Solving Problems: Dell Inspiron 4100

Check the battery— If you are using a battery to power your computer, the battery charge may be depleted. Connect the computer to an electrical outlet using the AC adapter, and turn on the computer.

Test the electrical outlet— Ensure that the electrical outlet is working by testing it with another device, such as a lamp. If the device is plugged into a surge protector, try plugging it directly into an electrical outlet.

Check the AC adapter— Check the AC adapter cable connections. If the AC adapter has a light, ensure that it 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.

Adjust the Power Properties— Search for the keyword standby in Windows Help. See "Accessing Help Files."

Switch the video image— If your computer is attached to an external monitor, press to switch the video image to the display.

If the display is difficult to read

Adjust the brightness— Press to increase the brightness, or press to decrease the brightness.

Move the subwoofer away from the computer or monitor If your external speaker system includes a subwoofer, ensure that the subwoofer is at least 60 cm (2 ft) away from the computer or external monitor.

Eliminate possible interference— Turn off nearby fans, fluorescent lights, halogen lamps, or other appliances.

Rotate the computer to face a different direction— Eliminate sunlight glare, which can cause poor picture quality.
