HP 6735s- Blinking lights of certain peril!!!!

[lagnus]

My HP 6735s is flipping out(descriptive...). 

After coming back from work with my laptop, I push the power button and to my dismay all the lights just kept blinking(caps lock, cdrom drive light, cd rom drive motor, cdrom drive laser, hard drive amber light) except for the wireless and power button indicators. The cpu fan also just runs, and the cdrom is consistently looping through trying to read a disc which doesn't exist.

I am not sure what happened but I think my laptop is in a confused hardware state. Is there a way to do a hard reset or to verify that the bios is still responding to input on powering the machine? Is there a guide available for showing what all the blinking lights mean when they are shown in a particular combination, so that the system can be diagnosed ?

Cheers!

once these lights blinked, what's the status on the display panel?

black screen or hp logo display?

if possible, you can do a restore default in bios first!

Hi there,

I have the same problem with two hp printers i left in my mothers custody while overseas! Both of them when you turn them on just some of the lights flash and either nothing appears on the screen, or the other one the screen goes blue and then stays plain bue.

What do you mean by restore the bios first?

Thanks a bunch!
