Colleague's computer changes the battery, after power down, cannot start, because the BIOS date is changed back to the default time and the default setting. The hard drive is an SSD and the system is Win7. Win7 just start to enter the blue screen, and constantly restart. Tried the safe mode, the last time the configuration of the correct start is useless, and then I think to see the blue screen prompts, then power on press F8, select the last item: the system fails to restart automatically after startup, and then the blue screen information came out, the error code is 0x0000007b, online check a bit, The hint is that the hard disk mode needs to change from Achi to comatible, so it suddenly dawned, because this machine later changed SSD hard drive, need compatibility mode to work. After the drop point, the BIOS's hard disk settings become the default, so enter the BIOS to re-modify the compatibility mode, and then start the OK.
