Hello, my laptop was being slow and I decided to instal linux, burned the iso on a USB drive, started my pc and started as linux from the flash drive.
after 30 seconds my laptop just turned off

I tried turning it back on, and it would turn off again after about 1 second.

I think I could just reset my bios

TLDR: I want to reset my bios but the CMOS battery is attached and I cannot find the battery jumpers or pins

The laptop is a DELL; vostro 3750 from 2011
(will provide with pictures)

Looks to me like the cmos battery sits under a ribbon cable in a black casing and attaches to the board by way of two wire connector. You should be able to disconnect it from the board by unplugging that connector and then reconnecting it after thirty seconds but it will require some disassembly to gain access. Again, your model could be slightly different than the one I looked at.

By attached, do you mean soldered to the board, or attached via two wires and a plug in. If it has a plug in, it can be disconnected. There are no jumpers that I'm aware of on that model.

If you remove the power cable and regular battery, press the power button for thirty seconds, it should reset the BIOS. This doesn't work for all models though so you might need to find a way to disconnect the cmos battery, if possible, to reset. I'll check into it a bit further and see if I can find the procedure. Knowing your full model number as printed on the case or in the battery compartment would be helpful as sub-models often have very different configurations.

Trying to upload pictures (phone is bad so i'm taking the best I can)
It seems to be soldered, the model is 3750 early 2011 (on the Dell website)
I'm not sure wich key you want because they are so many (will add once I can guess wich one you want)
