The AC adapter cord or the plug on the laptop end of it, or the power jack in the laptop, may be damaged.

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

See response 1:

"Product: Acer Aspire 7720g ac adapter - 19v - 90w - 4.74a - black - with multiple tips - (compatible)"

Make sure the polarity (+ and - ) of the plug is correct, and that the tip is making a good connection.

Use the tip with the smallest internal hole that will fit, otherwise the central pin in the jack may not have a good connection.

This information represents a basic troubleshooting guideline. Refer to your user guide for specific charging and connection instructions. Manuals may be available online in the Support Web site of Dell.

Remove the battery from the computer.
Confirm the battery contacts are free of any foreign material that may prevent charging.
Reinsert the battery into the computer.
Verify that the acer AC adapter cord is properly connected and plugged directly into a known working AC power outlet.
NOTE: If the battery charges correctly when the AC adapter is plugged directly into an AC power outlet, but not when plugged into a power strip or surge protector, the problem is with the power strip or surge protector and not the computer battery or AC adapter.

Verify the correct AC adapter is being used.
Ensure the AC adapter box power light is on. This will be an illuminated green light.
If the AC adapter power light is not on, the laptop AC adapter and power cord will need to be replaced.
Verify the charging indicator is illuminated on the computer.
If the issue still exists, install a different compatible Dell battery, if available.

NOTE: If a replacement battery charges and operates correctly, the problem is with the first battery.

If neither the original nor a replacement battery charges, service may be required for the computer.
