2 Verify that the AC adaptor is the correct unit for your device model. The device may not be able to start from an AC adaptor that is rated for less current (amperage) than the device requires, even if the rated voltage is correct, and the plug fits correctly in the DC-IN socket.

The labels on the bottom of the device and the AC adaptor show the specifications for voltage (“V”) and current (“A”) for each device. The voltage level must match exactly. The amperage rating of the AC adaptor must be equal to or greater than that required by the device.

3 The battery may need charging, may be depleted, or may be defective. With AC power connected, turn the device on, and then leave the device running for several hours, which will deliver a slow, steady “trickle-charge” to the battery. Once the battery has been tricklecharged, it may begin working correctly again.

If the trickle-charging does not prove effective, you can connect to Support Online by going to Toshiba support at


The battery light is blinking when the device is on.

If the battery light is blinking when the device is on, this indicates a power mismatch. Do the following:

1 Check the OUTPUT specifications on the AC adaptor

(for example, DC 19V – 3.95A)

2 Check the INPUT specifications on the bottom of the device.

The output specifications of the AC adaptor must match the input specifications of the device.

3 If the specifications do not match, locate and use the AC adaptor that shipped with your device. If the specifications do match, contact Toshiba. See

“Contacting Toshiba” on page 127 .

The Windows

Once you are familiar with your device and used to the way the operating system responds to your work routine, you can easily detect if the operating system is not working correctly.

For example:

The operating system fails to start after the initial startup appears.

If Something Goes Wrong

❖ The operating system takes a long time to start.

The operating system responds differently from the normal routine.

❖ The screen does not look right.

Unless a hardware device has failed, problems usually occur when you change the system in some way such as installing a new program or adding a device.

If you experience any of these problems, use the options in the Startup menu to fix the problem.

Using Startup options to fix problems

If the operating system fails to start properly, you may need to troubleshoot the Operating System and/or its settings.

There are several options to choose from depending on the severity of the problem and your level of expertise with computers.

If Windows ® fails to start properly twice, the Windows ® Boot menu will launch. To enter the Boot menu manually:

1 Press Ctrl , Alt , and Del simultaneously (once).

2 Press the Power button in the lower right corner of your screen.

3 Click or touch the Restart option from the menu.

4 Click or touch Troubleshoot from the menu.

You now have several options:

Refresh your device

Your files and personalization settings won't change

❖ Your device settings will be changed back to their defaults

❖ Your Apps from the Windows ® Store are retained

❖ Apps you installed from discs or Web sites are removed

❖ A list of removed apps is saved to your desktop

For more information, see

“Refresh your PC (with user’s data)” on page 42 .

The Windows

Reset your device

❖ All of your personal files and apps are removed

❖ Your device settings are changed back to their defaults

For more information, see “Reset your PC” on page 44 .

Advanced options

Choosing this option presents you with another set of options:

System Restore

System Restore allows you to use a Restore point to return the device to a state at which it was performing properly. Restore points are created:

❖ When new hardware or software is installed

❖ Manually by the user

System Image Recovery

Windows ® will “Recover” the Operating system using a specific image provided by the user.

Automatic Repair

This feature automates the repair process. The Operating

System will automatically look for problems and repair them if possible.

Command Prompt

The command prompt is a very powerful tool for advanced users.

Startup Settings

In previous Operating Systems the majority of the options found on this menu were available by pressing the F8 key during the Windows ® boot process:

❖ Enable low resolution video mode

Restarts Windows ® using your current video driver at low resolution. This allows you to reset your display settings in the event they have been improperly set.

❖ Enable debugging mode

Starts Windows ® in an advanced troubleshooting mode

If Something Goes Wrong

The Windows

❖ Enable boot logging

Creates a file that lists all the drivers that are installed during startup

❖ Enable Safe Mode

Starts Windows ® with a minimal set of drivers and services. If the device starts and runs in Safe Mode, you will know the Operating System is most likely working properly and that you should look to third-party applications or drivers for the source of your problem.

❖ Disable driver signature enforcement

Allows drivers containing improper signatures to be installed

❖ Disable early-launch anti-malware protection

Allows drivers to initialize without being measured by the

Anti-malware driver

❖ Disable automatic restart on system failure

Prevents Windows ® from automatically restarting if an error causes it to fail. Choose this option only if

Windows ® is stuck in a loop where it fails, attempts to restart, and fails again repeatedly.

Internet problems

My Internet connection is very slow.

Many factors contribute to the speed with which you can surf the Internet. They include: network speed, network conditions, time of day (when everyone else is surfing, your access can be slow) and popularity of the sites you are trying to access. If accessing a particular site is very slow, try later.

My browser cannot find the URL address I typed in.

Make sure you separated the domain names of the address with the forward slash (/). Check the spelling of each name and the syntax of the address carefully. A single incorrect letter or missed character will make it impossible for your browser to locate the site.

My browser cannot find a site I bookmarked.

The World Wide Web is constantly changing. A site you bookmarked yesterday may not be available today or its server may be down for temporary repair. Try again later.
