Tips on How to Fix Your Laptop Battery
1. Recondition Your Battery
Most people usually wonder why do laptop batteries die? The answer is quite simple. The ability to recharge the laptop battery is the primary reason why the batteries die. Over time, the battery loses its ability to hold charge. As a result, the performance tends to deteriorate.
Reconditioning is practically one of the best ways for you to fix a dead laptop battery. It can help bring your battery back to life and perform as good as new. Here is how to recondition your battery.
i. Plug in the laptop into a power outlet while the battery is still inserted. Allow it to charge to 100%.
ii. Proceed to disable hibernation in the Power Options section.
iii. Navigate to the control panel and click on the Performance and Maintenance section. Open the Power Options and head to Power Schemes.
iv. On this menu, set all the six options to never, save, and disable power management.
v. You can then unplug the laptop but don’t switch it off. Use your computer till the battery is fully drained. Then recharge it and restart your computer. You can enable hibernation and go back to using your original power performance setting.
Reconditioning is mostly suitable for NiMH and NiCad types of batteries. This shouldn’t be tried out on Lithium-ion batteries.
2. Get a Cooling Pad for Your Laptop
Over time, most laptops tend to get too hot. This can have adverse effects on your battery. Heating up is amongst the leading cause of battery damage. Cooling your computer does an excellent job at reviving lithium-ion laptop batteries. Investing in a quality heating pad can do wonders for your laptop battery. It is a sure way of increasing laptop battery size. If you were wondering how to repair your Li-ion battery, then cooling it will do the trick.
3. Recalibrate Your Battery
Battery recalibration isn’t ideal for new batteries. However, most cases of dying batteries usually affect old batteries. Therefore, if your laptop battery has been ‘there’ for a while, it can benefit immensely from a recalibration. Laptop battery recalibration is necessary when the OS can’t figure out how much battery capacity is left. This problem is mostly caused by leaving your laptop plugged into power always. Therefore, the battery isn’t allowed to die all the way.
Signs of a laptop battery that needs recalibration include; it not charging up to 100%, or getting stuck at 95%. Alternatively, if you notice that your battery charge says it’s got 50 minutes left, only for it to die in the next ten minutes. That is a sign that it needs recalibration.
Here is how to recalibrate a dying laptop battery.
i. You should fully charge your laptop to its maximum limit. Unplug it and allow it to cool to for 2 hours.
ii. Allow your computer to drain the battery completely. Or set it to hibernate when the battery reaches 3%. Provided the battery stays on before it dies out or sleeps.
iii. Leave it switched off for 5 hours.
iv. Switch it on and recharge it to 100%.
You will have recalibrated your old laptop battery life, and this will extend its life. You can also make use of a battery recalibration tool if you are finding it hard to use the manual procedure above. You can find several of these battery recalibration tools online.
4. Swap Cells
We listed this as the final option since it does require some technical skills. But the procedure is quite easy. If you notice your battery dying out in a short period, then chances are the cells might have died. Swapping the cells in your battery with other ones can revive your battery back to its former glory.
Here is how you can go about swapping cells.
i. You need to get your hands on a dead laptop battery, a multi-meter, electric tape, and some wires.
ii. Extract the six cells from the battery carefully to avoid damage. Only cut the series connection. Refrain from the two cells placed in a parallel position.
iii. Confirm the voltage of each cell. It should preferably be above 3.6 volts.
iv. With the aid of the wire, connect these cells in a series connection.
v. In your dead laptop battery, check out the voltage of the primary cells and remove the bad ones.
vii. Insert the battery circuit to your laptop and switch it on. In case it doesn’t work, connect your charger for five minutes and witch it back on.
vi. Afterward, reconnect the cells in the battery pack and keep the circuit. Reconnect the wires as they were initially to avoid short-circuiting it. There are three positive wires, and the longest one is negative. This applies to IBM and Lenovo batteries.
