Appears the motherboard on my HP Compaq NX6110 has fried. Have been having intermittent problems with components (USB ports, PCI board, power jack, etc.) and unexplained hangs. Hung today, and now machine doesn't get through POST. Pulled the RAM and tried to power up. No beeps or alarms, which tells me that it's not completing the POST. Wondering:

1) could it be a bad CMOS chip?
2) should just replace the motherboard (it'll have to be a refurb) or just get a new notebook?

Thanks for your input!

A faulty power adapter can cause problems with laptops.

I can not tell you if your motherboard is fried or not without doing actual tests on it.

Laptops suffer from CPU heat sinks that get clogged with dust and various internal connection issues on pressure lock connecters also called Zero Insertion Force (ZIF) type connecters.

The major issue is corrosin on these contacts, nothing special has to happen for this to happen, it just happens.

If you intend to save this laptop on your own, I can offer you a link to a web site that may help you diagnose your problem.

Here is support from HP for your laptop http://h20000.www2.hp.com/bizsupport/TechS...p;submit=Go%20

Manual and a lot of other information on your laptop. http://h20000.www2.hp.com/bizsupport/TechS...SeriesId=449877

You can use all the links provided on the pages I have provided to hopefully find a solution to repair this laptop.

If anything it will be a learning experience on how to repair a laptop.

Thank you for your advice. I have kept this machine alive for 6 years and it seems to have reached its service lifespan. Cleaned out the heat sink and guts a few months ago. There have been several intermittent problems that I've traced to the motherboard (the USB ports in particular) that appear to be just the basic corrosion you referred to. I'm just going to get a new laptop and keep this one around in case I happen upon a refurb motherboard for a few bucks. Then it will go in "backup" mode.

Thanks again for your advice.

Richard
