This problem just began occurring. I have a Compaq Evo N600c Laptop from mid-2001. Here's what's going on. about twenty minutes ago, my laptop was suffering serious performance issues due to overheating, (I know this because normally its a very "Zippy" Laptop). So i powered it down, removed the HDD so it could cool off, and removed power from the computer. about two minutes later, i noticed that the battery was also hot around the terminals, so i removed it as well. now, about a month ago, my CMOS battery died on me (since this laptop is at least 8 years old). So i plugged the power back in, and the laptop suddenly turned itself on!
it has done this maybe twice before, and it was fine once i turned it off again. So i turned it off again. Then it turned itself right back on!
So i turned it off agin. it turned on again.
this went on for several minutes.
finally, i pulled the plug to keep the processor from killing itself. i inserted the HDD and battery again. then i waited for the cycle to continue. it didn't turn back on. i plugged the cord in. it didn't turn back on. finally, i removed the battery, unplugged the cord, and plugged it back in. the laptop began powering itself up automatically again. so it appears that this problem only occurs when the battery is disconnected, and ac is plugged in. i understand this is not that big a problem, but i am afraid that the processor may burn itself up. Can someone tell me what the heck is it doing?!?!?!?!? I REALLY don't want to have to buy myself a replacement laptop! Please help!!!!
