Hi there
When you plug the AC adaptor in, does the battery charging light come on? Will the laptop boot from the battery? If the answer to both of those is yes, it would seem like a Power for Gear problem. You might want to try removing and reinstalling it.
If, however, the battery light isn't on and the laptop won't boot from the battery alone, you may want to remove the AC adaptor and then remove and reseat your battery. While you have the battery out, if you want to be thorough about it, you can clean the battery's contacts with some rubbing alcohol and a swab stick to make sure you're getting a good connection between the battery and the laptop. Reinsert the battery and see if Power for Gear detects it then. You might also want to check the Power settings in the Control Panel to see if the battery is being detected by Windows.
You can also try running the Mobile Meter to see if it detects your battery.You can find that information by running the MobMeter and right clicking on its window and choosing Options, then click the Battery Information tab
This kind of battery rarely occur the quality problem, If convenient,it's good idea to put the new battery into another laptop(using window XP/2000) to check if the battery is fine.
If you are unable to start the machine normally with the battery, please check whether the battery is put well, try to update the BOIS version or change the power options
Please disconnect the AC adapter and use your laptop until it itself shuts down, and using original adapter to charge the battery for 24 hours( Ignore LED status)
The service life of the battery is limited. When it is used for a certain period of time, the capacity will drop rapidly. You can consider to buy a large capacity battery for your notebook, and use it in good way in order to prolong its service life.
Hope can help you.
Best Regards,
Fiona
