A multimeter is a device that tests electrical properties of various devices and components. You use the multimeter to test the voltage of the adapter to see if is working and gives the correct voltage that your laptop requires.

    Have a look at the adapter's label and it will tell you what the output voltage of the adapter.

    If the adapter label says for example 19 volts, connect the adapter to the mains supply, turn the dial on the multimeter to 20 volts DC range and connect to red lead to the multimeter and the black lead to the common on the multimeter. With the red probe place it into the hole on the adapter's connector that plugs into the laptop and the black probe against the metal side of the same connector. Now read the voltage on the display on the multimeter, it should be the same or slightly higher that what is printed on the label. If you don't get any reading then the adapter is dead.

Acer 4320 won't power up


Here below are possible causes and troubleshooting steps of laptop that can't power on, hope it may help:
Possible causes:

1. AC adapter failure.
2. Power jack failure.
3. Motherboard failure.

Possible troubleshooting steps and repair solutions:
1. Test your acer travelmate 4320 ac adapter with a digital multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.

2.It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one. Using a multimeter, test if the power goes to the motherboard through the jack.

3. If replacing the AC power adapter and jack on the motherboard doesn't help, most likely you have a bad motherboard. Replace the motherboard.

My acer travelmate 240 dose not have sound


Ever consider to see if headphone jack works? If this is the case it is possible it is the speaker.

Sound card or similar is possible but an expert should be the only one to look for that.

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."

Acer laptop power problem


Does not switch on from mains.?????????????
PLEASE EXPLAIN..........

Is the laptop lights not coming on when you plug it in? If not refer to the following.

Are you sure that your power plug has not broken loose. You will have to take the laptop apart to find this out. Sometimes the solder joint will come loose. Do not take this laptop apart unless you know what you are doing. The manual can give you step by step directions sometimes. It is not easy to take it apart without breaking the little things. If you do take it apart, take pictures of every step and take notes and even draw picture so you will know where everything goes. You can touch the plug where it is soldered and re-solder the plug. Please be careful. This takes someone with good solder skills to do.
