Hello.
I received a bios locked 7410 with 25Q256JVEQ ,i dump the bios, unlocked it and flash it back, since then the laptop has no life signs at all except amber led on for as long the power button is pressed, nothing else.
Fact #1 i was unaware that 25Q256JVEQ is 3.3v and i used a 5v CH341A to program it, not sure if the chip got damaged but since then i can read it and write it normally, doesn't seem dead.

Fact #3 i tried hard reset with cmos/main battery disconnected and power... -
I am working on a QN750Q8FNBFXZA. Dead except the standby light. It blinks what appears to be 1 3 1 2. 1 long blink, pause, 3 short, pause, 1 long, pause, 2 short, pause, repeat. A service manual would be very helpful, or if anyone knows these error codes. Thanks! -

Well, a few years after warranry ended, and apparently Lenovo recently ended service and updates for this, my keyboard randomly stopped working, but intermittently,
Refreshing windows 10 didnt help. I managed to safely change over the boot mode from legecy to UEFI, i updated to windows 11, but keyboard issues continued.

hp Pavilion 14 CE-1XXX
MB G7AD-2G DAG7ADMB8D0 REV D
Processor i5 8265U
AFAIK schematics or boardview are not available for this MB, but I used a similar board as a reference (G7AL-2G)
Laptop came in not booting with caps lock blinking 3 fast- 2 slow indicating RAM error. Charging works fine. Found bad soldering on the only ram socket present (2 outer left pins and 2 outer right pins).
Once soldered the laptop started fine and I was able to install Windows 11, upgrade BIOS to version F30 from Windows without a problem, BUT I found a strange and annoying...
