Replace the battery

Notice

Fire and explosion hazard

There is a risk of fire and explosion if the battery is short-circuited.

  • Use insulated, non-conductive tools if you cannot grip the battery with your fingers and ensure correct polarity when changing the battery.

The battery must be replaced every 5 years. Replace the battery with a CR2032 battery (3 V, 225 mAh). The battery compartment is below the front flap.

The battery powers the built-in clock and thus buffers the time and date. The time and date are displayed incorrectly if the battery is empty or the battery is removed. Be aware of this behavior for your hardware and software configuration and reset the time and date in the BIOS after a battery change. If the operating system receives the time from an NTP server, the time and date can be set via the operating system.

Requirements:

Replace the battery as follows:

1. Open the front flap with a spatula or screwdriver.
Replace the battery 1:
2. Push the side flap to the left.
Replace the battery 2:
3. Carefully lever the battery out of the bracket with a plastic spatula.
Replace the battery 3:
4. Push the new battery into the battery compartment. The positive pole points to the left towards the DVI interface.
The battery change is complete. Close the side and front flaps and reset the date and time in the BIOS.
To dispose of the battery, remove it, stick insulating tape over the poles and take it to the local battery recycling.
