Solution: The battery power is getting low. Connect the ac adapter to the computer, or replace the battery with a fully charged one.

Problem: When you take action to return from standby mode, the computer display remains blank.

Solution: Check whether an external monitor was disconnected while the computer was in standby mode. Do not disconnect the external monitor while the computer is in standby mode or hibernation mode. If no external monitor is attached when the computer resumes, the computer display remains blank and output is not displayed. This restriction does not depend on the resolution value. Press Fn+F7 to bring up the computer display.

Problem: The computer does not return from standby mode, or the standby indicator stays on and the computer does not work.

Solution: If the system does not return from standby mode, it may have entered standby or hibernation mode automatically because the battery is depleted. Check the standby indicator.

vIf the standby indicator is on, your computer is in standby mode. Connect the ac adapter to the computer; then press Fn.

vIf the standby indicator is off, your computer is in hibernation mode or power-off state. Connect the ac adapter to the computer; then press power button to resume operation.

If the system still does not return from standby mode, your system may stop responding and you cannot turn off the computer. In this case, you need to reset the computer. If you have not saved your data, it may be lost. To reset the computer, press and hold the power button for 4 seconds or more. If the system is still not reset, remove the ac adapter and the battery.

The R40 is notable for its combination of performance, reliability, and mobility, making it an attractive choice for those seeking a dependable mobile computing solution.

One of the standout features of the R40 is its sturdy design, which embodies the ThinkPad philosophy of durability and ergonomics. The laptop has a classic black chassis made from high-quality plastic and reinforced with magnesium alloy, providing resistance against everyday wear and tear.
