Recently in the process of upgrading my Dell laptop the plastic cover of the CMOS battery broke off. I held the battery back into the casing with a sticker tape. The system worked fine until I took the laptop to work some weeks after. At work I pressed the power button to turn on the laptop, but it wont turn on. Absolutely no sign of power to the system; no power led, no sound or feeling at all. When I noticed some noise inside the laptop, I opened it and behold the button CMOS battery was no more in place.

I got back home and I fixed the tiny plastic that holds the battery to the casing with a little epoxy adhesive, and used the opportunity to replace a new battery. After coupling the machine back the condition remained the same. Any assistance from this great forum would be appreciated to be able to get my laptop up and running again. Thank you all in advance.

The Laptop is: Dell Inspiron 1501, 2GB RAM, 2ghz speed processor, Win 7 installed. I have no reason to suspect the power pack, everything looks fine.

Thanks Dave for your very apt response. Excepting any slight safety shortcoming, I think I followed the basic installation guidelines, as referenced by you. It is quite spot on. However the problem of not powering on still remains. Still hanging on and believing that the system might wake up one day.

It is yet the to boot. My fear is the electrostatic discharge issues, since every other thing seems okay. If it is, how would I fix it? I have tried to press on the power button for 10 seconds with and without the battery on. I honestly fear the worst - losing my motherboard.

If the Cmos battery was loose inside the laptop it could have shorted something when you switched it on.

I hope I'm wrong but you may need to replace the motherboard.
