HP TC4400 tablet BIOS problem
I have a HP TC4400 tablet that I purchased used...The previous owner installed a trial of Windows 7 and supposedly put a BIOS password on it then forgot what it was...What the truth is, only he knows.
The unit boots no problem but I need to be able to boot from a CD to roll back and start over as this unit does not like Windows 7. Problem is I can't get into the BIOS...If I hit F9 I get the option to boot from the HDD or USB CD but it wont, so......
So in my former life I was a laptop tech and thought no problem. Took the unit apart and pulled the CMOS out and left it for a good 3 hours. Put it all back together and now it gives a date/time error during POST but the password lock is still there.
I have searched high and low on the internet and HP and can't find a solution. Any wisdom or advice would be greatly appreciated.
Thanks in advance!
