Solving Problems: Dell Inspiron 8200

Check the AC adapter— Check the AC adapter cable connections. If the AC adapter has

a light, ensure that the light is on.

Connect the computer directly to an electrical outlet— Bypass power protection

devices, power strips, and the extension cable to verify that the computer turns on.

Eliminate possible interference— Turn off nearby fans, fluorescent lights, halogen

lamps, or other appliances.

Adjust the Power Properties— See the Tell Me How help file or search for the keyword

standby in the Help and Support Center. To access the help file, see "

Accessing Help."

Reseat the memory modules— If the computer power light turns on but the display

remains blank, reseat the memory modules.

Ensuring Sufficient Power for Your Computer

Your computer’s Intel® Mobile Pentium®4 microprocessor requires more power than the

microprocessors used in Dell’s earlier portable computers. Your computer is designed to use the 90-W

AC adapter and the 4400-mAh battery that shipped with it; for optimum system performance, you

should always use these components.

The 70-W AC adapters used in some of Dell’s earlier portable computers can be used with your

computer, but they will decrease system performance. Likewise, you can use the 3800-mAh and 3600-

mAh batteries from earlier Dell computers, but these lesser-capacity batteries will discharge faster.

Using less-powerful AC adapters or batteries may cause you to receive a WARNING or a SYSTEM

CONFIGURATION ERROR message similar to the following:

WARNING: 70 Watt AC adapter detected. System will not be capable of running in full

performance without a 90 Watt AC adapter.

NOTICE: Do not use an AC adapter rated under 70 W or a battery rated under 3600 mAh in

this computer. To do so will cause indeterminate results, including data loss and/or immediate

system shutdown. Using one of these lower-powered components will cause a SYSTEM

CONFIGURATION ERROR message to appear.

Docking Power Considerations

HINT: If you want to upgrade the AC adapter for an existing Dell docking device, you can

purchase an additional 90-W AC adapter from Dell.

The 4400-mAh battery supplied with the computer is not designed to support both the computer and a

docking device. For optimum system performance, always use the 90-W AC adapter (with or without a

battery installed) when using the computer in a docking device. You can identify the 90-W adapter by

the lighter-gray tip on the connector that plugs into the computer or docking device.

Using a 70-W AC adapter will cause the computer to run in reduced-performance mode and may
