On any Panasonic Toughbook you can rotate the screen as follows: Hold down the "CTRL" and the "ALT" keys and while holding down these two keys press the "UP Arrow" key and then release all three keys. This will reset the screen so it is right side up instead of upside down. Good Luck and regards from: Richard, Authorized Panasonic Canada Toughbook Dealer since 1989. P.S. The arrow keys look like this: The up arrow is the one on the top

I'm not sure if yours is the same layout as the CF-53 I use. But my F12 button has a picture of a button with light on it. I use FN-F12 to adjust the brightness of the keyboard. Mine goes through 5 brightness levels before returning to off and starting over.

The VGA or "Video Driver" for the Panasonic Toughbook CFY4 can be found at: http://pc-dl.panasonic.co.jp/itn/drivers/d_menu_en.html Remember to choose your operating system and then click on the "Download Now" button located on the right side.

From two different websites: The same answer 1) "F-11 seems to have been an emergency hot key for police use" The website: http://forum.notebookreview.com/threads/rubber-illuminated-kb-cf-29.239110/ 2) "The red F11 can be programed to report through police dispach an officer is in trouble. This key only works with Special software used by Law Enforcement." The website: https://groups.google.com/forum/#!topic/toughbook/J__ssDTCm_0 Both these guys gave the same opinion and both seem very knowledgeable. Good Luck!

On ALL Panasonic Toughbook Models, if the screen stays dark I would shut-off the Toughbook and connect an external monitor to the VGA port (15-pin female connector), which is usually BLUE in color. Make sure the monitor is ON first, then turn ON the Toughbook. If the monitor comes on then your problem is the backlight or possibly the inverter of the screen. If no image is shown on the external monitor and the screen stays dark and you cannot hear any startup (ie. Windows) sound, then your video card may be defective. Very few Toughbooks fail this way since they are normally very very relaible but it can happen. Good Luck Regards, Richard - Montreal Based Panasonic Canada Toughbook Authorized Dealer since 1989

yes, but you should be able to get a universal charger with proper output cheap

Panasonic Toughbook PC Laptops usually have very reliable battery pack. When your unit is plugged-in but the Power is OFF, you should see an LED light as follows: RED FLASHING: Means the battery needs replacement. Orange/Yellow Solid: Means battery is charging. Solid Green: Means battery is fully charged. NO Light AT ALL: Means that Battery Pack is missing. There is also a battery calibration utility on all Panasonic Toughbook PC's manufactured since 2004. This is a factory installed software and is only present in factory units. This software may also be downloaded as a driver from the Panasonic Toughbook website as follows: http://pc-dl.panasonic.co.jp/dl/ Check also in the bottom right hand corner under Windows for the battery Icon. This will indicate if the battery is charging, present or not present, and under Windows 7+ will indicate if the battery needs to be replaced or not. Good Luck!
