The login window on my panasonic toughbook is turned sideways. How do I flip it up?

I would check in your instructions because there are a few different ways depending on what model and it will only confuse the issue to mention them.
If you cannot find your manual browse Panasonics web site, you will be able to download one there.

Is it just that the window is upside down??

1. Try pressing Ctrl + Alt + arrow (left, right, up or down) to rotate the screen.

2.Press the hotkeys and arrow keys until you have the desired rotation. This works with most video drivers on Windows XP. If this doesn't work let us know.

you should find those drivers on the panasonic support site---if not, go to driverguide.com---
there are 1,000's of free drivers you can download for free.

According to the following site, your Toughbook has a microphone jack but no built in microphone.

I think your actually having issues getting it to run on the toughbook because it uses different drivers for everything from the Acer computer. If you press F8 while booting up you can choose the option "Disable automatic restart (of system errors or something)". Then when the machine boots up you should get a blue screen giving you an error code like "IRQ_EQUAL_TO_OR_GREATER_X Error: 0x0000005f. You could try to see what the message is trying to tell you to resolve it but the error msg would likely point to the driver that its trying to load that's most likely different from the toughbook you have. I'd suggest getting an external cdrom/dvdrom and install windows from a disc onto the toughbooks hd while its in that toughbook machine.

Your touchscreen is defective. Please contact Panasonic official service center http://heartlandsi.com to arrange a repair. It's covered under warranty.

Finding a complete recovery disc is prooving difficult. i have found a couple of alternatives to getting a complete install on disc, but they do take a little bit more time.

if you have a copy of the windows which you wish to run your system on. which nowadays arent hard to comeby, then you can use this link as a driver and compac software restore disk

however these downloads / cd'a have to be purchased. i really wouldnt bother with it. drivers and apps for compac arent a must have and usually just do things to make the GUI fancey or easy to use. most drivers will be picked up on windows install and the rest wont be hard to track down. a standard windows install is surfice for most things and runs quicker than an install full of tosh little programs.

I solved this on a toughbook. The numlock was activating while windows started even with the regkey set to have it off.

All I had to do was restarting the PC waiting for windows to activate the numlock again during the shutdown process and then hitting the numlock once before windows was done.

Next time the Toughbook started the Numlock kept off!
