IBM THINKPAD R40 - Manual (Page 8)

8. Replace the memory slot cover over the memory slot, aligning the back side of the cover first; then tighten the screw.
Attention: When you have added or upgraded a memory card, do not use your computer until you have closed the memory
slot cover. Never use the computer with the cover open.
9. Put the battery pack in place and turn the computer over again.
To make sure that the SO-DIMM is installed correctly, do as follows:
1. Turn the computer on.
2. While the “To interrupt normal startup, press the blue Access IBM button” message is displayed at the lower-left area of the
screen, press the Access IBM button. The Access IBM Predesktop Area appears on the screen. (If you have deleted the service
partition of the hard disk drive, or replaced the hard disk drive itself, the Access IBM does not appear. Refer to the “Note”
below.) Next, double-click the “Start setup utility” icon. The IBM BIOS Setup Utility screen appears. The “Installed memory”
item shows the total amount of memory installed in your computer. For example, if you install a 256 MB SO-DIMM into a
computer whose built-in memory is 256 MB, the quantity shown in “Installed memory” should be 512 MB.
Note: If the “Startup Interrupt Menu” appears instead of the “Access IBM Predesktop Area”, press F1 key to enter the “IBM
BIOS Setup Utility”.
