Checking Connections
Loose or improperly connected cables are likely sources
of problems for your computer, external monitor, or other
peripherals (such as a printer, external keyboard, or
mouse). A quick check of all cable connections can easily
solve these problems. If the connector has two small
screws, make sure the screws are tight. In addition, check
for damaged or frayed cables, and for bent pins on
connectors.
Be sure the following items are properly connected or
installed:
• The AC adapter and the AC power cable
