Hello, I got my RTX3080 from DELL. The problem was that in the load appeared artifacts and then BSOD or straight reboot PC.
I tested the memory using MATS and no errors were found. So I assumed it was a cracked solder ball under one of the video memories.
I reflowed the memory, and the card started working. It worked for about 2 days, and then after about 2-3hrs of load, the monitor suddenly shut down, and since then it can't post anymore. Temperatures were normal the whole time.
Is this the definite end for this card?
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: Please help me identify SMD components on HP Omen 17
Hello again, I've been busier so I'll comment later.
I think I identified the wrong package and it could be a UML2N in a SOT-353 case.

Do you think that's possible?Re: Please help me identify SMD comp...7294.pdf[/url]

Please help me identify SMD components on HP Omen 17
Hi, I have a motherboard from HP Omen 17 (DAG3BEMBCD0 rev. D) with two SMD components burnt. They are labeled as "L2x" , the package is probably SOT-23-5.
The components are labeled in the picture.
Can someone please help me identify these components? I could not find the schematic for the motherboard. The closest in terms of SMD markings are APL3512 (marking: L2A1, L2A4, .. L2Ax).
Thank you for any help or advice....

MSI GE72VR - blackscreen dGPU not power up
Hi, I have a problem with this laptop. Does not display (even on an external LCD). All voltage rails are present except dGPU power supply (NVDDS) after further investigation I found that DGPU_PWR_EN which leads from PCH is 0V. Can anyone advise me? It's weird that a laptop won't boot at least with iGPU. I tried BIOS reflash and it didn't help.

Ideapad Yoga 3 14" - help with repair.
Hi, i have a Lenovo Ideapad Yoga 3 (14", i5-5500U, board NM-A381). It only light up power led (no screen, fan spin, nothing). I found shorted mosfet on vcore rail. After replaced the mosfet its turning on. Fans spins up and down according to temps but still no screen. I found the coil next to replaced mosfet warm up, then getting hot. I measured the coil and it seems fine.
Can anyone advise where to continue to look for a fault?
PS: Sorry for my bad english.
EDIT: Vcore voltage seems fine.
