A quick search shows it's a relatively common Dell issue. No definite solution but the general consensus is that you need to get a genuine adapter. And it's apparently not OS-specific, the issue was reported to replicate in Linux as well.

Give him a charger to test with to prove it's the problem.

Hello Listers,

My colleague has a Dell Inspiron with an usual behavior.

The Mouse and Trackpad works fine while battery.

The moment he plugs in the AC adapter, the mouse and the Trackpad fails.

A reboot is normally the first troubleshooting step which doesn't solve this issue.

When he unplugs the AC adapter the mouse and Trackpad works fine.

Anyone who is facing the same problem?

How did you go about it?

Eric.
