Having problems with your IBM ThinkPad T40 2373 Notebook ?

Laptop does not boot except when on AC, not a battery problem.

\015 Hi,I have a Thinkpad T40 and it works well when connected to the AC. However periodically when connected solely to the battery it will not switch on regardless of the charge in the battery.If booted using the AC with the battery plugged in the laptop will continue to run on the battery, just not boot up. (It starts and then stops before loading the initial IBM screen.I think it might be a CMOS problem, as if left plugged into the mains for a long period of time the problem seems to disappear.I replaced the battery to see if that made a difference, which it didn't and now I'm out of ideas.Thanks.Tom\015

Answers :

It won't have anything to do with the RAM. You probably have a dead or dying battery inside the computer. It is a large button cell type battery, mounted directly to the motherboard. It should be replaced by a repair shop, since any amount of overheating of the motherboard can be a disaster.
