I have exact same laptop at home, with exact problem - no power etc. when i finish i will say something more. Thank You so much !
Your videos are so chilling :D hope to see some live stream ! :)
Remove battery and press power button it will open I had the same laptop same problem but worked
Hi Sorin,
Because I'm doing just the same things as you just like me at the hobby level, I watched (in 2 days) almost all your videos including those with the family I feel like I have a new close friend. Thank you for everything. All right, dear friend Gabriel
Thank you :)
Thanks mr.soren , it is useful lesson for us, Thanks
Fantastic job on all the videos, learned a lot and keep on learning from you! Hope you can get a proper internet to livestream someday.
Thank you :)
UPDATE! Problem solved! I finally found the BIOS chip and reflash that with SOFI Flypro device by downloading the BIOS binary from a russian site. I found the BIOS chip by meter the voltages on each chips. My laptop: Lenovo G50-45. So if every voltages are OK, you have to find the BIOS EEPROM and reflash it with an external device. Thanks, master for your vids!
No idea what you are saying. Explain in plain speak. What do I have to do?
Thanks for the epic videos, Sorin! Today i just got the same issue with this laptop and your video was huge help!
Glad to see you, but I wish it would be proper vacation video, not working video. They should pay you more for coming in at such time!
i wish :)
Professor, Merry Christmas and a happy new year to you and your family.
Good life

Hi there, thank you so much for your videos, you've saved me on multiple occasions! I need your advice for a the same Lenovo G50-30 as in the video but with a i3 chip. The problem is, I have both LEDs working, but it doesn't start up and shows nothing on external screen. Also please explain how exactly do you short the CMOS battery since it's not visible on the video. Thank you in advance!
thenks
Thank you. I shorten the Biosbattery from my Asus Notebook (no screen) and now it works fine.
i have same laptop, try to repair it and do same thing that i saw on blog. thanks a lot. more power.
Hello Chief, you are doing good work
Thanks man for all videos! Tips: You can also reset the Bios by pressing power button (about 15 second) without open the laptop. :-)
Hmmm.... how this is posible?!
with no power connected I assume? I´ve to repair one of these laptops for a friend with the same issue.
hurray!again beautiful video.
thanks
i've learned a lot from your videos and now watching almost all your video. its educational and entertaining watching and listening to you. hope we will get to see more of your videos soon. :)
owh ya, thanks to you, i've manage to solve my mom's laptop problem. :)))
Thats really great!
Man you a genious! What temperature you used on the ITE chip?
No, just lucky this time. 500 C
@@electronicsrepairschool I reviewed this vid again, Luck counts too 'cause you get pay and the customer gets his data back. Amazing I didn't remember you actually heated a iTE chip. First time I seen that. The "Sorin Method" !
I'm confused as to what you did with the power management chip. Did you just hit it with a heat gun and press down with something? I tried looking for more info on your technique, but did not find any. Thanks for your response!
i know, blind luck, but .... i think from the graphics chips point of view, heat can change a lot of things inside of a chip
Everywhere in earth a man has to quietly listen to his wife only.....
hola buen dia tengo la misma maquina y por suerte gracias a tu video pude recuperarla el tema es el siguien el chips levanta mucha temperatura y despues de unos minutos se apaga es desir que tendria que revisar y tambien me paso que enfrio conecto el cargador y no enciende ningun led tengo que desarmar y volver a realizar la misma operacion con calor
gracias por tu ayuda
How did you reset the bios battery? I have watched the video 3 times and I cannot see that moment. Could you please help me? Thanks a lot
9:57
Thats weird watched that (and other your videos too) checked all power 19v present, battery power too, shorted bios battery for long time, battery voltage seems to be fine 3v, 5.5v present, all fine, heated startup chip with hair dryier for now very close to the chip. Chip was red hot, but nothing wont turn on? Do you have any thoughts? My model is same but with i5 in it. Dont want to throw it away its only 1 year old. Was working fine before. Changed charging port as positive wire came out and dont really know how did u fixed that. Can not find anything what was its problem. What county are u based btw? I might just come and drop you laptop if its close enough. Hope u can help. If no just let me know u cant help me. Anyways very good videos! Loads to learn from you already!
did you get any solution facing same problem here.
@@soccerushtv8511 yes, over heating in gpu chip, and cpu burnt too.. sadly my misses said that she used laptop on the bed, and covered all fan holes to let hot air out. I had to bin that laptop.
thanks very good
Hi, you can repair hard disks? You can make video as you attempt to do so? Just a suggestion. Thanks for great videos. Good job.
woow thanks worked fro my LENOVO B51-30
Thanks,it's helpful. You have any video on Lenovo b.51-30 no power
my laptop is also lenovo g50-30. it was working.and I plugged it into the charger while the charge was running low. shows that it is charging but the percentage did not increase and turned off. I replaced the battery, the laptop burned out and worked, and turned off again without power. then the indicator also did not light up. this laptop does not burn only through the charger without a battery. in fact, can this laptop burn without a battery (with charger)?. if you know the condition of my laptop please help me. thank you so much for your help. I look forward to your reply.
Thank you
good
I really do agrre with your opinion about this (hard to say) laptop.
hi, thanks for your video, i am from argentina, i have the same model, but when i conect to 220v, the light of charger its on, and the power light too (its start alone se prende sola ja), but nothing in screen, even with the vga output or hdmi, you think its problem of the it8586e? thanks. sorry my bad english
No, it's most likely the graphics chip.. You will need to reflow it using the heat gun.. It should work. Note that it's not permanent solution and you will most likely have to do that again in few weeks/months/a year.. He has a video on that exact fault and fix. You should watch it.
Also before all that, try shorting the CMOS battery
Beautiful video! For the power light to come on for me on the motherboard, I used the positive lead from my Volt meter (with my negative lead on ground) and probed the outer connections of the ITE chip. I learned that the methodology I mentioned above & ITE chip connection is the problem when the issue reoccurred and I had to fix it again ("waste of time") lol. At any rate, I took a photo of what I did to resolve my issue. If you want a copy of the photo, please send me your email.
can i have a picture? tosnew (a.t.) ultraportal (d.o.t) eu - did all steps from video and still same... not fixed. If i hold power button for 20 sec, powerlight will come on, and charging but can not turn it on.
Isaaliu@yahoo.com. please send me an email
sir i have same laptop problem is when press power Button the led on but no display and no Amps draw on Bench Power Supply .What is the cause of this problem
Good Job , Gracias 🙏🏾
Hello i would like to say that all of your videos are great and enjoy watching them. I have a problem i wish you could maybe give some tip in repairing my system. It is the same shitty laptop as in this video. I have tried with two repair shops already and both are saying that the cpu is dead which i dont believe is true. I want to give it a go myself i know basic visible fault repairs. The equipment i have is a digital multimeter and a soldering iron. The things im missing is power station and hot air station. I have tested for voltage with multimeter on the board and it stops at one of the switching chip near the power connecter and does go any further rest of the board. I want to ask you that is there anyway we can test the cpu is dead or not for sure.
got it thank you!!
nice video!
Can we add heatsink for Lenovo G50 30? With fan
You can do, but easier will be to use an Cooling Pad for laptops.
I have same laptop but after water domage no want to display any think can u give some advice please
I found that when the adapter is connected, the PU401 chip will overheat right next to the memory.
nice class
How you reset the bios
excellent
Hi please I want to ask. I have a Lenovo B50-80 and I can't turn it on. Once connected, the board heats up in the processor area. When I measure the USB power I measure 0.2-1V. The main battery has 2V. Small battery 3.1V. The power transformer is fine. After pressing the power button, the netobook does not start, the diodes do not light up. Thank for help.
Hi i cant see exactly how he reset bios. He sort the top of the battery with the negative pin?
After plugging my Lenovo g50-30 into charge. It went off. It powers on for 10 seconds, shuts itself off. Power, and charging lights are on, then go off. I've looked at the mother board, it has a soldered in chip for bios. Charger fine. Anyone got any advice
I have same probleme power light abd cam light ...running for 10 second after....nothing....any idea about the solution plz
Just got a laptop with the same problem!
Hello I am working on the same laptop I followed this video but nothing works when the laptop has battery in and is plugged on charge the battery icon flashes orange but when I disconnect the battery I have no lights and when I disconnect the charger I also have no lights
Hello Sir. I have a lenovo b50-80 which runs normally and shuts down completely after 2-3mins. What could be the problem? No overheating at all
for me the led 1 on the motherboard is on but the computer is not turning on , so i guess that issue is the the mb but im not sure .
Hello! I have the same laptop but the symptoms are the following: if I press the power button the laptop it's starting the power but after 3 seconds the power it's shutting down..If I press again the power button the laptop it's just booting fine..what can be the issue? RAM it's ok. hdd it's ok, bios it's ok..Also, when I try to power the laptop without the charger connected(battery power only) it refuses to turn on...after 3 seconds the power it's shutting down and if i press again the button it's not booting..
Thanks a lot I dit it differently but worked thanks sirr soo muchh
Hello what used laptop would you recommend for about 200$ , was thinking of thinkpad t420 i5 2520m , is it any good ?
Thank you
Hey man. I discovered your channel yesterday when I had this laptop to repair. Can I ask please exactly how you shorted out the bios battery? I could not see your method very well from the video? Thank you in advance.
hi, just short the pins with anything metal
Electronics repair school so touch negative and positive terminals of the connection?
yes
Thank you. I did all the steps in your video but still had no luck in restoring power. Oh well.
most of the time its a fault there, its not all about restoring the bios, sorry
That's ridiculous, i never saw a laptop processor without a fan before..
hello i just fixed a i7 g50 with your help in this video, i jumped battery no luck,,,, I heated up the chip and the laptop powered on and Continue to work for several hours.. but after a few power cycles it would do the same. after it stopped working i jumped the battery but no luck,, 5 minutes later I tried again Powered up fine.
After playing with it I realize now that resetting the battery will get it to boot.. If I close the lid and I let it go into power save mode it will never wake up.. Requires me to shut down with the power button After that it will not turn on and I would have to start the process over to turned on again. there is a few seconds after resetting battery before will power on..
I was wondering if the laptop in Video continues to work fine after it was Returned to customer. and if replacing this chip could be a permanent fix,
How many volts does the pin in the middle of rectangle lenovo adapter? Pls
Sir jis ic ko aap heather kiye he use macanic ne damage by sharing bataya he qa sambhav hai
Hello Sorin! I'm new. In wich mode is the multimeter set? Always is showing mV movement although the probes aren`t touching anything.
He is touching probes with his hands, charge on human body causing that issue.
When will you buy an anti static mat???
My power light is flashing and it at first came on but I got up left it and now it will not come back on and power button is flashing also.. HELP Lenovo. Same model as this one.
salut!, am un lenovo g50 si daca folosesc o baterie de la alt g50 laptop ul functioneaza insa nu incarca bateria si nici nu merge fara baterie deci nu primeste curent, am masurat in interior la cablul de la mufa unde intra in placa de baza si voltajul este ok, sa fie un mosfet??
Too bad I'm not facing the same issue here, your work is awesome and really instructive. On my board the ITE chip looks good but I was able to trace an other small component which heats up fast when the charger is connected. No lights for the power or the battery. The component is named ND4MM, I can't find what it is. Any idea ? Thank you again for your work and time :p
I have sameone..can i able to install a cooler fan in it??plz help
Please help! I have the same laptop. I have LED power light but no picture anyway. Backlight won't come, the screeen is black. Checked the VGA output with monitor, nothing. I have good voltages, I have 19V, 3.3V and 5V on the power supplies. When insert battery and plug the charger, charging LED is OK! Only black screen at all. Does this mobo have BIOS chip on board or inside the startup chip? I cannot find the BIOS chip. I shorted backup battery too. What could be the problem if ANY voltages are OKey? CPU fan spinning, CPU and GPU warming like normal. THANKS!
same problem me

Hi my pc Lenovo b50-70 is not work ..restart in 5 second...why!
Again a lightening speed repair! Too fast for me to follow. What was the trick this time? Was it the 500 C on the ITE chip or the tweezers on the bios battery that did the job or both? This shop cannot survive without you, I guess.
:))) probably the tweezers on the battery :)

I have exactly same issue, but shortening battery on bios did not work, i dont have heat gun but used hair drayer with extention pointing to whole chip, and pressed down still same. May i have photo what have you done? tosnew@ultraportal.eu thanks.

how to reset bios battery?
Sir my lenovo g50-30 laptop no pawer on please solustion
so this one here like my dell we spoke on email - when it start light coming on but 2 beeps and goes off and i am thinking it is bios chip or starter chip?
probably not, those beeps mean your motherboard perform the autotest and a error its found.
sometimes it beeps if i take out bios battery and when i first put back battery and plug in power it beeps after light comes on and the light goes out and nothing
what model no?
dell inspiron 15 - 3878
oh, yes , now i remember, i wish to have a better idea about what can be checked there
I have this problem and I think what you did is the problem but I don't understand what you told me to do at the end can someone dumb it down for me 😂

problem is, this problem will come back again and again.
Hy,what can i check if my laptop turn on but after 2 seconds turn off?
I have a similar model, the g50 45, It has the same problem, i thought it was the charging port at first but it turns out that it wasn't. There is this one small component that heats up extremely. I'm sorry but I don't know the names. Maybe a transitor? Is there anyway I can send you a picture? I really need to fix this. Thank you in advance
yes, send the picture
I have a similar problem , and i also have a lenovo g50 as well but my issue is that it turns on for a few seconds then it just turns off again.
hello there, same problem here please tell me is that big chip"it8586e" he heat up, what did u do!
im waiting here ok bro
Ty Evans I had that issue before, now it won't turn on at all. I think you need to replace the charging port. The DC-IN Cable. Very cheap only about $13 CAD
replace the chip, kakay limono
But on this case this is a propper shit laptop.
I listened to that 3 more times, love that "prpper shit laptop" and that nice russian accent :D
sorry, usually i'm not using bad words, but the view of the laptop made me angry :))
abe ye kaisi repairing hai IO heat kiya or laptop bana diya... this is not a permanent solution..
