Yes Its okay, if your laptop shutdown by itself when you use the battery, it may be because the battery is not charge enough or it may not be working properly

My acer wont start up


Acer laptops allow you to take your work and entertainment on the go.

You can work on a presentation during a long flight or watch a DVD in the middle of a park.


Acer laptops can do this because they are powered by batteries, allowing the laptop to run without having to be plugged into a power source.


Normally, the battery can be recharged by plugging the laptop back into a power socket.


But certain problems can keep the battery from charging.

Electrical Connection


For laptops to charge, they need to be connected to a power source.


Although it may look like you have the cable plugged in correctly on the Acer, make sure that the cord is firmly plugged into the power socket.


There should be a light on the Acer keyboard as well as a power symbol on the taskbar for your operating system that tells you whether the laptop is running off electrical or battery power.


If it is plugged in, make sure that this icon shows that it is on electrical power.


Also check the socket where the Acer is plugged in and make sure that it isn't turned off at the main circuit breaker.


Battery


Turn the Acer over and make sure that the battery is properly placed in the battery compartment. Most laptops will have locks that keep the battery securely in place.

These locks can sometimes come loose.

Use a piece of strong tape as a temporary measure to keep a loose battery in place.


Clean the terminals on the battery to ensure that there is a good connection.

Remove the battery from the battery compartment.

Apply rubbing alcohol to a lint-free cloth. Rub this cloth over the shiny metal terminals on the battery.

Over time, batteries lose their ability to be recharged.

If neither of the aforementioned steps works, you may just have a bad battery.


Check with Acer or other vendors to find a replacement for your model.


BIOS Update


The BIOS (Basic Input Output System) controls a number of basic functions for a computer, such as assigning the hard drives and other system functions.



The BIOS also controls the battery charging function.

Certain Acer models have a bad BIOS that operates the computer normally but doesn't charge the battery.


To solve this problem, you need to perform an operation called Flashing the BIOS where you download a new version of the BIOS and upload it to your Acer.


Check on the Acer support site to see whether your computer model could possibly be affected by this.


Adapter


The power adapter, the part that plugs into the Acer from the power socket, can go bad.


Check for a power light on the adapter.


If the light is not lit, you probably have a bad adapter.


Replacement adapters can be purchased from Acer or other online vendors.

The initial battery of my Acer Travelmate 2480 packed up and I ordered and installed a new one. However, the laptop remains on "AC Only" power and the battery is not charged, giving a...


RTFM You can download the manual by googling "acer travelmate 2480 manual" (without the quotes). Or just click here

According to the Acer manual:

"Conditioning a new battery pack
Before you use a battery pack for the first time, there is a
"conditioning" process that you should follow:
1 Insert the new battery without turning the computer on.
2 Connect the AC adapter and fully charge the battery.
3 Disconnect the AC adapter.
4 Turn on the computer and operate using battery power.
5 Fully deplete the battery until the battery-low warning appears.
6 Reconnect the AC adapter and fully charge the battery again.

Follow these steps again until the battery has been charged and
discharged three times.
Use this conditioning process for all new batteries, or if a battery hasn't
been used for a long time. If the computer is to be stored for more
than two weeks, you are advised to remove the battery pack from the
unit.

Warning: Do not expose battery packs to temperatures below 0°C
(32°F) or above 60°C (140°F). Extreme temperatures may adversely
affect the battery pack.

By following the battery conditioning process you condition your
battery to accept the maximum possible charge. Failure to follow this
procedure will prevent you from obtaining the maximum battery
charge, and will also shorten the effective lifespan of the battery.
In addition, the useful lifespan of the battery is adversely affected by
the following usage patterns:
• Using the computer on constant AC power with the battery
inserted. If you want to use constant AC power, you are advised to
remove the battery pack after it is fully charged.
• Not discharging and recharging the battery to its extremes, as
described above.
• Frequent use; the more you use the battery, the faster it will reach
the end of its effective life. A standard computer battery has a life
span of about 500 charges."

Laptop Won't Boot


You'll need to troubleshoot your laptop in order to know what the exact problem is. First try to plug it in with the battery on and try turning the laptop on. Next would be to remove the battery and plug the computer. If this doesn't work then it's definitely the AC Adapter and you'll probably need to call toshiba to purchase a new one from them or if you're still under warranty then have it replaced. They also have some qualifiers on whether an AC adapter or battery is qualified for replacement even if it's under warranty. Just call them on 1-800-457-7777 and ask their technical support reps about this.

My laptop battery won't charge


possible when the old AC adapter blew it took part of the power management circuit with it, This is the circuit that detects and charges the battery, I'm not sure whether this a seperate replaceable daughter card or whether it is part of the main motherboard. you will need to investigate this (or send it for a service)
