Windows 10: How to reset the BIOS settings if there's no CMOS battery or jumper?
How to reset the BIOS settings if there's no CMOS battery or jumper?
So, I have this friend who messed up the BIOS settings on his Acer Aspire 5745G and now the laptop turns on but it's just a black screen. He said that he switched from his onboard video to his discreet video card and that's when the problem occurred. I know I can just remove the CMOS battery or short the 3 pin jumper with something metal to reset the BIOS settings but the problem is that I can't find either of these. It's really strange, I even brought out the whole motherboard and I still couldn't find it. I think I read somewhere there's a another way of resetting the settings but I can't remember it. Any help on this?
This may help, from Google:Reset Acer Aspire 5745g Bios - YouTube
I'm sorry but that doesn't help at all. I said there's just a black screen, nothing can be seen.
Did you see the instructions below the video to use f2 to enter bios, then f9 to set defaults and f10 to save the defaults. You don't need to see a display to accomplish that.
Oh, my bad. I didn't look at the description and I wasn't even paying attention to what he was saying. I'll try this tomorrow with my friend. It's the same laptop so hopefully it'll work. Thanks!
Many laptops/tablets hide or eliminate the BIOS reset jumper. It's not there or not marked as such. Not like it is on a desktop PC. Mainly to prevent a thief from easily resetting the BIOS/Boot password and getting access. Even removing the BIOS battery will prevent those settings from being reset. Other settings like boot order etc will be returned to defaults though when you remove the CMOS battery. Every laptop I've disassembled has had a CMOS battery, Usually its several batteries in a pack to prolong their effective life. Replacing them can be a real PITA.

Accessing and removing the CMOS battery is simple if the laptop is like this one.
....according to clock on task bar the time is wrong. I know this has probably been covered before, but late in my life I find it difficult at times to find the correct old thread with the answer. Please direct and help me.
Can anybody explain these settings in bios?
I dont really understand how these settings work.
I just replaced my CMOS battery. The system rebooted and all my Windows 10 files are gone, it's created a new drive N: but I couldn't restore from Command line and I have a semi useless Windows 8 in place. Help?
Is there a default in set up after replacing the cmos battery or should you take a picture with the flash off just in case?
I cannot think of any other way to know the information as print screen etc cannot be used.
