Because the computer is so new (and still under warranty) 'only 2 months old'; take the unit back to DELL and have them install the much needed update, this way if the update kills the computer, it's their fault not yours...and ultimately they will have to deal with it.
I purchased a Studio 15 and it came with a bug. It shuts down all on it's own at odd intervals. Checked with the Dell site and they say that it needs a bios update. Well, they give instructions on the site for doing this(I have already downloaded the bios update), but everything I know says 'Don't touch the bios," so I'm afraid to do what they tell me to do and I wonder if they shouldn't fix it anyway as it is a new machine. They warrantee only hardware...not software and I think this would qualify as a software issue...right?
Still, they sent me a laptop with a bug in it which shouldn't BE!! Out of the box, it didnt' work right!! Of course, I put off dealing iwth it, so now the laptop is 2 months old (I've been just turning it back on when it dies.) and i'd like to fix it!! HELP!!
