Chapter 6 Troubleshooting TOSHIBA has designed this computer for durability, however, shouldproblems occur you are able to use the procedures detailed in this chapter to help determine the cause. All users should become familiar with this chapter as knowing what might go wrong can help prevent problems from occurring in the first place. Problem solving process Resolving problems will be much easier if you observe the following guidelines: Stop immediately when you recognize a problem exists as taking further action may result in data loss or damage, or you may destroy valuable problem related information that can help solve the problem. Observe what is happening - write down what the system is doing and what actions you performed immediately before the problem occurred.Make a screenshot of the current display. Please also be aware that the questions and procedures described in this chapter are meant only as a guide, they are not definitive problem solving techniques. In reality many problems can be solved simply, but a few mayrequire help from TOSHIBA Support - if you find you need to consult others, be prepared to describe the problem in as much detail as possible. Preliminary checklist You should always consider the simplest solution first - the items detailedin this checklist are easy to fix and yet can cause what appears to be aserious problem: Make sure you turn on all peripheral devices before you turn on the computer - this includes your printer and any other external device you are using. Before you attach an external device you should first turn the computer off, then when you turn the computer back on again it willrecognize the new device. Make sure all optional accessories are configured properly in the computer's setup program and that all required driver software has been loaded (please refer to the documentation included with theoptional accessories for further information on its installation and configuration). User's Manual 6-1
Check all cables to ensure they are correctly and firmly attached to the computer - loose cables can cause signal errors. Inspect all connecting cables for loose wires and all connectors for loose pins. Check that your disc media is correctly loaded Always try to make detailed notes of your observations and keep them in a permanent error log - this will help you to describe your problems toTOSHIBA Support. In addition, if a problem recurs, the log you have madewill help to identify the problem faster. Analyzing the problem Sometimes the computer will give you clues that can help you identify why it is malfunctioning. In view of this you should keep the following questions in mind: Which part of the computer is not operating properly - keyboard, Hard Disk Drive, display panel, Touch Pad, Touch Pad control buttons - as each device will produce different symptoms. Check the options within the operating system to ensure that its configuration is set properly. What appears on the display? Does it display any messages or random characters? Make a screenshot of the current display and, ifpossible, look up the messages in the documentation included with the computer, software or operating system. Check that all connecting cables are correctly and firmly attached as loose cables can cause erroneous or intermittent signals. Do any indicators light, if so, which ones, what color are they and do they stay on or blink? Write down what you see. Do you hear any beeps, if so how many, are they long or short and are they high pitched or low pitched? In addition, is the computer making any unusual noises? Write down what you hear. Record your observations so you can describe them in detail to TOSHIBA Support. SoftwareThe problems may be caused by your software or disk. If you cannot load a software package, the media may be damaged or the program might be corrupted - in these instances try loading another copy of the software if possible. If an error message appears while you are using a software package you should refer to the documentation supplied with it as this will usually include a problem solving section or a summary of error messages. Next, you should check any error messages against the operating system documentation. User's Manual 6-2
HardwareIf you cannot find a software problem, you should then check the setup and configuration of your hardware. First run through the items in the preliminary checklist as described previously then, if you still cannot correct the problem, try to identify the source - the next section provideschecklists for individual components and peripherals.Before using a peripheral device or application software that is not an authorized TOSHIBA part or product, make sure the device or software canbe used with your computer.

If the battery still does not charge, you should check that the power outlet the AC adaptor is connected to its supplying power - this can be tested by plugging another appliance into it. Check whether the battery is hot or cold to the touch - if so, it will not charge properly and should be allowed to reach room temperature before you try again. Unplug the AC adaptor and remove the battery to make sure its connecting terminals are clean - if necessary wipe them with a soft dry cloth lightly dipped in alcohol. Connect the AC adaptor and replace the battery, taking care to ensure that it is securely seated in the computer. Check the DC IN/Battery indicator - if it does not glow, allow the computer to charge the battery for at least twenty minutes. If the DC IN/Battery indicator starts to glow after this period, allow the battery to continue to charge for at least another twenty minutes before turning on the computer. However, if the indicator still does not glow, the battery may be at the end of its operating life and should be replaced. However, if you do not believe the battery is at the end of its operating life, you should speak to TOSHIBA Support.Battery doesn’t power the computer as long as expectedIf you frequently recharge a partially charged battery, the battery might not charge to its full potential - in these instances you should fully discharge the battery and then attempt to charge it again.Check the Power saver option under Select a power plan in the Power Options .
