My tc4200 screen just went dark while in use

My tc4200 screen just went dark on me while I was rotating it to access the keyboard...I've verified it's not the GPU as external monitor works fine...I wonder if it's the switch that turns the screen on/off...does the tc4200 have a physical trigger to turn it on/off? I've ordered an inverter as that's my cheapest start...I really hope it's not the motherboard as I've heard another post mentioned...

Cannot open my laptop


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.

Compaq tc4200, does not have a boot drive, can I attach a USB dev


The TC4200 does boot from a USB device, if you connect the USB device to the system it should detect it right away. You may have to change the boot order/

When you booting and you see the Compaq boot screen press F10 to enter the BIOS
Go into the Advanced Menu, there you will be able to set the boot order.

Hp tablet pc has a blank screen


You're first step should be to plug an external monitor to it to make sure the video card still works. In all likelyhood, the video inverter (located behind the bezel for the screen) went bad and needs to be replaced, but it's good to know whether or not the computer itself is still putting out video

Taskmanager popup


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.

HP tablet PC tc4200 latch fixable?


In a pinch, you can pop the lid open on these by sliding a credit card between the screen and base chassis. Typically when the latch breaks on a tc4200/4400 it will need to be replaced unless it is simply jammed.
