the computer battery

If the battery was dead would that cause the computer not to boot? or write text on the screen?

Well if you have a laptop, and its only power source has been depleted, it just might have negative effects...:rolleyes:

What about a desktop computer?

I'm not really sure, but I know that it takes a really long time to burn out a desktop's battery. Some of the new ones I hear last like 10 years.

Yeah, but would a burned out battery cause the system to be unable to boot?

I would imagine so, that if your motherboard battery was dead, your BIOS would be unable to initialize and hence fail to boot properly, if at all.

However, I would suggest finding other problems first. Those batteries rarely fail, and i would imagine your motherboard would have a beep code built in to let you know if it was dying or gone..

If the battery goes dead it should only lose the CMOS settings,
etc.. I had a system that had a battery that went out and it
booted it just had defaults set for everything (lost the date/time,
etc.).

If you have an old computer, then you won't have a problem without a battery, except for clock failure and inability to retain a BIOS password.

If you have a newer system, then you might have problems, although if you have a new system with a dead battery, you have very bad luck.

Basically if your system if old enough for the battery to fail, it is probably old enough to operate without the battery.

I haven't heard of too many people's batteries going south. Does it sound like it's running or does nothing happen? You might have a bad power supply or maybe fried the motherboard.

Hi,

If you take the cmos battery out of new machines, it doesent start up at all,

Well this has happened on all the machines that I have tested.










And To All Those Opposed, mmm Well!!!
