Advent 5431 turns off and on every one minute

January 31, 2011 at 05:12:34
Specs: Windows vista, PENTIUM DUAL CORE
My laptop would not display until i try to close the lid cover, then it will display. So i decided to check if the problem is the inverter or the backlight by removing the cover of the base. After that it started shutting down on and off by itself at every 1 minute.

Any help please........?

If the wiring between the video adapter and the built in display is damaged, the symptoms you have are possible, and symptoms may vary depending on what position the lid is in.

Laptop no video (or video problems), and battery, AC adapter, power jack T shooting.

See response 1:

DO NOT plug in or unplug a monitor's video cable into / from a video port while the computer is running. Doing so can damage the monitor's circuits and/or the video adapter's circuits.

Some laptops will display on an external monitor without you having to do anything.

If you get no video on an external monitor, some laptops have a key combo that you must press to toggle the display to external video only / built in display video only / sometimes both - see the Owner's or User's manual for the model.
