The problem may be with the computer BIOS and an update is required for the laptop to recognize and fully charge the laptop battery. The current software in your laptop is only set up to read an OEM (Original Equipment Manufacturer) battery. If your BIOS has not been updated, and you have only used Original batteries in your laptop, it can cause the replacement battery not to communicate correctly with the software in your system.
Check your manufacturer’s website for possible system BIOS upgrades for your laptop model. Some laptops have been prone to reject third party batteries if they have an old BIOS version installed. Once completing the BIOS upgrade, please recharge your battery for 12 hours and use as normal.
New batteries come in a discharged condition and must be fully charged before use. It is recommended that you fully charge and discharge the new battery four to five times to allow it to reach its maximum rated capacity.
It is generally recommend an overnight charge (approximately twelve hours). It is normal for a battery to become warm to the touch during charging and discharging.
You might need to recalibrate your laptop for the new battery. You can easily recalibrate your laptop properly via the Windows Power Management.
With Windows XP, you can change the battery settings by navigating to Control Panel > Performance and Maintenance > Power Options. Once you find it change the “Power Schemes” to “Always On”. Under “Alarms”, uncheck “Low battery alarm” and “Critical battery alarm”. Under “Hibernate”, uncheck “Enable hibernation”, and then click on Apply.
This is the only time that we recommend taking the battery all the way down to zero %. You should also unplug the ac adapter and let the battery drain all the way down until your laptop shuts off. After that, plug the ac adapter back and charge it to 100%. You may need to repeat this process about 2-3 times before it actually reaches 100%.
This is known as "False Peak" and is very common condition during first time battery use (or using a battery that has been discharged for several months). The charger light may go out after only 10-15 minutes, indicating that it is fully charged when it is not. Should this happen, simply leave the battery on the charger for about an hour. Remove the charger, and plug-in the charger immediately. The battery will resume normal charging and the charger light will indicate when the battery is ready for use. This may happen several times during the first battery charge. Don't worry; it's perfectly normal.
Some Sony laptops have a pre-installed utility called Sony ISB, which prevents the laptop from using a third-party laptop battery. To remove the Sony ISB utility, follow the directions below:
1- Turn off the computer and remove the battery.
3- Click the Start button, click All Programs , click Accessories , and then click Run .
4- In the Run window, type MSCONFIG and then press the Enter key.
NOTE: If prompted for an administrator password or a User Account Control prompt is displayed, type the appropriate password, click Continue or click Yes .
5- In the System Configuration window, click the Startup tab.
6- On the Startup tab, click to uncheck the box in front of ISB Utility
7- Click the OK button.
8- In the System Configuration window, Click the Restart button
9- Tutn off the computer, reconnect the battery and turn the computer back on.
This will remove the software check that Sony has placed on its laptops to prevent third-party laptop batteries from being used and allow you to use a non-Sony laptop battery. Some Sony laptops have a hardware laptop battery lock which will prevent a third-party laptop battery from being used. In that case, there is no "fix" to get around the hardware lock and you will have to buy a genuine Sony brand laptop battery only.
If you are getting the “Plugged in, not charging” status on your laptop battery, please following the steps below:
Status should now say, “Plugged in and charging”
