At my company we have a HP Elitebook 8770w with Windows 7 OS that from time to time doesn't manage to boot like it should do. The SSD has been replaced with a new one but still does this problem occur. To start troubleshooting, do I want to enter the BIOS, but it's been locked with a password that I don't know because the previous IT'er put it there and doesn't know it either.
At this moment it boots perfectly without any problems. But maybe next week it won't boot anymore. I tried to boot with a dockingstation, without battery, with an other monitor, ... but all these don't work either. When it boots, do I hear a drive turning on, (altough should an SSD be silent) the keyboard lits up, the screen lits up, but shows a dark grey screen and that's it.
If the computer manages to boot, I press
F10 to enter the BIOS setup but then it asks for a password which is unknown by us. We tried some standard passwords but none was correct. After 3 attempts it shows an on screen keyboard. After the 4th attempt I'm locked out and have to reboot. I've also tried to boot without the CMOS battery, but still can't enter the BIOS setup.
I've been running the System Diagnostics.
- Memory Test was a succes and no problems occured
- Hard Disk Test:
Quick Test: SMART check and short DST test were a succes and no problems occured.
Optimized test: SMART Check was a succes and no problems occured. BUT the Long DST test freezes at 99% with 1 second remaining.
This happend twice now, so I assume something is going wrong here. Because it's freezing, it doesn't give back any errors or problems that might have been found.
