AC adapters: how long do AC adapter for IBM thinkpads last? when do you replace it?

Question

my IBM T42 sometimes just immediately shuts off. the geek squad said its either my AC adapter or battery. my battery holds a charge just fine so it must be the AC adapter right.

how long do AC adapters last? did you ever replace an AC adapter?

Answer 1

they go bad...just like any part on a pc.

If it's under warranty get it replaced. However, some mfgs only warranty a power adapter for 1year...like batteries.

That said, if your laptop shuts off, right click on your desktop and select properties. Go to screen saver, then click on the power button. Then go into the tab that has the drop down menus for when the pc is running on either power or battery. On AC power I set all three to never.

Also, check the tab that has something like "When I close the lid..." I set mine to "Do nothing" as I sometimes need to walk from place to place...
