Pix for posting
-
I have a customer that brought in a Lenovo Legion S7 15ACH6. The problem is that the laptop is not posting.
My first thought was to take out the DRAM and put it back in.
No POST.
Then I swapped the dedicated RAM with good known working RAM.
No change.
I then measured to see if 1.2V was being generated for the memory to turn on, so I measured PL600 which is where the output of the 1.2V rail is.
Resistance was good; measuring ~40Ohms with the slotted RAM in.
I took the slotted memory out and measured again.

Hello everyone,
I have an ASUS Vivobook 14 OLED M3401QA which is not posting. Currently when plugged into power/turned on the power indicator will illuminate and the battery indicator will flash white roughly once every 3 seconds. Leading up to this it would sometimes turn on and then other times not turn on, furthermore it also showed a screen saying "new cpu installed, fTPM/PSP NV corrupted or fTPM/PSP NV structure changed" and then a screen telling me to recover the bios however it is no longer even posting at this stage.
The diagnostics steps I have attempted... -

The system does not even POST, display is black,
LEDs on - power led, aiplane mode, capslock fpr few seconds in the start(when connected to ac power) only.
When did the problem happen?

Hello all
I have a Lenovo ThinkPad P14s Gen 1 (S/N: PF-2LJ7LF) (Type Number: 20Y1-0011US) (Board Model Number: GT4A1 NM-C801) that appears to not be POSTing after the previous owner attempted to troubleshoot some display issues, and in doing so while trying to install updates (BIOS suspected) seems to have bricked the device. The device charges (LED indicator light turns on) and powers on (power button and keyboard light up), but fans do not spin and the display remains black (no backlight either). Pressing the caps lock key also does not light up the LED indicator.
