I have an HP laptop (dv3-1075us, out of warranty) that won't boot, and I'm looking for ideas/education before calling/paying for HP support somehow.

I've gone to the HP users forum and got limited pointers.

When turning on, two LED lights on the KEYBOARD flash: Num Lock and CAPS Lock. They seem to flash twice almost together, then the main screen flashes (it's trying to boot, but then fails), then these keep repeating over and over.

I was pointed to an HP LIST of what the flashing LED lights mean, but I'm not sure how to use that given what I see. It SAYS 2 flashes of cap/num lock means something's wrong with the BIOS. But it implies I should see these two flashes, then everything stops. Or I misunderstand, so I'm not sure it's the BIOS.

Any help in interpreting what I see?

If it is the BIOS, any suggestions on next steps? Places (in the SF Bay Area) to take this?

Suggestions on where to take this for a straightforward (and inexpensive) diagnostic/troubleshoot to at least confirm what the problem is?

Stuff was backed up and I have a different computer to use temporarily, so I can approach this in a non-emergency mode.

Thanks for any ideas/help/etc.

finAre there any messages/errors shown on the screen? Try removing the HD and make sure its firmly seated on contacts/connector. Look for the manual describing on how to open HD from casing. Was there any previous issues that could have lead to this?The dv2,3,4 series had an issue with the Graphics chip on the board where the soldering would become brittle and break away from the board. Usually this can be fixed by a very expensive reflowing JOB, but is not 100% guarranteed to work. Otherwise it is usually a MOTHERBOARD replacement, for which cost you could almost buy another laptop.
