptop had been dropped and the solder connection had broken on the end opposite where the 19v should be. I noticed that the 19v was intermittent in the windows and then discovered that the connection was hanging on by a single thread of solder...a quick fix with a soldering iron:-)
Thanks for watching and feedback it makes me happy knowing that you were able to find the fault.
We were trying to find tutorials to fix our laptop, but then we realised the Power Adaptor wasn't on. This video was helpful though!! x,D
Good job and you are very good analyste and teacher 👍🏼
Good use of a step-by-step trouble-shooting procedure.
Thank you, I try to explain in a way that I would understand.
omg thank god for your video. i think i might have solved my own laptop problem. going to open my laptop and unplug the usb board. I was charigng my laptop and charging an very old ipod when my comptuer suddenly crashed. Maybe the ipod cable cause my usb board to burn up. thanks for this video. i love the logic of how you went through each part. i am very familiar with testing a desktop comp but never with a laptop. this showed me everything i need.
this is great step by step tutorial of repairing a laptop, thanks so much
That was the best and most informative you tube video I ever watched thanks man you taught me so much about computers :-)
Thank you very much.
Honestly, I'm fairly knowledgeable about computers and have done stuff like building my own computer, replacing laptop screens, and I've even had my hand at trying to replace a laptop motherboard in the past, but I just watched this video as I was intrigued as to what was wrong and this was a good tutorial for people who might need the info.
Thank you,
I wish I had used tripods and multiple cameras, on my next videos I will do that. Hope this helps someone out there.
Excellent Troubleshooting Skills. Thanks for the video.
Thanks so much! Your video helped me so much. And the Geek squad told me it couldn't be fixed!
Thank you, that worked for me. It was the same problem that you had.
Thank you for posting this very in-depth video. Mine is a different Toshiba model (older Qosmio) but the way it is set up is almost exactly what you were looking at, and same problem here. However, I am not that coordinated or adept with tools anymore, so your video just confirmed I'm going to have to call the technician to work on it. :-( But I wanted to thank you for posting, this was hugely helpful sir!
Thank you and hope you got it fixed.
Video is very good I fixed mine doing the same method. Awesome job on instruction.
Really good video with plenty of fault finding information, thanks for the knowledge.
Thank you for watching, I will try to add more videos like this one.
Thanks for taking the time to make this video. Helped me to trouble shoot my laptop. Still checking. From uk
My laptop was not turning on, I connected the power jack and no lights were on.
As I have seen in this video, I just removed my battery and directly connected to the laptop and it worked!
