    I had the same problem, in addition, the touchpad and keyboard would not work. Everything did work in safe-mode. Since the battery was a crappy one anyway, I solved the problem by removing the battery and using the laptop as a desktop.

My IBM Thinkpad won't turn on after improper shutdown.


Always check power supply first. Ensure green/orange charging light appears in the LED bank near the screen bottom when adapter is plugged in. If NOT then charger or battery (or motherboard) is faulty.
A dead battery shouldn't cause a shutdown, so the charger is the first suspect. The yellow power socket can become 'rusty' in some cases so inspect this also. If the contacts inside aren't clean & shiny then try some WD40 after scraping gently with a 1 or 2mm flatblade screwdriver (with the battery OUT). If not even a P.O.S.T. (Power On Self Test - IBM logo)
appears with the CDROM and Hard Drive removed, Try cleaning the memory and swapping its position on the back of the unit. Good Luck.

Black screen when turned onno display


There are several reasons that your Toshiba laptop screen may not come on, even if the laptop appears to be running, and several options you may try to get your screen back up and running without an expensive service call.


Common causes for a blank screen include a backlight that is turned off, a display toggled to an external monitor and improper shutdown errors.


To avoid blank screen errors after your current error is fixed, make sure to follow all instructions in your user's guide to care for your Toshiba computer.


Shine a flashlight directly at your screen and look for an image.

If you see one, this means the backlight on your laptop is off but the screen is still working. This backlight normally turns off only when your screen is closed.


Look for a small metal or plastic pin near one of the screen hinges.

The screen pushes this pin in when it is closed, so if the pin is stuck in the screen closed position, the backlight will remain off.


Tap the pin several times to release it.

You may need to use a small object, such as a pencil tip or straightened paper clip, to reach it on some models.


Monitor Toggle


Press and hold down the "Fn" key if you do not see an image when you use the flashlight.


Tap the "F5" key several times while the "Fn" key is pressed.

This will cycle your screen through the various options that toggle the display to an external monitor.


Attach an external monitor, restart the computer and try this method again if no image appears on the laptop screen.


Click "Start," "Control panel," "Hardware and sound," then "Device manager "using the external monitor if you get an image there but cannot toggle the image back to your LCD.


Select the "Monitor" option to expand your selection and select your LCD monitor from the device list.


Click the "Driver" tab and select "Update" to update the driver, as this error is likely caused by a software driver error.


Force Restart


Press and hold the power button until the computer shuts down completely.


Check the indicator lights at the edge of your laptop to see if the computer is truly off or if it has simply gone into hibernation mode.


If it is off, all lights will be off except the battery-related lights if you have a charger plugged in. In hibernation mode, the power light will blink slowly.


Press the power button to restart the computer again after leaving it off for 15 to 20 seconds. This may fix the problem.


If the blank screen returns or you get a flash of images and then a blank screen, move on to the next step.


Force Power Down


Unplug your laptop from the power source.


Remove the battery by pressing outward on the battery latch and pulling the battery unit completely out of the computer.


Press the power button several times to completely discharge the computer.


Replace the battery and plug the computer back in after about 30 seconds.


Press the power button to turn on the computer.

If you get an error screen upon startup, choose to restart Windows normally.

This error is caused by improper shutdown procedures.


Hope this helps

Getting a CMOS checksum bad error when starting my Acer M5640 Desktop with Windows 7 Thanks Daniel


Solutions to CMOS Checksum Bad Error

The CMOS Checksum Bad Error can be fixed easily by following the listed steps carefully.

CMOS Battery may not be functioning properly

If you suspect that your CMOS battery is not functioning properly, you can easily change it. Before changing your battery, reboot your computer to make sure that the error still exists. If it does, go into your CMOS and write down all of the settings. If all the settings are lost, you can usually retrieve them from your computer manufacturer. Now locate the battery and remove it, you might need to consult your computer's manual or technical support to remove your battery (the battery a flat, shiny silver colored and coin-shaped). Take down the CMOS battery's information such as volt, size, etc. Once you have your new battery, you can replace it and reenter your CMOS settings. If your battery was the cause of the CMOS Checksum Bad Error, you should have solved the problem.

Your BIOS may have been updated

If your BIOS have been updated recently, your CMOS settings may have reset. Make sure that the values entered in the BIOS are correct or simply reset them to the default settings. If you believe that a virus has updated your BIOS settings, run a virus scan and make sure that the BIOS settings are back to the default.

The Computer may not have been shut down properly

Sometimes when running MS Windows, if you shut down your computer without first properly shutting down your operating system, it will corrupt the CMOS settings causing the CMOS Checksum Bad Error. You can easily avoid this error by making sure that you completely shut down your computer properly before turning off the main power. Usually this entails going into the Start Menu, clicking on Turn Off Computer/ Shut Down. If improper shutdown was the cause of the error, you may have solved the issue.

Booting problem


There are usually three main reasons that a CMOS Checksum Bad Error has occurred. They include:
  • CMOS Battery may not be functioning properly. The battery life may have expired.
  • Your BIOS may have been updated (either by user or possibly a virus)
  • The computer may not have been shut down properly e.g. shutting off the computer's main power without first shutting down the computer (MS Windows requires you to shut down your computer before shutting off the power).

My Dell Inspiron 1525 Shutdown Spontaneously


Generally with laps the reason for a spontaneous shutdown is power. Either your battery is low or the transformer for power is going bad or is bad. There is information under the control panel, then power options which show the power settings and a meter to check the amount of power left and what is being used for power. Check those two items and you may fine your problem. Also make sure the battery is properly inserted into the slot, if it is loose a bit of movement may trigger the shutdown.

If either of these work please leave feedback.

Stuck shutting down


Press and hold the power button for 10 seconds and then release it. This will shutdown the laptop regardless of what state it is in. If it still doesn't shutdown then disconnect the laptop from the powersupply and remove the battery. Note that this will count as an improper shutdown. After it shuts don put the battery back in and you should be able to power it up.

No power


Check the user guide to see if there is an "All Reset" procedure for your camera. It is possible that the CPU or a controler in the camera is locked up because of an improper shutdown.

It is also possible that something in the EPROM in the camera became corrupted or by coincidence one of the circuit boards has a failure. Improper shutdown can cause these types of failures in these cameras. In this case, factory service would be required.

Why isn't the charging icon always animated (flashing)?


For Mac users "When you plug your iPod nano into a power source, the charging icon appears?it's a lightning bolt over a battery. Depending on the state of the battery, it may or may not animate (flash between gray and green). In either case, the icon indicates the battery is charging successfully. When the battery is fully depleted, the iPod nano may not appear in iTunes until it has been charged for about 10 minutes.The non-animated version of the icon, shown above, appears when your battery has been fully or nearly depleted of charge. This appears for up to 10 minutes. Note: If your iPod nano is connected to the computer, the computer won't see it until after that 10 minutes has elapsed. After that, you'll see the ""Do not disconnect"" screen. If the charging icon is flashing and your computer doesn't recognize it,Can't see your iPod in iTunes or or the Finder? Remember these five basic suggestions when you run into a problem with your iPod. If one of the following doesn?t help, read on for solutions to specific problems. Reset, Retry, Restart, Reinstall , Restore Reset your iPod. Retry with a different USB or FireWire port. Restart your computer and make sure you have the latest software updates installed. Remove iTunes software and then reinstall iPod and iTunes software from latest versions on the web. Restore your iPod. See ?Updating and Restoring iPod Software? in the user's guide.
