HP Recommended
Product: Probook 6560b
Operating System: Microsoft Windows 7 (32-bit)

Updated BIOS with latest update sp79709.exe VERSION: F.65 REV: A PASS: 1 , from Windows 7 Enterprise 32-bit. Upgrade went smooth, at the end got the Restart Computer screen,  pressed restart. 

 

symptoms: PC shuts down,  stays off. When pressing the power button the power button led flashes for a second as well as the led indicators above keyboard then turns off. Front led indicator go through the 4 leds then turns off. Fan spins for a second then stops.  Laptop completely dead. No beeps, no lights, no sound. Nothing. 

 

Things I've tried, with no results:

 

1. Hard reset, battery out, hold power button for more than 30 seconds, ac in,  press power button

2. Recover BIOS from hdd by holding Windows Button + B than pressing Power for 2-3 secs, also Win key+V and Win key + All arrows together

3. Recover BIOS by USB BIOS recovery flash drive + all methods from 2.

4. Remove CMOS battery for few hours

5. Start computer without CMOS battery

6. Unplug everything I could ,including RAM, pc fan, dvd, network card, hdd, battery. plug ac and start

 

 

please advise
