Battery No Longer Holds a Charge ¶
‘’The battery used to last 2 hours but now it only lasts an hour.’’
Make Sure the Laptop is Plugged in Correctly ¶
Ensure the plug is fully seated. Trace the wire back and make sure the plug is fully seated in the powerblock/outlet.
Battery Fully Seated ¶
Turn over the laptop, release the battery lock and slide the release and pull battery out. Check the metal connectors, blow them out like an old Nintendo game. Then re-insert the battery. Note: Please make sure the computer is off and not plugged in.
Clearing the Battery “Memory” ¶
Fully charge the battery then turn it on, leave it on till it shuts itself off, then repeat 3 times.
Device Does Not Power On ¶
‘’You turn on the switch/press the button and nothing happens.’’
Battery Properly Installed ¶
Turn over the laptop, release the battery lock and slide the release. Check the metal connectors, blow them out like an old Nintendo game. Then re-insert the battery. Note: Please make sure the computer is off and not plugged in.
AC Power Connected ¶
If applicable trace the cord back to the wall, make sure the plug is fully inserted; plug in a lamp to make sure the outlet has power.
Power Switch Operating Correctly ¶
Make sure when the switch is slid to the power on position that you feel the switch detents engage. and that the switch travels the full length of the slide.
Screen Not Working ¶
‘’It seems like everything is working but I just can’t see what’s happening.’’
Make Sure the Function Switch is Not Set to External Monitor ¶
Locate the function switch and the f-key associated with the external monitor setting, press it several times to toggle through the different settings. If that is not the case adjust the brightness and contrast of the screen by using the buttons indicated on the keyboard.
Make Sure Correct Drivers are Installed ¶
If there is an image but it just doesn't look quite right, make sure to re-install or update the drivers. Depending on your OS find the device manager page right click on the Display/Monitor, click on properties, then the drivers tab, click the button labeled update drivers. Allow the OS to look for newer versions of the driver online.
Make Sure Back-Light is Working ¶
If you can see the screen very dimly and only in certain light first try adjusting the brightness settings using the hard keys on the keyboard. If this does not help the most likely cause is that the backlight has failed and you will need to replace it.
Optical Drive Does Not Play ¶
‘’ The computer won’t read any CD’s or DVD’s.’’
Check to Make Sure Disk is Inserted Correctly ¶
Eject the disk, replace the disk in the correct orientation. Note: the label of the CD should be facing upwards.
Check That the Surface of the Disk is Clean ¶
Eject the disk, fog with your breath and use a soft cloth to wipe down the disk.
Ensure the Optical Drive Bay is Fully Seated ¶
Eject the disk and gently pull on the open tray, wiggle side to side if there is excessive motion. If so the drive may need to be firmly pressed back into the laptop fully.
No BIOS POST ¶
‘’ There is no data reading from all the parts of the laptop/ it failed the power on self test.’’
Check for Uncorrupted BIOS ¶
Rapidly press DEL key after power on. This should put you in the BIOS setup screen. If your computer crashes before it gets to this point it is most likely a corrupted BIOS.
Reflash BIOS ¶
If applicable. At the starting screen hit the ESC, F2 or F12 key (whichever pertains to your computer) and from there back up the BIOS, update it and restart the computer. If it does not work on the starting screen then you can look under Hardware and Sound and find it there. Note: Make sure your computer is plugged in or fully charged. Reference this page if you do not know how to update the BIOS: https://aps2.toshiba-tro.de/kb0/HTD9502M... .
No OS Splash Screen ¶
‘’The computer starts and I see the TOSHIBA screen but after that I get nothing.’’
Check HDD Spins Up ¶
Make sure that you can feel/hear the hard drive moving.
Check Proper Boot Sequence ¶
Rapidly press DEL key after power on. This should put you in the BIOS setup screen. Go to the section labeled Boot Order. Make sure that your hard-drive is First in the order.
Verify OS Installed ¶
If the laptop is new to you, you may not have an operating system installed. If you do not place a bootable disk in your Optical Drive and try restarting the computer.
Touchpad Not Responding/Responding Erratically ¶
‘’ The touch pad does not respond, it lags or it moves too quickly. ‘’
Check Touchpad Enabled on Hardware and in Software ¶
Check to make sure that a USB device is not stopping it from working. Make sure that the mouse has not been disabled in the BIOS by checking in the control panel. The computer might not have updated the touchpad correctly or it is a hardware malfunction and you have to replace it.
Verify Clean Touchpad Surface ¶
Make sure that the computer is powered off, take a soft cloth and gently wipe the touchpad off, if that does not work then take a computer safe disinfectant and wipe it down with that.
Recalibrate Touchpad ¶
Enter the control panel, click on mouse utility, locate and click on device setting then follow the directions to calibrate the mouse.
No Sound ¶
‘’ There is no sound coming from the computer.’’
Volume is Up ¶
Press the Volume Up key several times. Note: The volume bar that appears on the bottom of the screen.
Audio Driver Enabled ¶
