=== 1. Check the Cable ===
We’ll start by checking your laptop cable. In the best-case scenario, you have another device compatible with your laptop charger or a spare charger handy. Plug the cable into another device. Is it charging? If it is, the battery or software is the problem. If the secondary device doesn’t charge, it’s either the wall outlet or the charger.
Now, let’s check the wall outlet. This is often an overlooked troubleshooting step, but it ensures that we aren’t getting a faulty reading from the previous test. It’s best to unplug an existing device (that is working properly) and plug in your charger. This ensures that the outlet is emitting electricity. If your laptop still doesn’t charge, it’s most certainly the cable.
=== Check the Battery ===
Checking the battery is a little more difficult than checking the charging cable. Especially if you can’t power your computer on or you don’t have a removable battery. But there are some key indicators that let you know your battery is going bad. Take note of any of the following issues:
* The battery is getting hot. Especially while charging.
* The battery seems to go dead faster than it did when you first purchased it. Sometimes this can be normal wear and tear, or you’re doing more on your laptop than you did before.
* Taking a long time to charge to 100%.
* The battery is swollen. Inspect the seams of your laptop for any bulging or separation.
If you do have a removable battery and a multimeter, you can use the multimeter to check the connection ports. However, you will also need to know the voltage rating on the battery too. This information will be available on the battery or the manufacturer’s website.
If you haven’t noticed any signs of [link|https://www.laptopbatteryshop.com.au/lenovo-thinkpad-t410.html|battery|new_window=true] failure and your charging cable passes the tests above, jump straight to step 2. Otherwise, read through the sections that correspond with your diagnosis to fix your laptop.
