When transferring data to or from a flash memory card, such as an SD card, do not put your computer in sleep or hibernation mode before the data transfer is complete. To do so might cause damage to your data.

Cleaning the cover of your computer

Occasionally clean your computer as follows:

1 Prepare a mixture of a gentle kitchen-use detergent (one that does not contain abrasive powder or strong chemicals such as acid or alkaline). Use 5 parts water to 1 part detergent.

2 Absorb the diluted detergent into a sponge.

3 Squeeze excess liquid from the sponge.

4 Wipe the cover with the sponge, using a circular motion and taking care not to let any excess liquid drip.

5 Wipe the surface to remove the detergent.

6 Rinse the sponge with clean running water.

7 Wipe the cover with the clean sponge.

8 Wipe the surface again with a dry, soft lint-free cloth.
