20 Most Recent Compaq tc4200 Tablet PC Questions & Answers

You just need to download and install the driver and it should be fine.

Go to www.hp.com and click on support and drivers then check the download drivers button and finally enter in the model in your case TC4200 and this will open a new page. Next select your operating system and you are now at the downloads page.

Download the drivers, save to desktop (its easy to find again then) and then run it and folow the inscreen instructions and reboot if asked to.

You haven't mentioned your operating system so I can't give you any more exact instructions. If you download and install all of the available drivers for your version of windows you can't go wrong. Windows will try to use built in drivers such as the video. These work but the oem driver usually gives you more options and sometimes better performance. The touch driver will either be part of the video or the input drivers dpending on what version of windows.

Let's start as simple as possible:
Do you have a loose connection / glitch at the power-connector? Check and solder (link to manual for disassembly is further down in this document)

To me this looks like a stuck key (not necessary one on the keyboard):

create live-usb-ubuntu:
1. download and burn ubuntu 8.10 to cd.
2. boot _any_ computer with it, connect >1GB USB stick.
3. System --> Administration --> Install to live usb
4. Boot from live-usb-stick that you just created
5. open terminal (Applications --> Accessories --> terminal)
6. paste this: sudo apt-get install xev
7. paste this: xev
8. hover with mouse over white box
9. make sure not to press any keys or move the mouse. Now flip the screen or try to recreate a situation in which the task manager would pop up in windows.
10. what's the output in the terminal window? Try to pinpoint exactly how and when the events are generated.

There should be no event generated, when you physically flip the display (which means you don't have to replace the hinge).
Press every single key you can find on the laptop. Verify that each key generates exactly one event.

If you find that there is a series of events generated without any key pressed, try to clean the malfunctioning key. (Service manual for disassembly)

It might possibly be a broken hinge (20USD). Flipping the display and pressing soft keys (Q, rotate, e) does not generate events in xev. Any other button does.

Which version of Windows is installed. If it is Windows 7, which I would recommend, as long as the Bluetooth device is enabled in the device manager then click "scan for hardware changes" in the action tab and it will automatically check windows update for the latest drivers.

There are a couple of possible causes and solutions... Please give some more info.

Is the hibernation period long enough to allow the TC4200 to cool down or is it just long enough to close the lid and reopen it?

I believe I can give you a definitive answer with more info.

Can you be more specific? Please give us a scenario or even a windows version... Is it a fresh install? Is the hard drive full, new, is it a ssd? Something to with with is helpful!

The latch is magnetic and if it breaks while closed, it will be stuck closed. To open it, you can slip a business card or something similar between the screen and the keyboard at the corner, just inboard of the rubber bumper and slide it across from left to right (I believe) while exerting a slight upward pressure on the screen and this will open it.

Be sure to replace it as soon as you can to avoid breaking the plastic "Screen Alignment Guide Pins" off. This will happen if the screen is not latched firmly and is allowed to rotate while in the closed position. The guide pins are impossible to get, as they are long discontinued. You would have to replace the entire palm rest to have them back.

Please be more specific...

Windows version?

Scenario in which you have forced a device to stop?

Which device you have forced to stop?

The hard drive looks to be dead.

From the little amount of information you have given, it could be several things. One common issue is overheating. -Blocked fan intake/exhaust holes -Dust blanket between the cpu heatsink and exhaust fan. Get the air duster and blow out all around any holes, This is a temporary fix to get you going for a few weeks or more, if overheating is your problem. Thanks.

Most times you remove the CMOS battery your manual can be found on compaq website Manuals for HP Compaq tc4200 Tablet PC

have you tried connecting it up, leave it for say 8 hours and don't use, try it then?

Need more detail! Is all you get, a black screen? Does it go so far into booting then go black screen? Does the hard-drive light flash for more than 10 seconds after switching on. A detailed description of what happens (or doesn't happen, that you would expect to) from the moment you press the power button is needed to be able to diagnose. Your description is like someone going to a garage and saying "it doesn't drive"

The problem could be a damage to the MB by excessive heat produced by Nvidia GPU. The only way to fix this permanently is to take out the MB and reflow the GPU with heat. You can find a video on youtube how to do it. You must take out the piece of gel between GPU and cooling unit and replace it with copper bar or penny made prior 1983 - still made out of copper. Also clean the fan. Use heat transfer paste like arctic cool - not a glue, on both sides of the penny. Install win7. Win7 does not use the coprocessor and will help to ran the notebook cooler. Install speedFan 4.40 - free utility to see what the temp is of your GPU and CPU. If you did good job it will stay around 55C. If your HP notebook is still running check the temp. If the GPU is running 80C or more it will melt the connections on the MB and quit working sooner or later.
