due to: curiosity + HP + BIOS upgrade + Vista.
So for now I’m enjoying quite a computer-free life 
Scenario: preparing for a Vista tryout. One of the upgrades is for BIOS - going to F.28
After upgrading BIOS and installing Vista, a couple of times the computer froze and upon a hard restart, the nothing happened.Symptomps: upon powering up the laptop, the LEDs are turned on (weird enough the card reader LED stays on), the DVD-ROM spins, the HDD is initialized, but nothing more. The HP logo doesn’t appear.
Arbitrary recovery: the first time, after taking out the battery, and powering only by AC, the computer started OK. The second time, the trick didn’t do it.
Thoughts? Similar scenarios?
PS: I already tried reseating the RAM modules, did a power drain..
PS2: What’s even nicer is that Pavilions are not sold here, so in order to repair it (it still has warranty) I need to take it back to where I bought it!
