You don’t have to take complex data analysis tasks out to a remote mountaintop just to enjoy the flexibility offered by a laptop. Working on the go and catching up on tasks while waiting in the airport or relaxing at home in bed can help you grow your business without staying chained to a desk. If your laptop battery is starting to act unusual or won’t seem to hold a charge at all, get to the bottom of the power leak before you invest in a brand new battery.
Five Common Causes Of Dead Batteries
Understanding how a laptop battery breaks down is essential to preventing it. Some of the most common causes include:
- AC Charger Damage – A frayed or broken charger cord can’t refill the battery or keep the laptop on when it is removed.
- Constant Overcharging – Due to the cycling method used on laptop batteries, leaving the device constantly connected to the wall can shorten the lifespan of the battery. Eventually the unit simply won’t hold a charge for more than a few minutes at a time.
- Overheating – Batteries tend to be sensitive to heat. If the power cells are overheating, the laptop may shut off sporadically and fail to hold a charge.
- Driver Problems – Nearly all Windows XP laptops from manufacturers like Dell and Gateway include built-in drivers for battery support. When accidents or viruses destroy the files, the battery can suddenly stop responding at all.
- Age – Laptop batteries just aren’t meant to last forever. The average unit is built for about 2 years of daily use, if proper charging and discharging practices are followed.
The Quick Reset
In many cases, your battery just need to be manually reset to start charging again. It can become physically detached or suffer from software disruption. Both issues have a chance of being resolved with this simple process.
- Turn the computer off. Disconnect the power cord from the laptop and from the wall.
- Close the laptop and flip it over gently. Locate your battery and look for tabs that slide to unlock the power unit. Open any locks and slide the battery out.
- Attach the power cord to the laptop and wall once again. Start the laptop up, then shut it down again through the operating system.
- Slide the battery back in, lock it in place, and start the laptop once more.
You should immediately see the battery indicator reappear and show the charging effect. However, this quick reset isn’t always effective. Move on to the driver troubleshooting steps if your battery isn’t being recognized or if is still fails to load.
Forced Reinstall of Drivers
This sounds like a drastic step, but it is quite simple. Microsoft continues the files needed to reinstall your battery drivers. To trigger this process:
- Open the Device Manager by clicking on the Start Menu and right clicking on the My Computer icon. Hitting Properties and then the Hardware tab will lead you to the Device Manager button at the bottom of the window.
- Click on the Batteries category to expand it. Look for the battery itself, which should be listed as a Microsoft ACPI-Compliant Control Method Battery. Right-click on it to uninstall the drivers. Don’t uninstall the files for any other listings found in the category.
- Follow the prompts to complete the process. Once the battery is no longer listed, right click anywhere on the Device Manager screen and select Scan for Hardware Changes. The computer will recognize the connected battery and reinstall the appropriate Windows XP drivers.
Recovering And Recuperation
The design of modern lithium ion batteries prevents them from being programmed. Other types of rechargeable batteries get stuck at certain charge points due to improper loading in the first days of use. However, this isn’t a problem with most modern computers. It is far more common that the battery’s internal components register the amount of charge incorrectly. This leads to a fully charged unit that reads as empty to the computer. In some cases, a full discharge is enough to reset the sensors and restore proper charging and reading once again.
- Start with a battery that is reading as full charged, or as close as you can come to it. This may only be a few percentage points. Disconnect the charger cord and let the laptop run, with screen saver and hibernate options disabled, until the laptop shuts down.
- Reconnect the charger and let the laptop charge for at least two full hours before turning the laptop back on.
- Check the battery for increased charging capacity.
You also try a battery calibration application. The manufacturer of your laptop may offer one, or you can take your chances with a third party program. Look for a piece of software that can diagnose charging issues and help you adjust them. There is no guarantee it will work with your specific battery, but it is well worth a try before you spend money on a replacement.
Installing the Drivers For A Replacement Battery
When you do make the decision to buy a new battery for your laptop, make sure that the driver files are installed the right way the first time. Find the CD or download link and retrieve your files, then follow these steps.
- Turn off the computer, remove the charger, and take out the old battery.
- Reattach the charger cord and turn the computer on. Insert the disc or navigate to the relevant download location and start the installation process.
- Follow the steps to complete the driver installation. Once the files are in place, shut the computer down once again.
- Add the new battery and insert it into the laptop. Start up the device and give it a chance to boot completely. Give the battery two to three hours to charge fully, then remove the charger to check that it is functioning properly.
Expect to replace your battery at least once every two the three years. While these replacements aren’t cheap, they are still less expensive than a brand new laptop.
