Laptop can't start anymore
I have an old IBM laptop 755. It used to work fine. Recently, after I plugged in the power, it refused to start. I don't think it is even get to the boot stage. I can see the power, battery, charging and suspend lights flickering and the disk drive making quick and repetitive noise. After a few hours, it started the normal booting. The machine runs ok if I don't turn the power off. If I do, it takes longer and longer time before it can goes into normal boot (last time, it took about 10 hours). It happened a few days ago that I have to unplug the power for a brief second and it is now in that "kicking state" and can't start again (more than 24 hours now). I don't think this gradual failing is due to a broken part. I have a feeling it is something like the CMOS battery is bad because once it boots, it runs just fine for an extended period time, but from all the readings I got, the machine should at least display something or beep for a bad CMOS battery. Underneath the keyboard, I found two batteries. One is a Panasonic 2020 (one thin button) and a group of three button batteries. Their voltages are 3.91 and 3.6 respevtively. I don't know what should be the working voltage (or is this a battery problem at all). I appreciate any hints and suggestions. Thanks.
