Description	Viking P/N
16MB SDRAM Memory Module	I0293, RI0293
32MB SDRAM Memory Module	I0294, RI0294
64MB SDRAM Memory Module	I0295, RI0295

†Requires removal of the standard memory module.

††Installing the I0296, RI0296 for configurations above 160MB will require the ACP patch version 1.0 for ThinkPad 770 and 770E from IBM. The Pentium MMX machines are upgradeable to 256MB maximum, but the Pentium II machines are upgradeable to 288MB maximum.

4.Locate the two memory expansion slots in the open compartment. Also notice the location of the off-center key on each of the expansion slots. Depending on the model of your computer, there may be a standard memory module occupying one of the slots. If your system has a mod- ule occupying one of the slots and you wish to expand your system to its maximum amount of memory, the standard memory module will need to be removed and then replaced with a higher capacity module. If you do not need to remove a memo- ry module at this time, please pro- ceed to step 6.

6.To install a memory module, insert the module into the expan- sion slot at an angle and then push it down until it clicks into place. To be certain that the module is installed correctly, ensure that the off-center notch on the module is aligned with the off-center key of the expansion slot. The module can only be installed one way due to the position of the notch.

3.Locate the memory expan- sion cover on the right side of the bottom panel. Also locate its single holding screw. Use a small Phillips screwdriver to remove the holding screw. Then remove the cover by lift- ing it to the right.

5.To remove a memory mod- ule, locate the retaining clips on both sides of the memory mod- ule. Gently pull both clips away from the module, then lift the module out of its expansion slot.

Caution:

Electro Static Discharge (ESD) can damage electronic components. Before touching the memory module, ensure that you are discharged of static elec- tricity by touching a grounded metal object.

INSTALLATION INSTRUCTIONS:

1.Turn the computer off and disconnect the AC power supply and any other cables from the unit.

Note: If the unit appears to be powered down, ensure that it is not in Suspend mode.

Note: For optimum performance, install the largest capacity memo- ry module into the top expansion slot.

7.Replace the memory expansion cover and be sure to secure its holding screw.

8.Insert the battery back into its compartment and turn the system right- side up.

9.Replace the AC power supply and any other cables you may have dis- connected.

10.Open the display screen and turn the system on. The computer will automatically reconfigure itself to recognize the additional memory. The new memory can be verified during the POST routine at start-up and at the SETUP utility.

The installation is now complete.
