I always keep my laptop plugged in to the AC adapter, because it doesn't work on battery power anymore, but lately my laptop won't stay on. It stays on for like, 15-30 minutes and then just shuts off. I check the AC adapter every time this happens, and it's always still plugged into the outlet and the laptop.

First, try charging the battery as you usually do. After that, remove the battery and try using your laptop. Take notice of the results.

If you were able to use the laptop, there's no problem with the charger. Otherwise, there was a power outage while you tried using it or the charger doesn't work. You figure that out.

After that, put the battery in and unplug the charger. Try using your laptop. Take notice of the results.

What kind of battery do I need for my laptop?

Look on the underside of the laptop.

The Lenovo laptops usually have got a sticker with the model number.

You see a code that says "Type" which is usually in the following format:

XXXX-XXX

When you go onto the Lenovo web site, you'll need this information.

First they'll ask you what it is.

So under Brand choose "Notebooks and Handhelds"

Type should be written on the laptop front, near the screen. I think it is written top right of the screen on most of them.

Then under "Type" choose the first part 4 digit part of the code, found on the sticker.

Then under "Model" choose the second 3 digit part of the code, found on the sticker.



Here is where you can find your model number:

Most of the newer laptops are in the 3000 series. The older laptops are in the Thinkpad series (before Lenovo bought IBM).



As for searching for a battery, you can usually type the 7 digit code from the sticker straight into the Google search engine.

So for example you could type this into Google:

Lenovo 0761-25S Battery

To find a battery for your Lenovo.
