There are three potential causes for your battery not to charge:
1. Your power supply may no longer provide enough power to charge the battery and power the laptop.
If possible try another power supply.

2. The battery may have failed and needs to be replaced
Most laptop batteries are designed to "self destruct" if they detect a fault with one of the battery cells internally and will lead to a "no charge" situation. This activity is intended to prevent a fire, the battery should be replaced and recycled.

3. The charging circuit in the laptop may have failed. This would require a new motherboard to repair.

Fully charging a bad battery is a waste of time as the bad cell discharges internally. Best have a load test done on the battery to eliminate it first.

How to charge your laptop battery properly? During the the process of notebook...


How to charge your laptop battery properly? solarroll-laptop-solar-charger.jpg During the the process of notebook using, we need no to deliberately charge the laptop battery to 100% state or fully discharged laptop battery to automatic shutdown protecting. The correct way is that charge the battery in 20% state and stop charging in 98% . If the machine has the power calibration procedure, when the battery standard-by time significantly reduced. Then calibrate the battery in time to active the protection circuit performance.
For early notebook batteries (Ni-MH Ni-MH or Ni-Cd Ni-Cd), really need to fully charge and discharge in order to maintain good battery capacity. But for the lithium battery is not necessary even it may damage the battery.
In fact the lithium batteries has a little memory effect. The lithium battery materials is very sensitive to the conditions as temperature, the use of frequency and so on. The battery will be aging after used for some period time (standby time reduced). The natural wear and tear is an important reason, and inadequate maintenance is another important reason.
A well-designed lithium batteries have a very good protection circuit to prevent excessive charge and discharge.As over-charging and discharging of the Sony VGP-BPS8 battery will be the rapid reduction activity. Under the protection of protection circuit, the user fully charge and discharge the battery several times, in fact, impossible to achieve had "full" level.
Sometimes WINDOWS show that battery capacity is 20% or more, you can use 30 minutes. But after used 10 minutes or less the machine suddenly automatically shut down. The reason is that the battery has been aging, the battery protection circuit can not monitors the battery real capacity. In the normal battery depletion, the protection circuit original parameters have been unable to properly reflect the actual situation of the battery
So power calibration procedure is to correct the benchmark protection circuit parameters to accurately reflect the actual capacity . This correction process will often take two or three complete charge and discharge. As previously mentioned, fully charge and discharge will reduce the battery activity. It is not frequently used, usually once a month.

I have a Dell XPS M1210 laptop for which I have just purchased a new 9-cell compatible battery. It worked great for a couple of hours, but now shuts off immediately when unplugged from the AC power supply....


You might want to try what I did when I had a completely discharged battery for my Dell Laptop. I attached the battery to the computer, make sure the computer is off and plug in the charger for a full twenty four hours (undisturbed). And this really worked. I had no problems with the battery. Good luck.

Battery fully charged but still shutting down when disconnected from mains


Find another battery it says like the one you have is faulty. If you try another known good battery and that fails just like yours then try a know good ac adaptor. If that fails, then its a problem with the motherboard not charging batteries properly but it really does sound like a faulty battery from my experience.

Laptop power connection faulty


Hallow Dear,

As your explanation about Battery issue simply I’m advising you to replace your battery with original one.

But before that there is one thing that you can try it out.

---Use your laptop until battery goes down & shutdown automatically then remove the battery and try to discharge it completely with small bulb manually

When it’s on completely discharge (0 Volt) keep it on Outdoor Sunlight about 12 hours.

After that connect it to your laptop & recharge it completely (until Computer LEDs showing you as Fully Charged)

****** REMEMBER DO NOT TURN ON YOUR LAPTOP******
Until its Showing you as fully charged

That will be nice if you can check Battery Voltage & Amperage manually as it is charged fully before turn on your laptop. (if not you can give more charging time accordingly)

This will not solve your any component (thermal fuse, vRegulate) problems inside your battery but will increase your battery Cells Life and most vStoraging problems on Cells inside your battery

Thank you & Best Regards
Dinu….
