IBM/Lenovo ThinkPad X41 Tablet
Construction: Upgrading and Maintenance
The display swings backwards on a 180 degree plane. It goes a few degrees lower if you use a 4 cell primary battery.
The X41 Tablet follows a simple layout. Removing the single bottom access pale gives way to reveal the unpopulated DDR2 SODIMM memory bank, miniPCI slot populated by the WiFi card, and the Bluetooth module. The sample we have here came populated with one embedded Hynix 512MB DDR2 533/PC4200 memory module, so the maximum memory capacity of the system is 1.5GB, even though the chipset supports 2GB.
The hard drive doesn't use a swing door design, so you can only remove the hard drive by tugging the enclosure door open. Unlike the T and R series, the display lid doesn't need to be opened to the hard drive in order to avoid damage to the casing. However, you must remove the digitizer pen before you remove the hard drive.
Like the previous IBM designs, you can easily access the keyboard by first removing the four keyboard screws marked by the "keyboard icon" on the bottom of the notebook. Since the keyboard uses a simple interlocking mechanism to hold it in place, you just need to "scoot" the keyboard forward away from the touchpad and lift it out with a flat-head screwdriver. You can also do this with your fingers if you are careful, or carefully hold the notebook upside down and disengage the keyboard. The keyboard connector should just pop out on its own.
There is really nothing located below the keyboard to be worth any mention. The only reason to remove the keyboard is for cleaning.
