Hello, this will be long, so please bear with me.
A few weeks ago on my brand new HP EliteBook 8730w I noticed a strange thing happening. When starting up the computer on battery power, it would freeze on the Starting Windows screen. On Battery power, I could boot into Safe Mode, and Safe Mode With Networking just fine, just not normal mode.
I haven't installed any new hardware.
I narrowed it down to the fact that when I connected the AC power, it would not freeze on that start screen. Fine, new motherboard right? WRONG!
Replaced motherboard, and right in front of the tech's eyes, it did the same thing.
Sent it back, they determined the RAM was bad.
I got it back, and it worked for about a week and then bam! Started happening again.
This morning, I restarted my computer FIVE TIMES in a row on battery power and the same original issue occurred.
I then unplugged all USB devices and tried them one by one.
Keyboard checked out, and then the mouse checked out just fine.
So for now it's booting properly, but I wondered if
A. Has anyone else experienced this problem?
B. What in sam hill could it be?
I called my service guys and they as a last resort are going to change the proc, but I told them that if this is a recurring issue, I think that it's just a defective computer. Could be the wiring, etc. Who knows!
We have other Elitebooks and this is the only one screwing up.
Edit: Oh yeah, it's not the power supply or the battery, those were eliminated early on. And it's not the RAM.
