Top 10 reasons a Laptop Battery Will Not Charge

1. Worn-out or Defective laptop charger
Laptop power adapters can wear-out from general wear and tear to more specific problems, such as major kinks in the cord.

2. Under-powered Laptop Charger
In some cases a laptop charger cannot supply enough power to charge the battery while running the laptop. This is common with extended run and universal laptop batteries and chargers. Be sure the power ratings on your laptop, battery and power cord all match up.

3. Defective or worn-out power socket on laptop chassis
This is a common problem that leads to a laptop not charging properly. If your laptop and/or charging cord must be positioned "just-right" chances are you need to replace the laptop power socket. This can be an easy fix with a little bit of research and the right tools.

4. Laptop was not properly restarted when new battery was installed
Some laptops need to be powered down to recognize a new battery. Closing the laptop screen or using the on/off switch may only put your laptop into sleep mode. Be sure to properly restart or power-down your laptop after installing the new battery.

5. Battery was used to zero percent
If a battery was discharged all the way to empty it may not have enough energy to power on. This battery is likely beyond repair and will need to be replaced.

6. Battery was not charged 100% before first use
When batteries are new, they are not at 100% capacity yet. They need a little bit of exercise for them to hold their full charge. Charge the battery overnight and use until 20%, then recharge the battery again. Repeat this process five times to fully condition your new battery.

7. Laptop was recently upgraded to a new version of Windows
Changing the operating system on your laptop (especially Windows 7) may result in mixed communication between the laptop and the battery.

8. Battery management software is incorrectly calibrated.
Sometimes the battery may be charged but the power gauge is not reading accurately. This is common on extended run batteries. You may need to calibrate your laptop battery. Go to our “calibrate a laptop battery” page.

9. Battery is defective
All Xtend brand laptop batteries and power cords from Laptop Battery Express carry a two-year warranty and 30-day money-back guarantee. OEM batteries and chargers carry a 1 year warranty.

10. Recharging circuit on motherboard is defective.
This is not a likely problem, but it can still happen. This requires the replacement of the motherboard. This repair can cost up to $500.
