How to adjust brightness on P-6860fx besides fn keys

My gfx card RAM died on my a couple of days ago after playing left 4 dead 2 and seeing red bars on my screen. My laptop still works, it's just that because the video Ram went bye-bye and can't do crap about it except by a new pc, the laptop barely knows the gfx card is there anymore and hence can't install the drivers, and i get this: Diagnose video card problems by comparing with example corrupted screens(look at first picture) Except it's little blue bars most of the time, and red when the gfx is being used more.
Because the drivers can't be installed, my fn brightness keys are stuck and I can't use an external monitor. So until I get a *DESKTOP* (that I'll build), i need to know how else can you adjust the brightness through windows maybe? Cause my eyes are hurting a bit now.

PS: Funny how most of the recent post about this laptop and other versions have to do mainly w/ the gfx card failing, if not dying on them. It sucks that they attach the gpu to the motherboard so if the gpu dies all of us have to get a whole new laptop rather than simply replace the gpu.

Srry if this all seems rash it's just my 2 last laptops were gateway, the first was really slow (ati xpress 200m, yuck!) and had BSOD's from memory (no matter what sticks I used), and this second one was beautifully fast for the time, but always seemed to have gpu problems, and had a hard drive failure and had to replace that recently.

 

I don't think there is any other way. I used my 6860 with a dead gpu for 1 day and could not stand the dim screen. Luckily I had the best buy warranty on mine and they gave me a G73 in exchange for my dead gateway.

 

I don't understand your problem but you can adjust the brightness in Windows in the power settings.

 

Nope I didn't even have that option when the GPU was dead.

 

Yep I don't have the ability to adjust brightness at all anywhere which sucks

 

Damn I think my warranty ran out, as it only good for 2 years, and it's past that. Doesn't matter though, I'd rather get a desktop 4 my needs at this point. But I'll always miss this laptop. To bad it went only after 2 years .
