Re: Error 0271

Sounds like it is asking for the power supply to be plugged in before it can start, which indicates a bad Battery, if you are allready plugging in the power supply unit, you may also have a bad or wrong power supply unit,(check that it is set too the correct voltage setting for your country too either 120V or 240V.) Possibly you know someone with the same working laptop so this can be verified by using thier working Battery/powersupply unit or as an alternative can both your battery and power supply unit be taken to a computer or electronics outlet store for simple bench testing before deciding on replacement. Lastly it may be a powersave mode or setting that has been activated before the last shutdown in this case press and hold the power on switch down, until all the lights go out. Leave it turned off for 30 seconds and restart. Press the esc or delete button on startup (before any screen info comes up)and adjust the power save mode setting in this systems bios.

What is small blue flashing light next to power button

Depends on the laptop model but normally but it could be one of three lights. First, the disc utility light (tells you when your hard drive is in use, either reading or writing data). This light normally looks like a square, 2 or 3 circles stacked on each other or a small cylinder. The next type of light is could be is your wifi light. This light tell you whether the computer wifi is one or off or if it is transmitting data. Normally this like looks like an antenna with semi circles coming off the top of it like radio waves. Lastly, it could be your battery light showing you whether the laptop is charging, or charged. Normally this light is shaped like a battery and may have a little lightning bolt in the middle of it. Without know exactly what the light looks like, it is hard to say but these are the three most common lights.
Good Luck and vote for me if this answer helped you out. Cheers.

Where or how do I find the wireless switch?

On the front of the laptop there is a Bluetooth button, and a wireless button.

On the front edge of the laptop, starting from the Left;

Speaker, Bluetooth button, Wireless button, Power indicator light, Battery indicator light, Microphone-In jack, Line-In jack, Headphones jack, Speaker.

The Bluetooth button has a light in the middle of it. If the light is on, Bluetooth is enabled.
If it is on, turn it off. (Push the button in, let go. The light should be off)

The Wireless button, also has a light in the middle of it. If the light is on, wireless is enabled. Be sure it is on.

During cleaning the virus out, the Bluetooth, and wireless LAN driver may have been corrupted.

Here is Acer Support, and the Drivers Download page,

On this page you are going to find the wireless LAN drivers, for your Acer Travelmate 4200 PC Notebook.

1.In the Select Product Family box, Left-click on Notebook.
Wait a second, the next box will come up.

2.In the Select Product Line box, Left-click on

3.In the Select Product Model box, scroll down, and left-click on Travelmate 4200.

Use the blue bar, on the right side of the Driver file name box, and scroll down.

You will see there are 3 wireless LAN drivers listed.

1.Wireless LAN - Atheros
2.Wireless LAN - Broadcom
3.Wireless LAN - Intel

Left-click on the orange box, to the left of the appropriate wireless LAN driver you need.
(Orange rectangle with down arrow pointing to a line)

A small window will come up. There is a circle to the left of - Open with,
and a circle to the left of - Save File.

Left-click on the circle to the left of - Save File.
Now go down to the right, and click on OK.

This file will either go to your Documents folder, or it will go to your desktop screen.

In either place, when you see the file name, Double-click right on it.
The Installation Wizard will come up.
Click on Next, Next, and Finish.
(Bottom of each window)

Restart your computer.

To know which wireless LAN driver you need, (Atheros, Broadcom, or Intel), go to Device Manager.

1.Left-click on Start, (Vista logo button)
2.Left-click on Control Panel
3.Left-click on System and Maintenance
4.Left-click on Device Manager

(If you are prompted for an administrator password, or confirmation, type your password)

When Device Manager loads, look at the file tree before you.
Go down to - Network adapters, and left-click on the + sign to the left.

Across from wireless LAN you will see the name.

Gateway laptop will not power on

Sounds like to me, that you do have power going to your computer(other wise your lights wouldnt be on), but that your hard drive is dead.

You can take it to a computer shop and have them replace your hard drive.

Are you a computer whizz? (do you know a lot about computers like me?)

Could be the Cpu fan (Central Processing Unit)
That could be lethal to the laptop.
Just as well it's a IBM other wise . . .
As for the error it means the time and date are not set.
soloution: run the bios setup utillity to reset time and date.
