A reconditioning process for laptops - what to do when your laptop battery dies
It can be very irritating when your laptop battery actually fails, because this makes the laptop very difficult to use. For example, if the power goes down, so too does your laptop, and you lose data and perhaps even corrupt your operating system, and we all know how very irritating that is.
You really have very little option other than to go out and buy a new battery, and we all know how expensive those are. You don’t have a choice, though – or so you thought.
Actually, the simple fact is that a laptop battery can be reconditioned and brought back to active service, so there’s no need to throw it away and spend a lot of money on a new one.
Reconditioning a laptop battery is actually quite easy. All you have to do is follow the procedure I’m going to outline here.
The first step is to remove the battery from your device, obviously. Next, you will take a sealing plastic bag and place the battery in it. It is advisable to place two or three sealing bags, one inside the other, with the battery in the innermost, and all of the bags sealed.
After doing this, you can put the package in your freezer. The sealing bags are to keep moisture out, because this can be deadly to the battery, but if the battery is inside three sealing bags, you should have no problems.
Leave it inside the freezer for roughly twelve hours or so.
Then take the battery out of the freezer, let it return to room temperature, and insert it into your device. Put the device on the charger, and charge the battery. This method usually works to recondition the battery, and the battery should run for a considerable period of time after this point.
Calibrating your laptop
Generally speaking, to achieve the best effect, you also need to conduct a process called ‘calibrating’ your laptop, along with the procedure I described earlier. This is because many devices’ operating systems tend to get out of sync with the battery and show false readings when you use the device to try to find out how much power you have left on your battery. This applies to onboard applications as well.
To recalibrate your laptop, charge the device until the battery shows a hundred-percent charge, and then switch off the mains power and allow the laptop to run off the battery until the battery is entirely drained and the device shuts down.
You must leave it in this completely discharged condition for up to six hours. After around six hours or so, you need to switch on the mains and recharge the battery until it is once again at full charge.
This procedure recalibrates all the systems in your laptop, and allows you to get a precise and correct reading on your battery.
Please note that how efficiently these procedures work also depends on the kind of battery your laptop uses. There are specific reconditioning processes that work for nickel-cadmium or nickel-metal hydride batteries, which may not work for a lithium-ion battery. So, check what battery your laptop is actually using before trying any reconditioning process.
