Morning post from Sorin, handy work distraction

Thank you for following up from the preview "lets have coffee together". Good one.

The week has 7 days (even if the first one starts wrong). Thanks for sharing. All the best.

Hi professor, I really tank's for your videos, you are a best

I swear the trick to laptop repair is to start every job saying "ur a nice laptop"

i cant believe, is it a dancing school or a electronic repair one! time to gamble ^^ huh? love ya :)

*Let's go Sorin! :)*

I want that terman camera !!!

hello mi frend lov ur work, supatanx

Can you make a full course video on how to troubleshoot laptop board until the last piece

Are there resistors and caps to test on the chip set? Maybe test them? Who knows, maybe that will fix it.

I appreciate your knowledge Sorin. But i must disappoint you. I saw exactly the same behavior on my thermal cam on the chipset, the laptop had a picture and was working. It was a Clevo 7th gen Intel board which could not charge the battery correctly and could not work on ac charger alone. The fault was a partially burnt 0603 2.2 ohm resistor in the charging ic section, and i replaced the charger ic in any case, too. This did not solve my problem. At the end my thermal cam revealed the fault, and it was a cold solder joint on ac charger jack on the motherboard. After resoldering all pins, the problem was solved. Laptop charges battery correct, works without battery, does not turn off under load. I went away from the topic. This theory with the pulsing chipset die is not very reliable. This chipset on that board that i mentioned behaved pretty the same like on your board. So, it could be a waste of money and time to replace the chip. People regular jump first to external bios flash. Which is not that wrong. But in many cases not the problem. In your case, hard to say where the problem lies. You can suspect the graphics chip, too. I read randomly a few comments, and someone mentioned that you said the owner tried already externally if a picture is present. So my guess, the graphics chip. But to be real the diagnose process is very hard, and all is a guessing.

what s the resistance value on the chipset coil with the ground ?? CAN U SHARE VALUE?🙏

very cool

I recently had a similar fault after changing RAM timings on bios on my acer laptop, doing this cmos short didn't reset any bios settings in my case, even after leaving the board without any batteries for like 2 days. After that i was able to reflash the factory bios with correct .FD file name and usb stick (fn+esc+power button) and it came back to life, so i don't think the bios battery stores anything other than time probably because of security reasons, not sure though.

You didn't mention what laptop model you are talking about

If the laptop has an external hdmi/displayport, connect it to an external monitor, and/or disconnect the internal monitor cable. If it has an IGPU and a dedicated GPU, like a lot of laptops do, it will actually often boot from an external display if there is a problem with the igpu or the internal display.

Hi, beginner's question, what's the configuration of the hot hair when working with laptops?

@carlosgarciaoropeza5480

@fritzsander: It depends on the type of electronic component; but it's good practice to start with 350C and 30 airflow. Experiment with damaged or unrepairable PCBs (printed circuit boards). It records the size of the component, the temperature used and the time taken to remove it. Then move on to the complex jobs, ie removing components near where there is any plastic material (try not to melt it by protecting it in advance). Another way of saying it, practice makes perfect.

So was it fixed?

I had a Nitro 5 come in a couple days ago; the Chipset kept overheating. The customer complained that all was fine until instantly one day it just started chugging like the GPU went or the SSD went bad. However, all of it was an overheating SB Chip. I would bet, if it kept being used, we would have arrived at this same issue, a dead SB Chipset.

I have a Acer Nitro with basically the same issue here, first a BUC converter had a short near the ssd at the bottom, replaced it, now get the same issue as you show, correct voltages on board and ram, and that same chip getting hot under thermal cam.

He has done that before, but the problem is finding a GOOD one. It's a lot of work installing one just to find out it's a dud.

I have the same laptop, doing the exact same thing. Finding out that the mfg won't sell or repair the chipset is more than enough for me to never buy another Acer product again. Certainly won't recommend them either.

Sorin, I love watching you, but please stop spoiling the issue in the title or thumbnail:(

I thought the first thing to check would be ram. (?)

No backlight or no image

👍👍👌👌

No, no ham, duck :D

But will it blend?Thats is the real question..

Try to switch memory to another slot, maybe video working for couple minutes before becoming hot..

I had the exact same problem 2 days ago. I changed the chipset, but the problem persisted. Could there be another cause? I mean, how likely is it that 2 chipsets would have the exact same issue? However, my laptop is still running. But also the christmas lights with the new chipset....but laptop is working fine even benchmark. But i dont know how long it will run 😅

In the Philippines if they don't know what to do or something is intermittent, they will just use the hot gun and focus that on the suspected component or everywhere where it could go wrong due to heat damage.

This mainly happen when gaming on a soft surface or cloth where the laptop can't breathe properly which builds up the heat loosening the solder or damaging components.
