Thinkpad
For IBM/Lenovo ThinkPad laptop enthusiasts.
@fairsuchen Sorry to hear. Pressing the power button for a couple of seconds while having the battery disconnected helped me to get other ThinkPads back to life - but I’m not sure whether this works for the X1C series.
@[email protected] Did you also put in a new CMOS battery? And disconnect all power sources and let it sit for a few hours before re-powering it, that sometimes also fixes residual nonsense values stuck in some registers.
@[email protected] Yes I did unplug all power sources. I did not consider a new CMOS battery because I would need to buy it and I thought a dead battery would just make the BIOS setting reset i.e. it does not explain that the computer won't start. Am I wrong?
@[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.
@[email protected] with a bit of bad luck: https://www.quora.com/What-are-the-signs-of-a-damaged-motherboard-in-laptops-Is-it-possible-to-repair-them ... There was a series of Lenovo that had these issues, not sure which year though
@[email protected] Too bad - thanks for the link!
@[email protected] their support may be able to at least give you a diagnosis, maybe you're lucky after all and it's something else
