BIOS cannot be restarted to Default

[GSE_sba]

Hi guys, (I am beginner so please I ask for patience)

 

I a just wanna tell you that I'd need a little help with an issue that I ran into 2 days ago:

 

I've got this FUJITSU CELSIUS M720 and it's been working excellent. Until at one point I wanted to install a new Harddrive (ssd card with a PCI adaptor), I went into the BIOS to sort of enable the PCI and I enable them all (that was stupid) and changed another settings from the PCI in order to enable the Harddrive (I cannot remember exactly what tho). And now after I have done that, the PC doesn't boot correctly and I get the FUJITSU screen with numbers and letters on the low right corner.

 

Now the real issue is that I have tried to reset the BIOS to the default by removing the battery for like 30 - 60 min and sadly doesn't make any changes, also I tried to locate the CMOS jumpers and adjust them in order to get it reset, but also that did not work. I have ordered some new batteries to see if I can get it to restart this time.

 

Anyways I am coming to you for help, if you have any peace of info that I can try please let me know. I would appreciate it.

 

Best Wishes

If you are seeing the Fujistsu screen I think you just have the wrong boot device selected.  Does pressing F12 repeatedly while the system boots get you back to bios?

Hi, that is also the Problem i forgot to mention. By either pressing F2 or F12 it does not set me to the BIOS menu.

Got it.  If you disconnect all of the drives, does that work?

Hi, I have tried that and it doesn't work at all....... the most annoying bit is that I tried repeatedly pressing F2/F12 and it doesn't work, then the Fujitsu screen is gone and I have now a black screen with a line.......

Does it always say code B2 at the bottom of the screen?

Try making a usb flash drive with a bios store in it. Also try disconnecting all the drives and  check whether this bio is showing or not
