Laptop Battery Repair At Home

Do you frequently ask yourself, “How can I perform laptop battery repair at home, and then will it charge?”

Laptop batteries are critical to laptop performance. If your laptop battery isn’t charging properly, there are a few problems and options to consider before purchasing a replacement.

One of the most common issues with laptop batteries is that they don’t charge or lose charge quickly after being completely charged. The main cause of this issue is because the battery has reached the end of its functional life.

Batteries have a set number of charge/discharge cycles before they become unusable, which can range from 300 to 500 full cycles depending on the manufacturer’s specs. Alternatively, you can replace or recharge your current battery.

Follow these simple steps if you want to take advantage of your laptop’s portability without depleting your wallet:

The battery pack should be removed

Remove the battery pack and leave your laptop for at least an hour to ensure the motherboard is completely powered down. For roughly 4 seconds, press and hold the ‘Power’ button, then release it. Any remaining electrical charge in the computer’s memory will be discharged.

 Ensure that the battery contacts are clean

Locate the laptop’s battery jack (located on the underside of the unit). Disassemble the laptop carefully until you reach the main circuit board, where you may access the jack. To avoid scratching the motherboard, use a little Phillips head screwdriver or something similar.

Unplug and set away any screws leading up to this point, then carefully peel off the lid to avoid damaging any interior wiring or components.

Clean the surface of both ends of your battery’s contact points with an alcohol-soaked cotton swab. The battery contacts are on a small rectangular chip, which is normally a grey block with two contacts facing down and one looking up.

Make sure any other metal chips you find are clean as well. Wipe all of the chips with a soft cloth until all of the residue is gone.

Make sure there’s no rust

Furthermore, corrosion under the circular contact stickers on batteries without replaceable storage components often causes what looks to be a defective battery (that is, those without memory).

Corrosion causes these circular stickers to ‘disconnect’ from the battery, reducing the battery’s charging capabilities. In this situation, use a small flat-head screwdriver to gently scrape away any rust on either side of the stickers, going from the centre out to the edges.

Whether or not you need to replace your battery entirely depends on how much corrosion is present under these circular contact points. If it’s really bad, consider buying a new laptop because most laptop batteries can’t be removed and cleaned other than by removing the notebook itself.

There is no way to remedy an internal issue like corroded metal contacts without being able to remove them from the system.

If you don’t want to do it yourself, choose a trustworthy laptop cleaning service to do it for you.

Not Powering up

You can investigate what is causing your laptop’s lack of power now that the battery has been removed. If your cables or terminals show symptoms of corrosion or rust, remove them and polish them with sandpaper after disconnecting them.

After that, detach them again and liberally coat them in dielectric oil before reconnecting them. This should aid in the prevention of future build-up.

Next, look for any obvious damage to your charging cord or wall outlet, as these are also common difficulties if they have recently been jolted. You can clean them with a rubbing alcohol-soaked cloth, but this should only be done as a last resort if you don’t have any new components on hand.

If your laptop still won’t charge after completing these simple steps, the circuit board within it could be damaged. Unless your laptop is under warranty, it is usually worth investing for a laptop repair.

How do you get the battery out of your laptop?

Perform a google search on your laptop model number and the following keywords: “remove the battery” and/or anything similar to see how tough it will be to remove your current battery.

Once you’ve determined that you can remove the battery, begin by completely opening the laptop to examine where the battery is placed. You should be able to see either this pair of screws or some form of lock holding it in place.

If you’re using any metal implements, be careful when removing these screws because computers often have elements that are connected even if they don’t appear to be.

Depending on whether or not there is a latch keeping the battery in place inside, the battery should come right off. If there is one, make sure it is entirely released before you remove the battery.

If you don’t, the latch may prevent the battery from fully removing, making it difficult to work with afterwards.

In the vast majority of cases, simply replacing your battery will resolve the issue. To do so, switch off your laptop and unplug all of its devices. Remove the battery and disconnect the AC adapter.

To figure out how to open your laptop’s case properly, look for the handbook (if you can’t locate it, search online for “manual” followed by the brand and model of your laptop).

Locate the existing battery once inside. A bar or label should indicate which end is positive and which end is negative (most batteries have “+” indications; some have softly coloured bumps at one end).

Make careful you don’t touch them until the power has been turned off! Disconnect any wires connected to this now-ineffective component, including any tape holding it un place, and carefully slide it out of its bay.

How to Replace a Battery

It is necessary to replace the laptop battery with a new one that meets the same specs. The new battery’s capacity must match or surpass the original battery’s capacity, and its voltage rating must match or exceed the original battery’s voltage rating.

You must also make sure that your laptop is compatible with this sort of battery; otherwise, the laptop may not work correctly with it installed.

Batteries that are compatible

A replacement battery must be compatible with your laptop before you purchase it. Voltage rating, capacity (mAh), dimension (length, width, depth), aspect ratio (laptop width versus height), and connector type are all factors that differentiate batteries for different laptop models.

Because each model differs, not all batteries will fit each laptop, even if they appear to be identical or fit in the same place as your original battery. This is especially true for refurbished/refurbished batteries, which tend to differ slightly.

Aside from assuring compatibility, it’s also critical to utilise the correct sort of battery while replacing it. Batteries, in general, but not always, are finicky about whether or not they can be used as replacements.

If your battery is built-in and cannot be removed (for example, an internal laptop battery), it must be replaced with one that is identical to the specs—there is no other option.
