My first post on these forums, I am looking for help with a specific problem. I have a Lenovo G40-30 laptop which does not boot up the BIOS. Pressing the BIOS button on the laptop and selecting the BIOS gives me a black screen with a still cursor in the top left hand corner. The only part of the BIOS I am able to enter is the boot selection.
I have Windows 8 running on the laptop, but I occassionally get a BSOD which is why I have been wanting to enter the BIOS and format everything and get a fresh, clean install.
My question is how can I reset the BIOS? I am unable to reset the CMOS battery because it is soldered onto the motherboard, unless taking it apart and re-soldering will reset it?
I am looking for any ideas/solutions to my problem.

Hi Akuto ,
Welcome to the Community Forums.
Depending on the model of your machine, initially best way to start is to perform power drain.
Turn off the pc and remove the battery and unplug the ac adapter charger .
Press down the power button down for 15 seconds.
If possible to remove the harddrive to prevent fast boot .
Place back the battery and charger.
Turn it back on using the Lenovo button and choose BIOS set up .
F9 should load defaults and F10 to save and exit.
Any BSOD without the harddrive?
Turn it back off and place back the harddrive .
Start back with the same Novo button for the BIOS set up and check if the harddrive is detected and restart .
It would be helpful to have the model and machine number so that we can check further but you may also refer to the user guide and hardware manual downloadable from the support site.
It would indicate the same process for a Factory reset for your machine accessible thru the same Novo Button.
System Recovery will delete everything on the PC and reimage it back the way it was from out of the box .
One Key Recovery from Inittial backup is the hidden factory partition on the same harddrive.
Update us how it goes.

Thank you for your reply. I did manage to get into the BIOS by removing the hard drive. I did not think of that before. I have since managed to install Windows and everything is running fine.
