Fujitsu LifeBook N3510 Troubleshooting

When pressing the Power Button, your LifeBook just won't turn on!

Your computer's battery may be drained. Plug your charger into your computer and into an outlet. Your computer should be able to turn on through the connected charger.

If you suspect that you have a bad battery, you may need to get a replacement battery. Try a known working battery on your computer and plug in a working charger. Your computer should turn on. Then try your battery. If it does not turn on then your battery may be faulty.

After troubleshooting the battery: if your computer still won't turn on, you may have a power adapter problem.

To find out if your problem is your power adapter, try using a known working power adapter for your computer. If your computer turns on with this known working power adapter, then your power adapter is faulty and you will need a new one.

If your computer still does not turn on with a working power adapter, then your computer may have an internal problem.

The motherboard may be faulty and require replacement. Replacing the motherboard is expensive and time consuming; it should only be replaced as a last resort.

Your computer finally turns on and makes sound or lights up, but then turns off or freezes!

The RAM may need to be replaced. Consult the RAM Repair Guide for instructions on replacing the RAM.

The computer may have overheated, over the course of its use, due to a fan problem. The fan cools the computer while it is in use, and without it, your computer is susceptible to high temperatures. Damages to the internal parts of your computer may have been caused by excessive heat.

In this case, the fan may need to be replaced. Consult Fan Repair Guide for instructions on replacing your fan.

If only a few keys are not working you may need to clean your keyboard. If your LifeBook has been exposed to dirt or small debris, there's a chance that the particles are stuck under the keys and are causing a loss of key function. You can use compressed air to remove the debris from under your keyboard. If the problem persists, you may need to replace your keyboard.

When none of the buttons on your keyboard are working, your computer may have a keyboard problem that requires it to be replaced.

If the problem remains unresolved, it may be a motherboard problem.

You just inserted in a disc, but your LifeBook won't play it!

Your disc may be in poor condition. Try another disc in your computer. If this other disc plays, then your original disc may be damaged. If neither disc works, then the problem may be your optical drive.

The optical drive may need to be replaced. Consult the Optical Drive Repair Guide for instructions on replacing the optical drive.

You try and connect to the internet, but your LifeBook won't get a signal!

The wireless module is what lets the laptop establish a wireless connection. If you're unable to establish a wireless connection, you may need to re-install the drivers which allow your computer to "talk" with the wireless module. You can find the driver installation instructions here: http://www.pc-ap.fujitsu.com/support/drv...
