lenovo g550

i have lenovo g550 and the motherboard now is dead

this is not my problem because i can buy a new one but the problem here is because i set bios password for the hard and now can not connect the hard to any other laptop because it asks for the password if i installed it as a master hdd and when i enter the password it says that the password is incorrect but i'm sure that it is the same password because i use it since i bought the labtop since 2010 and now when i connect the hdd via usb it doesn't appear in partitions or in device manager and in disk management appears as an unallocated space

now i have to unlock this hdd and noway to repair the old motherboard because the vga chipset was damaged and i need all the data on the hdd how can i solve this problem?????

if i buy the same model for the motherboard can this fix the problem or the problem related for the old mother board and memory for the bios Smiley Sad 

please any hope to solve this?

Re: lenovo g550

Hi pulongyi,


Welcome to the Community Forums.


The master HDD password is coded with the BIOS of the original board and I do not see other possibility to unlock it with a dead board unless you sought help with data recovery centers.


Although costly as usual, they have other means of retrieving data out of the drive if this was your goal. You can also check with other service centers that may reball/ reflow the VGA chip to get the functionality of the board back.
