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.


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.


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.

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.

How to Maintain and Extend the Life of Laptop Batteries

Laptop battery is one important component that must be considered in use. Many laptop users admitted the batteries drop and not durable when the laptop is still fairly young age.

How to treat the batteries to make it more durable and can be used much longer? Learn some tips that are mixed following.

Set the battery power

In Windows there is such thing features power options. Through this feature you can adjust the power consumption of a laptop. The trick is very easy. Click the Start button, then open Control Panel and then double-click Power Options icon. Will appear a dialog box with a Power Option Properties. Then select the Power Schemes tab. On the drop down menu will have six options, namely Home / Office Desk, Portable / Laptop, Presentation, Always On, Minimal Power Management, and Max Battery.

Try click on one of six choices. Setting the turn of the monitor, hard disks, System standby, or System hibernates time will vary, depending on the option you choose.

If you want a more durable battery, you should choose 'Max Battery'. This option will save battery usage because it only requires a minimum processor speed such as to read the documents or check e-mail. Max Battery will affect the speed of the laptop in the sense of a laptop's performance will decrease.

Do not let any device 'parking' on the laptop when not in use

Often, allowing laptop users have the device plugged in the laptop - whether it's cable digital cameras, USB memory stick, PC Card - though such devices are not used anymore. Make sure the appliance is unplugged from the laptop when not in use because it will drain battery power.

Notice the use and recharging of the batteries

Do not half-hearted when to recharge the battery. Charge up to full 100 percent. If the battery is running low, the rechargeable battery back up to full but do not wait until the battery is completely empty. This will make the battery capacity to work well.

To note again, remove the battery from the laptop if you do not use the laptop for a long time. Would be better if the laptop plugged directly into the adapter if you will work in a long time.

Reduce the brightness launch that the LCD will eat battery power. Therefore you are advised to reduce the brightness of a laptop as minimum as possible but still comfortable to the eye.

Use the Screen Savers 'Blank'

Screen saver is turns out to drain the battery. Therefore, use a screen saver 'Blank'. The trick, right click on Desktop and select Properties. It would appear the Display Properties dialog box, then select the Screen Saver tab. On the drop down menu there are a lot of screen saver options, including FlowerBox 3D, 3D Flying Objects, 3D Text, Blanks, Marquee and so forth. You are advised to choose 'Blank' and set the time waiting (Wait time) up to 2 minutes and then click OK. This step will make the battery more efficient.

Reduce resolution

Another way to make the battery last longer is to reduce the screen resolution and number of colors used in laptops. To reduce it, you can right click on the Windows Desktop and select Properties. In the Display Properties dialog box select the Settings tab. Then set the resolution slider by pulling it to the left to reduce the resolution. Then in the drop down menu select the color quality (color quality) is lower, and then click OK.

Turn off Wi-Fi

Wi-Fi certainly participate actively consuming the battery consumption. If it does not intend to take advantage of wireless access, or to the Internet, make sure the Wi-Fi in the dead so that batteries last longer.

Battery can be used to power computer. Plug cannot. Tried a different power plug from a different computer with around the same voltage and whatts, but still didn't power. This is a DC in power plug...

The problem is most likely the DC connector in the computer. I have replaced many of these. Normally what happens is the connector is stressed by moving the computer while plugged in stressing the connector. It could also be the DC converter board but .... that would probably affect battery operation also.

To replace the connector, you have to completely disassemble the system down to removing the main board.
