3.Inspect the AC adapter.
Check for any physical damage, and ensure the power cable is firmly attached to the adapter brick and the system.

4.Verify the AC power source is working by attaching another device to the outlet.

5.Remove the Value Line notebook from any docking station or port replicator.

6.Remove all devices and then test for system power with minimal devices attached.

Notes:
■Although the hard drive can be upgraded, it is not designed to be removed and reinserted on a regular basis. Repeated and frequent removal, for purposes other than to upgrade for greater capacity or problem determination, can cause damage to the system.
