Question about Compaq tc4400 Tablet PC

1 Answer

My screen on the HP tc4400 seemed to be black until I looked at it under a light and discovered that the menus were there, but I couldn't see them. It was working fine before, so I rebooted it, but the same problems was there. I did try to brighten the screen, but to no avail. There is a possibility that a button could be stuck that makes the computer think that the lid is closed, but how do I troubleshoot that? Is there anything else that I could try?

Of that vintage, could be the back light bulb have burned out or the power supply to them. I'm surprised the HHD is still running on that year model. For the price you can pick one up for on ebay I would replace the the laptop. If you ever have taken one apart and put it back together its an amazing amount of work (see you tube). And while your mashing it all back together there is a good chance it will all short out and be a wash. Put a external monitor on it does it light up? Either way I would get my files off I want off the drive it maybe the end.

SOURCE: Disable TC4400 auto rotate

First in Control Panel -> Tablet and Pen Settings, select Display Tab, then click on Change button next to Sequence. I set 1 as Landscape - Primary, then 2-4 as None.

Second, Go to Control Panel -> HP Quick Launch Buttons -> select Preferences tab -> uncheck the checkbox that says, "Enable Automatic Mode Change"

This worked for me!

Hello,

First you need to check if you did not have any flash drive or device attached to your laptop when you turned it off. Because if you do, your system will not booth completely, you will only be having a black screen, and to solve that, you just remove your battery and insert in back then try to turn it on.

Ensure you have the battery fully charged. Then turn it on. If that does not help, then the problem could be a hardware problem, which could be that the module is faulty and the screen is not lighting up or the hard disk is disconnected or the RAM is not connected properly.

The module is like the flex on the laptop that assists the information from the motherboard be read on the screen. So if it is faulty then you will not be able to see anything.

For that, you need to open it up and replace the module. If it is the hard disk, just tighten the connection and the RAM too, then try to couple it back together and turn it on.

Try to hold down control+alt+delete to see if the task manager comes up, if it does, then you know it is not the module, then you select task manager and run an operating system disk, to format your hard drive and run a new operating system.

These are a list of most likely problems that can affect the screen of your laptop.

If you are not familiar with such technical activity (loosening the laptop), i will strongly advice you seek technical assistance from a professional, to avoid shock or further damage in the unit.

Take care and good luck

SOURCE: This makes me feel really stupid, but here

The start menu is activated by clicking a globe (sphere) at the bottom of the screen on the left side. The globe contains the 4 Windows colors. If for some reason you cannot find it, you can still press the Windows key located between the ALT and the Fn key, on the left of the keyboard.

How do you know the battery is good? does the multimeter really read more than the battery should give, according to what is printed on it?
A 3,7 volt battery, should give at least 3,8, wham not connected. A 7,2 at least 7,4. Because the printed voltage should be on the connector, when you are discharging the battery.

When your charger is blinking, it could indicate the battery is not well. The Ri can be to high or something else, is wrong, and that is ht the charger won't or can't charge.

Well, you will have to try harder to remember it. Failing that, you will need to take it to an HP certified Service Center to have the password erased.

To reset the BIOS password read the information from this link.

In case of your HP TC4400 laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper.
