Memory reading I changed the RAM from 256 to 512 in my TC1000 Tablet PC, the computer does not recognize the 512,only 256,anyone has any solution for my problem?

The SD card is not counted as RAM Memory.
RAM memory is included inside the tablet and is not upgradable.

The ram in your tablet is RAM DDR3 512MB.

Firstly, many of your components are highly sensitive to static shock (the poke you get from touching certain things), so take care to avoid exposing computer's components to this.Try changing your RAM\Memory. Or just remove one stick and then try turning it on. If it works, then the stick you removed is causing the problem. If it still doesn't work right after removing one stick, then take out the other stick of RAM and put back in the one you took out to begin with. If you get it to start, then most likely the stick that you have removed is the cause of the problem. Try putting the sticks in different slots (one at a time) as well. Sometimes the slots go bad but not the memory. If you tested the RAM and the slots as described above and it still won't come on, then you may have some more severe problems that may require you to have the motherboard replaced in order for it to work right. Such as, the video chip is malfunctioning (this is affixed to the board and not easy to replace, the chipset is burned out (again, affixed to the motherboard), & etc. Please leave feedback about this solution. Thank you!

The Compaq Tablet PC TC1000? (Marketing Part Number D 70045-236)

Turn the laptop over, you're looking at the bottom. Battery Compartment is to the Right.

To the left of the battery compartment is the Memory Compartment. (The parting line for the memory compartment door, starts to the left of the battery release button)

The Memory Compartment is rectangular in shape. The right lower corner has a half U shaped cutout. (Next to the battery release button)

At the top of this panel, or door, are two Philips head screws. These are removed. The panel is then lifted up at the side the screws are on, SLIGHTLY, then slid forward. (Forward. Away from you)

(There are two plastic tabs at the end towards you. They slide into the body of the laptop, and if the panel is lifted Straight up, these small plastic tabs could break off)

I would like you to download the Hardware Guide for this tablet PC. It explains about the hardware, and also shows how to install ram memory.

(Second one down)

This is a PDF file. Your computer has Adobe Reader on it, which uses PDF files.

I advise letting it download all the way before looking through it, or you may break the download connection.

Page 128 starts with telling you how much is the Maximum Amount of ram memory.
(512MB)

Tells you that there is only 1 Ram slot.

The next page tells, and shows you how to open the Memory Compartment door, then details how to remove,and install ram memory.

well i do have every vista version out in the markit and i can most likely install ultimate vista it has and does it all. you can contact me via email so we kan further deal with ur issue. [email protected]

I am not sure what motherboard you have, but I would suspect that your computer will take at least 2 sticks of 512 MB each.
You didn't say what operating system you are using. If you are using Windows 98, 128 MB is fine. If you are using Windows XP, you should have at least 10x that, or 1GB to run correctly.
You really do need to know how much memory your computer will support, so you can go on the manufacturer's site and look it up or use the manual that came with the computer, if you still have it.

Change keyboard.

You should enable adhoc mode in wireless settings.

TC1000 Password Clearing Procedure
1. Discharge any static electricity you may be carrying, it can burn up your mainboard and it doesn't take much! Remove the battery pack and place it out of immediate reach. you will be tempted to snap it back in later before it should be and this will spoil the work. Read everything before you start so you will understand. Remove the mini PCI communications/ memory expansion slot cover (2 small phillips screws, stick them to a piece of tape. When you reinstall them later, start by turning backwards till you hear and feel the threads mesh, then tighten slowly ... you don't want to strip out the threads on your frame! "Lefty loosey, righty tighty")
2. Remove the RTC battery “Real Time Clock (RTC) Battery” This is the black coated nickel sized battery tucked under the frame edge a little. You may have to remove the RAM if you have the extra slot filled to have enough room to work the RTC battery out. to remove the RAM chip pull the spring arms gently away from both sides at once and it will pop up at a 45 degree angle. pull it straight out. to reinstall it later put it back in at an angle, push it gently in then down to let the arms snap onto it and hold it in place. only goes in 1 way, note the notch. Use a toothpick to lift the black plastic film from the edge of the chip as it always tries to get in the way on reinstall. Have some patience or let someone else do it. DO NOT use any metal tools and be sure to remain static free!
Break or cut a short piece off your toothpick to make it easier to use the squared end to push and work the connector of the RTC battery plug off it's attachment. You may be able to unplug the RTC battery without removing it, your call. It connects at the white connector thats located next to the frame rail that separates the battery compartment from the mini PCI communications/ memory expansion bay. It is between (above) the battery release switch and the thumb lift depression to lift out the battery. Now, hold the power switch in the on position for 30 or 40 seconds to discharge any static. This is a good and recommended practice every once in awhile when batt is out and AC is not connected.
3. Wait approximately five minutes.
4. Replace the RTC battery (or reconnect it)and reassemble the tablet PC except for the main battery, do not install it yet! Remember the toothpick will help you get the plastic film lifted clear of the RAM chip, work it into place at a 45 deg angle and then gently press it down till it locks. DO NOT STRIP out your cover screws, or try to get them super tight. They will strip out your frame, finger snug is enough.

Do not reinsert the battery pack at this time! Thats why you can't reach it!

5. Connect AC power to the tablet PC.
6. Turn on the tablet PC.
All passwords and all CMOS settings have been cleared.
7. Now you can reinstall the main Batt!
Good luck!

Whatever happened? Fixed? still not up? Trashed?
