My Thinkpad T22 is having problems booting. The battery light and the left green light turn on okay, but more often than not (and the problem is getting worse) the machine won't start.
I've read many, many threads on this all over the web, as it's apparently not an uncommon problem, and have tried just about everything suggested: holding the power switch down, taking all the peripherals out, letting it sit in the refrigerator with the battery removed, et cetera. About the only thing that "works" is to let it sit for a few days, ie try every day and hope it will boot.
My question: has any definitive cause of the problem been found? I have read speculation that a capacitor on the motherboard might be bad. Is that it? Or is it something else? There's nothing wrong with the (Li-Ion) battery and the power supply. I am planning to replace the CMOS battery.
The data and the peripherals are all okay, so I guess I could get a new machine; but this thing has been useful and I'd like to keep it around if possible, even when I do get something newer.
Thanks for any help.
