Eventually your battery will have a short/no life indeed. Though this happens to all laptops. Using your laptop while it is charging isn't going to damage anything. It just means that the battery will take longer to charge because you're using the laptop. To get the most life out of the battery, fully charge it and then use it until it is empty. It's also a good idea to remove the battery when the laptop is connected to the mains supply. All you're trying to do is extend the life of the battery. The day will come when it holds a short/no charge.
There are five common laptop battery knowledge you should knowQ1: What does 3 cell, 6 cell means we said normally? Is it related to the battery capacity? A1: 3 cell, 6 cell means the battery cell amount in the battery. The more batteries cells, the greater capacity of the battery, and also the longer use time.
Q2: How many kinds of the laptop batteries? A2: It is mainly divided to nickel-cadmium battery, Ni-H battery, Li-ion battery. They always show as Ni-Cd, Ni-MH, Li. Recent years, a kind of fuel battery appears in laptop field. The present laptop commonly use Li-ion battery, but seldom model still use the obsolete Ni-MH battery, consumers can identify this from the sign on the batteries.
Q3: Why the manufacturers only implement 1 year guarantee policy for the battery? A3: Li-ion battery working life is very short. Normal Li-ion can only charge 400-600 times. After special improvement battery also can’t exceed more than 800 times, it turns to obsolete after 2 years working life. Q4: Why do the batteries can’t be use reach to the nominal time which announced by the manufacturers? A4: The test condition is different. Some manufacturers use 8 cell battery to do test, but supply battery users 6 cell battery, some manufacturers close all the programs, turn down the LCD screen brightness, ban to using high power interface and other measures to test the working life, but it is can’t be reach in the daily life. And some other manufacturers only use the software to do test, but software test may cause error.
Q5: What should be take notice for the using and storing of the battery? A5: Users should pay attention to below points: 1 The battery should be charge full over 8 hours in the beginning charging process to activate the Li-ion battery sufficiently. 2 The battery can not be discharge excessively. 3 It is better not to use the battery when use the AC adapter at the same time. 4 Storing attentive points: The battery should be take out to charge at least once monthly, It is inadvisable to store the battery when the battery is full, it is good to charge only 40% - 50% for the storing purpose, last but not least, the battery should be put in the dry and shade places. more batteries info via : http://www.sales-battery.com http://www.global-battery.co.uk
Typically these automatic battery replacement messages are generated by a few different things.
1. number of charge cycles the battery has been through, typcial recharge rating for LIon batteries in laptops is 500 cycles.
2. The charger circuit in the laptop has detected that it cannot charge the battery as much as before.
3. Based on rundown time that the laptop experiences, ie how long a battery is lasting compared to new.
On my Lenovo X series, I started noticing that battery life was down from 6 hours to about 2.5 or less and then I got a message from the power monitor software that informed that my battery was only capable of holding 32% of new charge. As I rely heavliy on my laptop in situations that have no battery power I elected to replace the battery. If you do not use the battery much, then you can likely chose to ignore this message.
That means that female connector where you connect the end of the charger to the laptop is has a cracked solder joint. This will require opening the laptop and soldering it again. A very tedious and delicate job. The reason why it will only charge when it is off is because of poor connection, but when you turn on the computer, it requires more "juice" and the poor connection cant handle it anymore so it quits charging. If you decide to open your laptop be very careful and pay attention to details. Never force anything. Good Luck.
Most laptops will work without a battery as the house current is converted to usable voltage for the lap top as well as to charge the battery.
The battery is not charging because the voltage level has fallen below a safe level to recharge. Li-ion batteries have a safety feature built into them. A small chip is wired into the battery to tell the power supplly on the lap top that it is OK to charge the battery. If Li-ion batteries internal charge fall below a certain level, that chip signals the charger not to try to charge the battery as it would demand a higher charge rate and raise the battery temperature and cause a fire, so it in effect says don't do it. If the battery charge falls further, then that chip locks out the battery and shuts down your computer.
One thing you can try, put the battery in your freezer for about an hour, and then put it back in your machine and see if it will come back to life. Do not let the battery freeze, just an hour will do. You may want to try this a couple of times, but your batter is at it's life end.
2 hours is enough for a battery to be completely charged...
Once the battery is charged you can remove the power supply and use the laptop till the battery drains up to 10% to 14%......
This will increase the life time of battery... If you keep on charging the battery continuously when using your laptop, then the battery life will be shortened very soon...
So charge and drain the battery properly... This will increase the life time of battery...
Let the thing drain completely down to nothing. When the pop up window says you gotta plug the thing in, just ignore it and do your thing. When the computer shuts off by itself, hold down the power button for 5-10 more secs to fully drain the thing. Then plug your computer in and let the battery charge for a good 6-8 hours. Then unplug the charger and let the battery sit and cool down for about 15 minutes. This is called conditioning the battery and should be done once every other charge. Also, its a good idea to turn off your wi-fi if your not using it, bring the brightness down on your screen, and close any non-essential applications that are running. Cheers old chap.

Or it could be a broken/damaged power pin that is causing the problem. Every time you tug or pull on the pin it causes damage...eventually it doesn't work at all. When you get it fixed you need to invest in a CRD (Cable Retention Device) like shown here. . .
