I have connection problems with USB ports on my DV 1000 & want to replace. Does anyone know how to? I think 2 of them reside on the motherboard, but one is on the other side of the laptop. I really need a schematic of this unit.

NO! You will damage one or both computers. You really need to repair the laptop or ac adapter to correct the charging problem. The HP dv 1000 as well as the other HP entertainment laptops have had a lot of problems. Not charging just one of them. I would strongly suggest a professional repair of this laptop.
It sounds like the motherboard is causing the usb ports to malfunction by allowing power surges into the power input to the ports.You maybe should try a powered usb hub to power your hardware or you may face motherboard replacement
It will recognize the new drive if you were able to "migrate" your data from the old drive. If not, you can clean install by booting from an optical drive (changing your boot order at start-up) and using a new OS disk or your recovery disks. You might be able to perform a remote partition & format and install from one drive to the other with USB external enclosures for each drive and another computer (depending on the 100G drive's condition). I hope this helps.
1) plug YOUR power adapter into your friends hp dv1000, see if it turns on laptop.on. If yes, then u have one less problem. 2) to trouble shoot a laptop takes a lot of skill, stuff is very small, things could be damaged just by pulling the wrong way. you would HAVE TO BE very carefull. Look for the trouble shooting manual 1st. or find a good technical person.

I just fixed this problem on my dv1000. The problem I found was apparently the USB ports on lower right and left side only mounted on the mobo with light soldering and no soldering on the other side of mobo. Due to heat I guessed, they came loose. I opened the mobo (using guide from a pdf file on the net, sorry i forgot the exact guide but you can ask uncle google). I took the mobo out and resolder those two ports with plenty of solder from the top surface only of the mobo as I unable to access the other side. Now they work again like charm. The top right USB is different beast. It is on different card along with S-Video port and apparently in permanent damage.
