Hi, I've got a P50 that's started having issues when i try and boot it. After I press the on button, the keyboard lights up for a few seconds and i can hear the fans start up, but that's all that happens. I have to press and hold the on button to turn it off and try again, until I finally get the Lenovo logo on screen and then it's fine. If I leave it turned on long enough, I get a series of short beeps, I've tried reseating the RAM modules (2x 8GB under the keyboard), but that's not made any difference. Any ideas??

Right click start, select event viewer, windows log, system, find the time stamp it occured, tell you exactly what happened

about as much use as putting fuel in you car after it’s run out and wondering why you couldn’t get to the petrol station….EFI events don’t register in any windows logs as the NT kernel hasn’t loaded let alone the windows event service running 🤦‍♂️ this is an issue at preboot, you need to look in the EFI/Bios log for POST related events……..

doesnt hurt anything to see if any errors show, if you have the time, explain to him how to create a dump file from the log, and goodluck

how on earth would EFI events be posted to the windows system logs. The issue is happening PRE BOOT

like I stated previously, since you have all the answers and apparently the time, you show him

I would if I had the time, start diagnosis in the pre boot environment as the machine is failing to reach POST anything OS related is immaterial at this point and on the verge of wasting his time.
Incidentally flashing the ME firmware has resolved this issue for me in the past

Damned thing is behaving (for now)... I'll count the beeps when it starts misbehaving again.

update your ME firmware then the BIOS as a start then check the EFI log (if present) for any errors
