been installed, you should follow the steps as
detailed below:
1. Turn off the computer.
2. Disconnect the AC adaptor and all peripheral
devices.
3. Remove the battery pack.
4. Remove the incompatible memory module.
5. Install the battery and/or connect the AC
adaptor.

If you are still unable to resolve the problem,
contact your reseller, dealer or service provider.
Remove the memory module from Slot B and
insert it into Slot A.
