Re: Lenovo L340-15IRH won't start

if it is as you say it is, then what could likely be the cause of this? if it wasn't the BIOS, would there be any other that would cause this issue? i've taken the offending upgrade parts and reinstalled the known good ones so i know they are stable....

Re: Lenovo L340-15IRH won't start

i cannot make that assumption as i do not know what could cause the system not to POST. if it wasn't POSTing, shouldn't it have been triggered by a fault in the BIOS?...

Re: Lenovo L340-15IRH won't start

so, i erased the chip and reflashed this, and i still have the same issue.

it still does not continue posting, power led still blinks continuously, kbd lights up then turns off, fan turns on, off then back on again.

what could be causing this?...

Re: Lenovo L340-15IRH won't start

thanks! will try this, and will let you guys know what happened next.
keeping my fingers crossed!...

Re: Lenovo L340-15IRH won't start

help, please!

L340 15IRH NM-C361 rev 1.0 model.

no post, no display. power led turns on, kbd backlight turns on, then off again. fans turn on, off, then stays on. RAM and processor warms up, but nothing on display. not sure what happened to this, but definitely stopped working after upgrading the m.2 SSD and RAM. removed the new SSD, and replaced the RAM with the original does not resolve the issue.

was able to retrieve the firmware from BIOS for you to check. please check if it needs cleaning or fixing....
