IBM ThinkPad X40 Series Service And Troubleshooting Manual page 43

The system does not enter hibernation mode from suspend mode if the
computer is not connected to an ac power source.
Solution:
The timer-wake-with-battery-operation is disabled by default. If you
enable this function, the computer could wake up and begin running
while it is being carried; this could lead to damage to the hard disk drive.
With this risk in mind, you can enable the timer-wake-with-battery-
operation.
1. Turn your computer off and then on again; then, while the message,
"To interrupt normal startup, press the blue Access IBM button" is
displayed at the lower left of the screen, press the Access IBM button.
IBM Rescue and Recovery screen opens.
2. Click Access BIOS. The System Restart Required window is displayed.
3. Click Yes. The computer restarts, and the IBM BIOS Setup Utility menu
appears.
4. With the cursor key, select Config; then press Enter. The Power
submenu is displayed.
5. Select Timer Wake with Battery Operation by pressing Enter.
6. With the F5 or F6 key, select Enabled; then press Enter.
7. Press F10 and Enter to save this setting and exit this utility.
For information about the BIOS Setup Utility, see "IBM BIOS Setup
Utility" in Access IBM, your on-board help system.
