HP Support is FANTASTIC! I bought my HP in October 2004 and have loved it every single day. When my power cord frayed at the end right before the connection I called them, and got an English speaking associate in the US!, explained the problem and the next day I had a brand new power adapter with a call tag to send in the old one. Cost to me? $0!
A few months later I was having some issues with the battery not charging properly. Turns out where the male power prong on the mother board was bad, again I called them, got an English speaking associate and explained what was going on. They sent me a call tag to have my laptop go back to their plant in CA (I had to supply a box though) and then they called UPS to let them know it was ready for pickup. I sent it on a Monday and thought it might be 2 weeks before I saw it again. They called me the next day to tell me they received it and that the issue was non-warranty work and I would need to buy a new motherboard.

I talked to a few folks there and explained to them that it could not possibly be a non-warranty issue as I take VERY good care of this laptop and the only way what they are saying could happen is if someone yanked the cord out very hard. They re-inspected the piece, called me back and agreed that I was right. Turns out a bad solder job was to blame, they had it fixed that day and I had my laptop back by Thursday including a very nice cleaning job of the keypad and screen.
I have had very good success with HP's customer service dept as well as their ordering dept when I have bought new pieces for the laptop. I know some folks dog them for their ties to Compaq but I cannot complain.
