The CPU unfortunately is not in a socket, but rather soldered directly to the motherboard.

To replace the hard drive, you must remove the seven screws in the battery door, the 14 screws that hold the whole back cover on, and one more silver screw inside the battery compartment in the center of the tablet. Remove the back cover (this may require you to unplug and remove the bluetooth and 802.11 cards, if so equipped). Flip the back cover over and you will see the hard drive cage. It has 4 screws. remove them and flop the cage off to the side and then you can pull the hard drive.

We had some problems with certain 512MB PC133 SoDimms, I think the issue had to do with the density of the chips .

here is some information from the Unigen datasheet - 512M Bytes (64M x 64 bits), PC133 SDRAM Unbuffered SODIMM, based on 8 pcs 32M x 16 SDRAM with LVTTL, 4 banks & 8K Refresh

I can supply you with the parts you desire. please private message me your e-mail address and I will supply you with a formal quote.

Thanks!
