Hi. I'm trying to fix my friends laptop. It is a Toshiba Qosmio x875-Q7380. I entered the computers info. in my profile where my computer information goes. He upgraded his OS to Windows 10 about 6 months ago and hasn't had any trouble with it.
The computer turns on but wont boot up. I originally thought the RTC battery was bad and replaced it. I am doubting that is the problem now, but I need to follow through with my current repair before I explore any other troubleshooting options.
My question is that now that I have installed the new RTC battery the computer still won't boot. I've read online that in certain cases the BIOS software needs to be installed after changing the battery. Is this true? If so, how would I make the computer accept and install the software if I can't change the boot order?
I also read something about resetting the CMOS which just seems insane to me, and I'm not willing to try, so I really hope that I don't have to do that in order to fix it.
Thank you for taking the time to read this. Thank you in advance for any help you might give me.
