Here's what is going on:
I bought an HP Pavilion ze4420 yesterday and installed WinXP Pro on it. I updated the drivers and critical updates through windows update and all was fine. This whole time I was on AC power so as not to die in the middle of it. When I get all that stuff installed, I decided to go on battery power and see how long it lasts. (Yes, I know about cycling the battery)
The problem is that when I'm on battery power, there seems to be what the techsupport person called an electronic scraping, I call it beeping. Anyway, this beeping sound only occurs when I am running on battery power. It tends to be soft, but frequent, as in more than one distinct beep per second. Sometimes there are many seconds between these beeps. But what puzzles me is that it only occurs when on battery power, and not on AC. It does tend to somehow corelate with activity... such as when I move the mouse, it beeps faster.
What I've done to "correct" it:
First I tried muting speakers. Its not coming out of the external speakers. I tried muting PC speaker (but it doesn't sound like the PC speaker and NO ITS NOT THE HARDDRIVE either )
disabled anything audio related
I've upgraded to latest bios
Cycled battery
Updated all drivers/software from HP's site.
HP's last recommendation is to get out the restore disks and restore it to original factory condition. This wastes all my previous efforts. I haven't done this yet, and wish to avoid it at all costs. (i hate the crap that comes pre-loaded).
Any help would be appreciated
