Tip & How-To about Computers & Internet

Battery problem's it just need a reset, yes batteries have a "Brain" too.

So, lately your laptop battery has been giving you a less than stellar performance. As a matter of fact, the battery life has been downright poor. You give it hours to charge, and you barely get ninety minutes of battery life from it. If your battery is less than two years old, then you may be able to do something about it. Something, that is, besides going to the electronics store and shelling out your hard earned cash to buy a brand new battery. That choice is to try and reset your battery. It may not be a silver bullet, but it can help you to extend your battery's active life. There are two ways to reset your battery. Like many other things in this world there is an easy way to do this and a hard way to do this. We will begin with the easy way, which does not require a download, and then move on to the hard way.
The Easy Way Before we begin look at your battery and the casing directly surrounding it. If you see an inset button labeled “Reset” (like the ASUS A6403KM), and you are sure it is for the battery only, then you can use the method with a reset. If not, then use the directions without a reset.
Without The Reset
If your laptop battery does not have a reset button, then follow these steps:
1. Turn off all of your power saver settings on your laptop. This includes your sleep mode and any auto shut offs.
2. Use your laptop, do whatever you have to do, and run the battery down. Ignore any low battery messages.
3. Your laptop is going to die, so be sure that if you are doing anything mission critical save your work.
4. Plug it in and let it get a full charge without turning it on. Not even once. Not even to check your email really quickly.
With The Reset
If you have a reset button then try these steps:
1. Interrupt the battery recharge from step four above after about 1 hour.
2. Hold your power and reset button simultaneously for about a minute, your lights should flash.
3. Turn off the device as normal and finish the charge.
The Hard Way The hard way is to get and run a piece of power manager software that will manage your battery reset.This is intended for those who repair and restore laptop batteries, or at least folks that can open their laptop battery's housing and identify and remove the "smart chip" inside.

Please be aware that this software is designed to be run by a technician. If you are not one, then be very careful to follow the directions carefully.

Very poor battery life, have to keep it plugged into mains almost all the time. This is after less than 3 years old, probably nearer 2.

Hello there,

Yes my dear friend, the battery is bad already that is why it seems like you have to get it plugged into the mains all the time when you are using the laptop.

The battery tends to last for over three years, but there are some things that gets to drain the life cycle of the battery.

Things like, plugging the laptop when ever it is in use. Once the battery is full, one needs to get it unplug it from the mains and use the battery till it is low before connecting the charger back on it. That way, the battery will last a while before the cells die off. As constant charge gets to weaken the battery cells and therefore makes the battery weak and unable to hold a charge.

The battery can also get bad if the voltage used to charge it is very high. High voltage tends to kill the battery cells also.

Some times, the battery could last for over three years and at times less that. The cells in the battery could get weak at any time. So I will advice you get another battery and this time, take caution on how you get to charge the battery.

Hope this was helpful to you.

Milwaukee Tools18V Lithium Ion battery is very intermittent in performance, it performs very poorly in the garage at 35 degrees, short battery life, poor performance, sometimes the battery will charge and run well, other times when the indicator shows at least 50% the battery will last only seconds, batteries are less than two years old, very puzzling

Depending on how much you have used them, two years may be all you are going to get. Make sure the battery is fully discharged before re-charging if you have not tried that already. It is recommended for those type. Sound like just need a replacement. Are you sure the charger is ok? take care.

Battery life

Batterys in laptops are now Lithium Ion batterys (li-ion) these batteries do not have a memory effect so it does not matter if you leave the laptop plugged in or not, you will not affect the performance

Compaq F700 Battery live very less

Its normal, generally it comes with 80-90 min. You can use HP Power management to optimize the use of battery. Making screen less bright will increase the power backup.
