Compaq m700 problem (by 2 users)

I had this problem too. The laptop would not start or reboot with the battery in. I could start the laptop and then put the battery in, but would have to take it out when I rebooted or tried to start up later. This was shortly after I'd realized my battery was no longer taking a charge.

I'm not sure what exactly in this fixed it, but this is what I did...

After trying all manner of machinations with no success, I took the battery out and set it aside. It still had a partial charge. These take about a month to discharge on their own. So I let it sit for a month until it should've discharged. It still had a bit of a charge when I plugged it in (I didn't have the patience to wait a month and tried again after about 2 weeks) and the computer did two things it hadn't been doing before - it showed the yellow recharge light before I tried to start up (so I let it charge for a while), then it actually did start up with the battery in it.

Note: my battery actually still holds a charge now, it's not completely dead. I'm not sure if the board recognizes a battery no longer charges and hence won't let you start with it so you don't think you'll be okay in the event of a power failure or unplugging, or if it's just a battery memory issue. Either way, try going without for a couple of weeks and plugging it back in.

check battery terminals in pc .dust and debris can act as conductors thus causing terminals that shouldnt be connected connected and causing a short.you could try as many new batteries as you like but non would work if this is the prob.if you have a small brush that you get for electric shaver;selotape it to a pen(for extention)and use to clean

It has to be something to do with the battery, otherwise it wouldn't boot at
all.
Sounds a lot of money, but a new battery might be the only answer.

Remove "nospam" from return address.

I recently bought a replacement HP/Compaq battery from "Battery Pro" on UK
EBay.  He is regularly listing M700 batteries for as little as ??29.99.  They
will be 3rd party replacements but I was very pleased with mine - arrived in
two days, and charges perfectly with a good capacity and half the price of
an HP replacement.  A new 3rd party battery pack is probably a better bet
than a genuine "new" original with dubious shelf life.
