A very good way to do this is to compare your laptop voltage & ampere requirements (written on a sticker on the bottom of the laptop) with the voltage & ampere ratings of the power adapter. Voltages should be the same, or the power adapter's voltage about up to 0.5 volts more than the laptop's voltage rating. Amperage of the power adapter should be at least equal to or greater than the laptop's rating. It should never be less than the laptop's rating.

Laptop does not work off mains and battery does not charge


Just check the power connection from the AC going to your laptop if the power adaptor of your laptop are working. Note; you only know that the power adaptor was working if the LED (Light Emiting Diode) was light because the power adaptor are have the LED to see it that they are working normally. If the power adaptor working normally their was a problem of the power supply inside your laptop and need to be repair by the electronic service center. But if the power adaptor are not working the problem are in the power adaptor. I recommend that you replace your power adaptor and bring it to the computer store to check its type and model it is because only same type or model of that power adaptor to be replace.

My acer aspire 3000 laptop goes off automatically. i cant even format because it goes off when i start.


You may have a faulty battery or bad power adaptor chord. Try taking the battery out and starting it just plugged with the power adaptor. If it still goes out, then try with battery and no power adaptor.

I cant connect just one network


Be sure that your wireless network is working
Check your wireless router settings
Check if you see any other wireless network available on your computer
Test connection, see if you pulled an IP address
Go to the Windows desktop
Select Start then Run
In the text box type: cmd (WIN98/SE type command)
At the command prompt type: ipconfig
4. What does it read as the IP address?
* If it reads 192.168. something dot something then you are pulling
an IP address and are connected to the network. The problem is
software related, check your firewall, and wireless card configuration.
Also check any WPA or WEP encryption keys. Check with the respective
manufactures.
* If it reads 0.0.0.0 for the IP address you are not connected to the network.
* Check your connection configuration and the adaptor.
* Check with the respective manufactures.
STEP TWO/ Basic troubleshooting continued....Testing the adaptor
1. Go to Windows desktop
2. Select Start then Run
3. In the text box type: cmd (WIN98/SE type command)
A DOS window will open.
4. At the prompt type: ping 127.0.0.1 (reserved IP address for all adaptors)
5. Check the line that reads "packets sent = 4, Received = 4, Lost = 0
A. Zero is good, the adaptor is working. Again check the connection
configuration,and the adaptor configuration.
It may be a power issue especially with older or less expensive computers
or wireless cards.
* Check the antenna location, are you inside or outside, look for interference.
* Check with the respective manufactures.
B. If it reads all 4 packets lost, the adaptor is not functioning.
* Check and update the drivers, Contact the respective manufactures.
* If it shows any number of packets lost (you are dropping packets)
it is an adaptor or signal strength issue (generally form the laptop side,
not being able to reach back) especially with older or less expensive
computers or wireless cards.
* Update the drivers
* Check antenna location, or distance from the signal
* Contact the respective manufactures.

Laptop will not turn on.


plug it into the wall , most newer laptops will have a power boost while plugged into AC.
check your power cable receptical on the back of the laptop, these are notorious for getting loose.
check the cable on the ac adaptor, these are bad for getting breaks that you cant see in them (run your hand down the cable physically and fell for any breaks while unplugged, then do it again plugged in and watch for lights to flicker on the computer.
look for the power light on the laptop to come on when you plug the adaptor in. if you get a light on the adaptor and on the computer, then the adaptor isnt the issue.
the next step is checking the power button and power supply.. post what your results are here and we'll move to the next step if not resolved.
Regards!
