Replacing the IC did not solve the problem. I'm unable to figure out the problem as of today. We no longer have the laptop. I'll post an update, and we'll call it part 2 if anything changes.
Same here same laptop model is same problem pls advise should i go to dell repair as no warranty now
I have xps 13 7th gen 9360. Exact same issue. It works when using external display. Just happened last night. It was still working yesterday until i went home from office, display wont turn on anymore.
Same issue here. Still no fix? Thank you for the video. Hoping to find an alternative as I really liked the laptop. Hate to throw it away. What would you charge to fix?
the same problem with my dell latitude 5590.
3 Ic were replaced and it worked and it was charged to me arnd equal to 80$ in my local indian currency
I am seeing this video 3 years after your upload but I have seen the same problem in old Dell laptop from 2007 core2duo. Surprised that Dell is still living with it.
It's interesting to find this video after I sold my 9550 laptop, there was no solution except to replace the motherboard, I tried many popular techs but non of them were able to fix this issue.
The issue is the CPU OR the GPU if its with Nvidia graphics, so simply replace the board or sell the laptop for parts (as I did)
Cheers
About How much did you Garner by selling the laptop for parts
You saved my day, weeek, etc!! Thank you so much for sharing this. It worked like a charm for my xps 9560.
The IC replacement worked for you?
Looks like there are a lot of people interested if this solved the problem. So am I :), looking forward to part 2
Thanks! Nice video. Interesting to see how repair work is done these days.
The way you use the IR camera is the secret of your unique way of troubleshooting
Good to see your third hand for holding the thermal cam!
Great strategy n very practical. So much informations n very helpful for technicians n make a lots of productive jobs. Thx a lot n may god bless you more n more
Is there a part 2 video after you install the chip? I'm curious if you didi successfully fix it? Thanks
Hi, when you locate the hot area, put some alcohol (Isopropyl alcohol 100 % or. Zippo fuel) and power on the laptop, you will see the component with shortcircuit dry quickly. Remove this component and the problem will be solved quickly. No need to remove a component by assumption that is the faulty component.
Except that in this case it didn't work.
Dude he has thermal cam 😂 he don't need alcohol or rosin to locate hot area😂
Good research here. You will see the mosfets on the XPS 15 laptops (9550, 9560, 9570...) run very hot. There is very little cooling there beyond some stagnant air and heat transfer via the board itself. I think there is an ambient temperature sensor at H56 which should throttle the CPU around 76*C; maybe that can be disabled by removing DPTF, and mosfet temperatures could go to 120*C and above, causing premature damage. The thermal paste on the XPS 15 is poorly applied at the factory and typical for most brands; replacing the thermal paste and sealing the fan-radiator can reduce overall temperatures inside the laptop.
A lot of people have tried to reduce the temps of the mosfets (to reduce throttling and lengthen lifespan of components); some blow air into the area others try stacking thermal pads to the metal case. Blowing is tough as there is not much space or wind to spare. Thermal pads are tough as the case is not a very good radiator and gets very hot very fast.
The XPS laptops have their issues but I don't see many of these failures posted at notebookreview forums.
Wish I understood what this meant but does the suggestion in the 2nd paragraph work?
Great video. I come across dozens of very nice Dells with issues like this. Thanks very much for sharing your insight.
Hello! I had the very same issue! Just disconnect the CMOS battery for a moment and put it back on. Just like that I had the issue solved.
hey bro nice video btw i just subscribed where is part 2 i cannot find it on your videos..
I had the same issue, fixed by cleaning dried thermal pasta and re-applied it. Apparently due to the high temperature on the CPU kept triggering the failsafe mechanism to avoid CPU's failure.
Good to learn from this view. Thanks
Did try replacing the cmos battery I replaced that and it fix my issue with dell XP’s not turning on or booting
Hi there, how was your laptop's symptom?, I have a xps 15 9550 i5 and have appearently the same issue as the video, but in mine the fans do not turn on instantaniusly, and after about a minute the laptop turns off by itself. Few seconds before shutting down the fans start spinning and then it shuts down completely. I was thinking to replace the cmos battery cause I think my issue is not exactly as the video, I'm asking you cause I wanted to know if that could solve my issue and where did you get the cmos battery? Thank you!
@
Same issue here.
Mine is 9560. Same issue. Still waiting for part 2 and where to order ic
Is there a part 2 to this video? My laptop has the exact same problem just happened today no more Dell for me after this if I have to buy another laptop it will be Lenovo. Connecting to an external display did not work for me. I have the Dell XPS 15 9550. The diagnostic also didn’t work for me.
Hi! please do u have the 2nd part? please, i have the same issue!
what is the conclusion of this cases..
Great u the best fixer isaw ever
Hi! I leke yours videos, saludos de México 🇲🇽!! 😁
Just read through the 160 comments and only a few suggestions and not one person with a definitive fix, Please drop a reply if you've found a fix
I might have the answer. Over time the thermal paste drys out & needs replacing. On the cpu, this is common
@@CrescendoEvents I've obviously tried replacing the thermal paste, definitely isn't the problem
It's definitely a motherboard issue tho, I just haven't saved up enough to give it to a professional
Good troubleshooting technic thanks for sharing.
Good videos I have learned a lot, I can ask you if you use that camera to repair since I do not see a microscope, I would like to know if you recommend the camera or a microscope.
Thank you
Check out this video, i talked a bit about stereo microscope vs screen ruclips.net/video/uyXbRK4izRA/видео.html
Thank you🙏
This is exactly what is happening to mine, and I have already ordered a $600 CAD refurbished motherboard... :( . I am wondering if you have resolved the issue yet.
How did the laptop hold up the past 4 years after the motherboard replacement?
thanks for the video. Do you know the part number for this power ic?
Good afternoon,
Have you resolved the issue? We've got exactly same problem.
See my comment, got resolved for me.
I can't find part 2, anyone got a link?
wanna buy thermal imaging camera like yours.
but too expensive lol
Same lol.. :/
had a problem with the same dell xps model, but in my case the battery ic got fried. cpu heated up, while the device was not turning on. ic, a conden. and a switch was replaced by myself, and the device was all fine again...
hello, no, i'm german. i replaced these chips: Vishay SIRA06DP-T1-GE3 N-Kanal Mosfet 40 A 30 V Trenchfet 8-Pin Powerpack, TI BQ24777 Power IC QFN-28, and a small cap from a donor board!
np., good luck!
Hey Redi, what kind of capacitor did you take from the donor board? Did you find a tutorial? Some instructions would be handy. Or if you do this for a living, is it possible to send in a black screen xps 15?
Robert Kern the cond was in parallel with two others on the main power rail. took a main vcc cap from another dell mb (nothing special). i‘m living in germany and i run my own little business. idk if you really want to send it in? do you know how to diagnose dead motherboards?
@@retititu I live in Berlin. My 9550 shows the same symptoms as in this vid - blank screen. HDMI out doesnt work either, crtl-d does show, the display is fine. I changed the blown battery a few month ago but desoldering chips might be too difficult for me. I cant tell, if its exact the problem, you solved but I ordered the two chips you mentioned and was about to give it a try before shelling out 430 Euros for a new board from alibaba.
0:48 when i saw this i was like Sr please play with my feelings like this.
Well, the solution to this problem is a bit easier than we might think. You just need to disconnect and discharge the CMOS battery on the other side of the board and that's it (it's a common faulty problem in this computer model and it's caused when it goes into "sleep" mode in windows.
What you do is first connect board to bench power supply then if board itself taking more then 10 milamps then that could mean short somewhere then you check the resistance on all coils and if resistance is to low then you disoldier that coil and on pad resistance will get back to normal on other will be low then you making shor circuit test and detecting hot component using ether flir camera or hands and compresed air......
Hi friend! Please can you recommended which model the Thermal Camera i can buy for my Service Repair. Or which one are you using in this video? I will very appreciate your help . Thanks
XPS 9550 - 512GB - 4k touch screen model here.
Mine was acting up on and off, the same symptom like you all.
At least mine is still able to work 100% on the extended monitor through the HDMI, extended keyboard and mouse.
The touchscreen test and webcam was successful by the Dell test though.
I guess i have to consider myself lucky after reading through all the dell forums/discussions and this video and it's comments.
Still i am going to open up my laptop and see if the flat display cable is loosened up or something.
All in all, this is the worst investment nightmare for me and i regret paying premium price for such a crappy brick.
Did you find a fix and how did it hold up the past couple years
always learning something new from you,thanks and keep bringing more videos
How did you knew the function of that component by just using the numbers? 🤔🤔
where is your store
Have you resolved the issue yet?
Nice job! I also am a subscriber now. I also fix computers, but I do not solder or remove parts, I'm not as talented as you are. What is your thermal camera brand and model number? If you had to buy a new TC what would you buy? Thanks again!
hi bro did u fix it tks
Any update on this? Was the new IC all that was needed to repair the laptop? I have a Dell XPS with the same issue that I'm trying to resolve.
Did you find a solution? Mine is bricked
My 9360 just died too... 3 years of use only....
it was one of the most useless purchase I made still regret it today
Feel your pain man, did you find a fix?
Nice job
Hello, did you get the new DC to DC Converter IC? I'm also in trouble with my xps. Please help me.
DELL xps 9560 - same problem , i had my motherboard replaced by Dell and now 3 weeks later my laptop sometimes start up , show Dell logo and stays... BIOS problem? software of hardware?
----
I updated my bios and firmware with help off Dell support, now it doesn’t happen anymore.
@@zennerstijnglad to hear that, how did it hold up the past couple years?
hello the thermal imaging camera which model is it?
My XPS 15 9550 has a similar problem except that when I press the power button, the light indicator turns off quickly after few seconds. Does of mean that the motherboard is dead?
Awesome dude
its normaly the bios when that happens . take battery out no power hold p button for 40 secs short the bios battery for few secs .and that normaly works
How does one short the bios battery?
disconnect battery then connect the plus and minus together for 30 seconds then replace battery then done p.snot the plus and minus on the battery the plus and minusthe battery connects to@@toperaheem
how did this dell ended...you said you ordered the chip to replace...was you successful?
In my case my 9570 is completely dead - no fans, no display diagnostics, nada. A new motherboard (out of warranty) will cost me approx. 700 EUR or so. One more reason to buy cheap notebooks. My notebook is less than 2 years old (again - out of warranty) and I spent 1400 EUR on it. Absolute garbage.
My 9360 just died 2 days ago after only 3 years
Hi. Are you guys still in business during COVID? I have a 9550, same issue. I would love to get it fixed and use it as a community computer or for my daughter, but a new mobo is 650 plus... Would love to send it to you. I'm also located in SoCal. Great videos.
They are not available anymore
I am having a similar problem with my XPS 9360 actually I am already on a replacement board and the same issue happened again. By chance: did you check the capacitors below and close to the CPU ? In my case on both boards they have short to ground and that makes me wonder whether it was intended by Dell. However, I do not see a direct benefit. Tried using schematic from prev model which is in many aspects close to this board, but it seems like the components are fine, leaving the CPU itself.
Any suggestions?
Thx in advance!
My 9360 just died 2 days ago after only 3 years
Did you eventually find a fix?
@6:30 it looks like the IC is cracked across its corner.
Looks like a scratch to me, it has a little hook on the end and does not go all the way to the edge which a crack would do.
It's just a string of flux. Not a crack.
Your flir batteri thermal batter is low. ?
thank you sir
I had that issue. I got mine at Best buy. I even exchanged it and got a new one but had that issue again. I just requested a refund
Got the same problem with my acer nitro 5 , because it fell hard and lcd chassis is screwed but stayed working in a few days but suddenly went black , it didn't turn off immediately like this one but the keyboard stayed on and the fans spin for a few seconds every time i turn it on :(
Update: 10/20/19
Could it be a clean cmos reset or reprogram the bios chip ic ? I managed to bring it to a third party repair shop and he used a broken but working test screen but it was kinda dim so we had a flashlight shine through at the back , we saw some text at the bios but we really cant tell if its responding or not.
If you can see an image when you shine a flashlight, it's a backlight issue. Screen is not getting the boosted voltage required to turn the light on. You're shop has to figure it out if they do board level repairs.
@@NorthridgeFix thanks
I want to see part 2 of this
Four Kings 👍
I got similar problem led is on and after 10 seconds its goes off. Fans dont spinning at all. And diagnosting show only black screen
Where you located?
Dell are the worst! I will never purchase another xps again.
Hi i have dell g3 3590 when i press power button keyboards lights and charging socket light on for a 1 sec and then going off pls help me for repair
Whare is second videos? How to solve this problem please show to exact what happened? Please sir don't forget
I have a strange situation with mine, it will turn on without the charger plugged in, but if you plug it back in it won’t come on and the light on the on button doesn’t light up, chargers working, so no idea
Did you ever work out a fix, exactly same problem with my XPS 9570
Hi Glen, yes, I was almost ready to bin the bloody thing but had an epiphany, I removed the small battery 3v clock battery, and it worked with and without charger… it turned out to be a loose connection for the battery… it’s been fine since I sorted that out
what happened to part 2?
Sir i am from India.i have a Sony laptop model pcg 41216 w but long time it's in not working due to FFC cable not available.but i get this but no charge light in laptop or not switching on .there r no volt out from battery ,i thnk it's for solid state switch inbuilt with battery but when I connect chaager i get 3.3v from central of battery point not in main 2 terminal of battery there r some volt..237v .what should I chk sir i have no ser manual
connect an external hdmi display but no fix other than ...?
Personally, I had to stop buying Dell products. Used to have great servers back in the day, but after getting burned on my very expensive, loaded Alienware 17 R2 several years ago... no more. The first time it died, they replaced the motherboard. The second time it was (just) off warranty so I opened it and had a look. It had melted several of the wire bundles, board traces, etc. It was beyond economical repair and left a VERY bad taste in my mouth with Dell.
Познавательно!
I got the same problem after I changed the BIOS setting, the secure boot. then the laptop's screen is never on.
In our case it wasn't a bios issue. It's possible that a corrupt firmware can cause this problem.
@@NorthridgeFix if that so, how to fix corrupted firmware on dead laptop?
@@choprapanca208 programming the bios with programmer
I do have the same Problem after changing the Bios setting. Did you fixe it?
Hi Sir , thanks for this pedagogic videos on laptop repair.
I got a dell Xps15Z that gives a fan noise at boot up and won’t display , tried to connect on external lcd /hdmi still not showing anything and fan noise won’t stop even after long pressing of power buttons , please advise. Thanks
Look if the CPU is fried, why would it be able to go into DIAGNOSTICS?
update?
It's a no fix. Most likely a CPU issue.
@@NorthridgeFix i had same issue, it happen when doing a bios update, changing bios didnt help. and still no fix found
I've had this exact thing happen on other Dell machines.
Things to try:
Press the power button until the keyboard lights up. Press and hold the power button until the system powers down. Press the power button again to turn the system back on.
Disconnect the AC adapter. Remove the back plate. Disconnect the main battery from the motherboard. Use something plastic, like a guitar pick, to pry the connector if you have to (don't use anything metal). Press the power button. Press the power button again. Reconnect the main battery. Press the power button to turn the machine on.
If the above does not work, remove the CMOS button battery for 30 seconds. It should be to the right of the right fan, possibly under a bit of thermal tape.
If none of that works, or if the issue repeats, you have a bad motherboard.
Hi sir how are you... Sir please lenovo X250 bios password remove how to....?
👍👍👍
dope
same issue why dell whyyyyyy
sir where is part2 ??
Same problem here
part 2 ?
Need more volume , please.
Judging by the first two minutes of the video I'd say that it is a bios ic issue...
anyone figure out the fix. this is exactly my problem
It happens with me and couldn't figure out the issue as being having background of this area, so started searching every possible video i could find then one person's video assured of this case and i tired and out of 5-6 tries, 1 time it worked and it's still working till date for around 4 months as of now.
@@anjulkumar2298which video was it and what did the person do to fix this?
I type it in Google got Honda 50
Please anyone still experiencing this issue like I am and has found a solution to it should reply to this comment
Well if you promise to do 2nd part, do so
Otherwise dislike
Yes. Update please. Chips from china only a month away. What happened?
I have got it fixed. Dell used to replace the whole unit or motherboard to fix the issue. soon will upload a video on how to fix it.
how did you fix it?
If you are unable to do a video can you describe your fix in text?
Please do share the link to your video or some info of solution here in text.
I solved it, the power connector has a problem, it is the same dell m3800
which power connector? Clearly the laptop has power?
Maybe the solution it's easier.
I would try to remove the peripheral parts one by one
Same exact issue, Tried that with no success :( W/e the issue i'm fairly certain it is thermal related as this laptop has well known heat problems in this exact area and in newer versions they heatsink those mosfets
I DONT EVEN SEE A LIGHT
I have exactly the same laptop and problem, fu#k Dell
