#Thinkpad X1 Carbon 2018
I hardly used it for a while, tuned it on again and if I power it on now, it lights up for about 2 seconds and then turn dark again.
I tried:
Recharging for hours
Unplug battery
Unplug CMOS battery
Press battery reset
Any more ideas?

@[email protected] If the CMOS battery is truly dead, then the embedded controller (which in more recent PCs has replaced the RTC chip of ye olden days) has probably lost power as well and may be stuck in some odd state, so I'd definitely try a new battery (just a hunch, though). The other most common failure mode of old(er) electronics are leaking electrolytic capacitors, any signs of that?

@[email protected] Thanks for explaining! 🙂 No, I did not see any problems on the board but I can only parts of it.
