Hp 4545s Bios Dump
Hp 4545s Review

Solved: Product HP ProBook 4545s OS Windows 7 64bit Hi All, When trying to access the BIOS on the HP Probook 4545s it is asking for a password. - 6350164 - 3.

My bet: when you phone HP with your UUID it gets added to a database of allowable UUID's of machines where the BIOS password can be reset. I suspect the boot process contacts those HP servers, using the ip addresses from the smb.bin, passing the UUID.

The BIOS is unlike any BIOS I've seen before. It's a mouse-using GUI instead of the classic arrow-key blue screen funny font menus. Also unlike others, the Esc key is used to access it, instead of Del.

Last night I downloaded the BIOS update setup sp57752 - HP Notebook System BIOS Update for my HP Probook 4520s laptop. During the installation, when the software was displaying something like writing block 400 / 640. the power malfunctioned and the laptop turned off. (The battery was very low and my UPS was not working). Anyways, right then I knew the laptop was bricked. I restarted the laptop and this is what happens.

The display stays off.
The CAPSLOCK key light keeps blinking.
The power button doesnt do anything, even if held down for 30 seconds or more. The only way to power off is to disconnect the battery and the charging cable.

I know I'd most probably need to take the laptop to HP customer care. But I was wondering if there was ANYTHING I could do myself to fix this issue. I know how to disassemble the laptop. I know how to take out the RTC battery. I wanna know if it'll be sufficient. Or will it require special hardware cables / serial ports / etc and proprietry procedures that only an HP technician will be able to perform.

Taking out the RTC battery which powers the RealTimeClock will not help. That battery powers the real time clock and the volatile par
