Notebook not powering on (by 9 users)

Will not turn off or on, screen glows.

I have a T21 that has the same problem and I have a theory as to why.. granted its only a theory because I have yet found anyone who will verify or even look at it without charging 75+ per hr or have it shipped away for 2 weeks just to verify this.

Going all the way back to old school computing I suspect that the CMOS battery has died. The reason I think so is that this problem happened several months ago and I put the laptop away until I had time to look at it. While working on another system I got bored while waiting and decided to try and see if the T21 would fire... lo and behold it started to go through its power-up and boot process... but then stopped responding. After about a dozen or so power-off and power-on attempts to see how far it gets through the process it went back to only brief flash of the power light when I press the on button and then nothing... btw the charge battery light does show solid green meaning the power supply is stable and the battery accepts a charge.

Now here is the kicker... all batteries are chemical reactors in the sense that this is how they produce electricity. Even a dead battery still has a low amount of chemical reaction internally. Now if you had a flashlight that died and you set it aside for a few days/weeks/etc and then just for laughs turned it on it would in fact light-up.. maybe even moderate brightness or just dim for a few seconds/minutes then eventually it would fade and go dead again.

This would also occur with a car with a dead battery because although you are not using or charging it.. the chemicals inside are still reacting... slowly but after awhile enough to produce enough of a charge for a brief time to indicate some life.

IBM/Lenovo won't talk to you unless under warranty or pre-purchase an agreement in which then they would be more oriented in selling additional products/services than solving such a simple (read as unprofitable) problem. Additionally most local repair listings (77056 area) are for companies who promote being more oriented to being a big business than a personable solution to the individual (again trying to charge 75 per hr just to orient you towards spending more than its worth)

Now why don't I myself just get one and replace it... well long story short there is a valid reason why I moved from hardware to software years ago.. I'm one of those guys who can walk past a car and hear exactly what is wrong with it (same with a pc) but you really do not want me to open up the hood!

got the same issue. I have replaced memory and hard disk and cmos. and still got the same problem. have try to start from ac power and from batt power and both. this is weird the first try regarless of day hour will start normally. and can be restarted from windows option many times you want and will start fawless. BUT once you turn it off wont start againg unless you pull out battery and try from ac power along , or pull the ac and try from batt many times . you never know but after switching from power source BINGO!! start up after many attempts.
can this be motherboard? if so why starts fine the next day?
pls help.!! thanks
