A few questions about my dv2500t

I've had this thing for about 1.5 months, and finally have gotten around to asking a few questions. If these have been covered, I apologize... I did try searching.

I love this computer, except for a few issues (mostly minor). #1 is serious enough that I wish I could send it back, but I'm past the 21 days allowed.

1) On battery power, it makes that annoying high pitched buzzing sound. I can't hear it with any noise in the room, but in silence it drives me crazy. I tried playing with the BIOS feature that is supposed to remedy this issue, and it didn't do jack. Is there any other way to prevent this? I spoke to HP and they suggested the BIOS feature that was worthless.

2) My battery monitor doesn't give the time remaining, only the %age. Is there any way to get this?

3) The media buttons on the top only work when the program (i.e. itunes) is in the front. Is there any way to make these function even if itunes, or whatever program is playing media, isn't in the foreground?

Thanks!

 

the battery can't be changed for showing time - and i know, it sux, when i owned it it really bothered me because i came from a laptop that told me the xact time left

and thats not normal for the battery sound, i would send it in for repair

dont know about the last one
