Re: my compaq cq 42 no power

The only thing I can think to try is to use only one memory chip and see if it starts.  Try both slots and then try the other memory chip.

Re: my compaq cq 42 no power

I am wondering if that bios may be bad off the HP website?

Re: my compaq cq 42 no power

My best guess at this time is that someone will have to reprogram you bios.

I think you could leave a message to this place.  He did fix my bios for me.  There are other people on eBay that offer this type of service as well.
