My Notebook Touch Pad not working

[MeNeedHelpPlz]

Hey there

so I have this "HP 241 G1 Notebook" for quite a years, worked all those years and i quite changed it a lot since then.

I m a average tech person so i upgrade its OS quite often.

but from a month or so its touch pad stopped working. i searched a lot for solution but didn't find one.

(my other external mouse works perfectly)

But on one forum they suggested that upgrading/restoring a bios helped one person with same problem, so i wanted to try that out, and i know it can be hardware problem but i wanna do all i can by software wise.

But the problem is that i changed its partitions quite a few times so there are no original partitions like HP tools etc.

and i don't even know that my laptop came with these partitions or not by default,

I changed the disk to MBR for linux installations but i saw bios upgrade video and they were all for UEFI so 

i changed back my disk to GTP, but there is no graphical bios interface so how can i get that?

i want to know that can i restore or upgrade my bios?  i can share screenshots if needed plz help.
