My computer keeps going off

I've had my laptop for about 2 years now and the battery life has slowly been declining. it got to the point where the low indicator has not been coming on and the laptop just goes off. when this happens, upon restart there is usually entries for norton that are corupt and get deleted when i do a dskchk.
i have bought 2 genuine batteries and tried these but can only get about 30 mins out if each of them. with one of these batteries the same problem occured. with 70% power the computer just went off, no shutdown.
do you know if is it a hardware or software problem?
any solutions would be helpful

Tip

The Most Important Considerations of Using Laptop Battery


1, when no external power supply situation, if the working conditions at the time slot being less than PCMCIA cards, it is recommended to remove the card first to extend battery life.
2, room temperature (20-30 degrees) for optimum battery working temperature, the temperature is too high or too low, the operating environment will reduce battery time.
3, can provide stable power supply environment, using a laptop computer, remove the battery for extended battery life is not right by. On Asus notebooks, when fully charged battery, the battery charging circuit will automatically shut down, so the phenomenon of overcharging does not occur.
4, the recommended average of three months to conduct a battery power correction action.
5, to minimize the number of NIKON en-el3e battery
The battery charge and discharge is directly related to life, one charge, the battery a step forward to retirement. Suggest that you use an external power supply,
6, the use of an external power supply when the battery removed.
Some users often plug the power several times a day, and the laptop is equipped with batteries, do more damage to the battery. Because each access to the equivalent of an external power supply to charge the battery once the battery life shortened by a natural.
7, after the exhaustion of battery charge and avoid the long charging time
Regardless of your notebook to use nickel-metal hydride or lithium electricity, to power after the exhaustion of a certain charge (charge less than 1%), which is the best way to avoid the memory effect. Lithium also have memory effect, but its memory effect smaller than nickel-metal hydride Bale.
8, the usual precautions
When used in peacetime to prevent exposure to prevent damp to prevent the erosion of chemical liquids, avoid contact with the metal battery contacts, etc. happen.
When you purchase your laptop battery
Laptop battery life - as no more than 3 to 4 years, it may be users of the most likely to replace things. Two years after the laptop, you will find the battery consumption and faster. If possible, you can replace the old batteries for new batteries to ensure the stable operation of the computer.
When the need to replace the notebook computer batteries, best to choose the same type of battery replacement. However, if the old computer using a nickel-metal hydride batteries, to make a longer battery life, of course, can also be specified by the computer user manual or manufacturers recommended models use lithium batteries. Although the nickel-metal hydride batteries for cheap, but there is memory effect, and in the same capacity than the lithium batteries under the weight of large, and lithium batteries have no memory effect, light weight, power supply for a long time, etc., has become a standard notebook computer batteries . Lithium batteries used in notebook computers at this stage because the different manufacturers in the power of time there are some gaps, and friends in the purchase process should be noted that different brands of the difference in the Sony vgp-bsp13/s Battery, the best among several brands compare.
Performance battery power supply in addition to the stated time manufacturers, but also need to pay attention to their capacity. Battery capacity is usually AH (ampere-hour, ampere-hour) calculated with the current laptop is 4000AH most about, and a battery can last for 2 hours or more. In addition to the battery power supply time by the whole power of computers and the impact of factors such as heat dissipation, the screen size (bigger and more power), screen brightness, and the implementation of the work and so will affect the power of time.
Now the price of laptop battery up and down the ocean in 1000, accounting to 10% of overall price notebook - about some of the ultra-thin models or even higher. The battery warranty period, is guaranteed 3 months, and is guaranteed six months, the longest, but also for 1 year; the reason why the warranty time is short battery laptop battery is easy because of consumables, the number of charge is constant, with a little time. Moreover, the laptop battery and other hardware different, there is no room for repairs, can only be a new one. The products of such a long warranty (replacement), intangibles to increase the burden on manufacturers, so buy laptop, be sure ask the battery warranty period and conditions.
Also in the purchase of second-hand laptop computers, they also do not forget to try it inside the battery can continue to work long. Under normal circumstances, the use of one or two years after the laptop is fully charged, the nickel-metal hydride battery can support about 1 hour or so computers at work, lithium-ion battery can support nearly 3 hours, but relative to the terms of this new battery requirements are already very low, and able to meet this target from the scrap to the battery of far away.
Causes of Damage Laptop Battery
Notebook computer CANON nb-6l battery a long time, often charge less for electricity, and even shows the battery is damaged, the specific performance of a larger resistance, the voltage across the charging up faster. So easy to charge control circuit is judged to have been filled, the capacity will naturally decline. Since the battery internal resistance is relatively large, the discharge voltage drop when a large, fast, so the system is easy to mistakenly believe that the voltage is not enough, lack of electricity. Comparison of the discovery of short battery life, should take appropriate measures.

How to increase your Laptop Battery's Life?...


I have a interesting tip to increase your Laptop's battery life. There is no matter, laptop manufactures gives you the guarantee about the battery that how long it works. The battery of laptop always stops working very early at some stage in essential research, just like when you are watching a DVD movie.


Follow the few steps to increase the laptop battery's life :


1. Lower the backlighting on your screen.

The screen of your Laptop takes up significant amount of power and you do not require its maximum brightness. You should have to check your system and decrease the screen brightness it to a comfortable point.


2. Stop your wireless signal when you are not using.

After turning off your Laptop can save max. 20 minutes of your laptop's battery time because WiFi can use a considerable quantity of power. By right clicking you can stop your WiFi signal when you are not using.


3. Manage the correct power scheme in XP
Windows XP contain a number of predetermined power plans, which control settings like how rapidly your laptop turns off and when your screen saver boots in. You can change your laptop power scheme by choosing Control Panel > Power Options. For max. Battery life from the "Power scheme" chooses the option "Max. Battery" and decline the list. There are good choices for you just like "Low Power Mode" and Portable /Laptop. They don't conserve as much power as Max Battery. After selecting a power scheme you click Ok button to finish the process.

3.try to charge your battery constanly,and unplug it when you think its almost fully charged,overcharged can heat your battery and damage it
4.keep your laptop as cool as possible,don't try to charge the battery when the computer is turned on,even if the battery is going to 0 and you still need to use it,just shut down the laptop first and charge it,at least until the battery is charged 20%,unplug the charger and turn it on

You need a new battery. One or more cells is defective. Obviously it's unsafe to continue using a battery pack if it gets hot enough to cause burns, so remove the pack from the computer. You can continue to use the computer on AC power until you get a replacement battery.

You might try contacting HP to see if there's any kind of warranty accommodation they can make. I've found several mentions in various forums about batteries in similar models going bad and that HP replaced them, but they were all within a year of purchase. Can't hurt to ask, though.

The battery starts a slow decline over months and years, eventually you will notice the time between charges gets less and less until you are down to minutes, this quite normal for these batteries. The average life span is one to three years for most batteries before replacement is required.

Hi,
Laptop battery notification is not accurate but approximate. The remaining battery usage is calculated approximately and then notified to the user. If your battery's life is more than a year, then the calculation goes on decreasing. It cannot be rectified unless you go for a new battery. But still you can tweak the battery life by,
1. Switch of the wireless adaptor when not in use.
2. Decrease the screen brightness.
3. Configure your power plan in control panel to minimal power usage mode while on battery.
4. The notification limit for battery low can be custom configured in the control panel. set it to 30 % and this will prevent your laptop to dye without power as your battery power drains faster below 31%
I hope this is helpful to understand the logic behind this.

Bad battery or bad motherboard?


If the first batteries died slowly over time then yes this would suggest a depleted battery. If then the secondary batteries you bought were holding charge but didn't keep them for very long, and didn't hold a charge any more, this could be due to one of two things. 

1- the supplier you bought the batteries from shortchanged you with unofficial products

2- the it dept is right and the recharge circuit on the batteries has gone, in all the laptops. Instead of buying a load of new laptops perhaps a new device to charge the batteries is in order. Battery charging stations for laptops are available. Ask your IT dept.
