My Second Hand HCL Laptop BIOS is locked with a date of 04 November 2007
Any way to unlock it? (HCL Leaptop K21 - PDC, HCL Board - T12Rg-H, with American Megatrends Inc BIOS.
On restart, every time the Clock resets to 04-Nov-2007, 12.00PM, even after changing the date and time in the OS
Hiren CD is not helpful, it says that the password is stored in e3 chip. Can not be re-written
