How to Reload Windows XP Without Removing Files
Deleting system files, modifying the registry and installing incompatible drivers to Windows XP can damage the integrity of the operating system, rendering it inoperable. Virus infections are often responsible for making the aforementioned changes to a system, but employees who have administrative access to the workstation can make deleterious modifications to the OS as well. Reinstalling Windows XP can repair the OS, but if work-related files are stored to the system partition, all of the data will be erased during the installation process. To reload Windows XP without losing files, you can perform an in-place upgrade, also known as a repair installation.
Step 1Insert the Windows XP CD into the optical drive and then press "Ctrl-Alt-Del" to restart the computer. Step 2Press any key when prompted to load the contents of the disc. Press "Enter" on the Welcome to Setup screen. Step 3Read the license agreement, pressing "PgDn" to scroll down the page. Press "F8" to agree to the terms. The CD will search for previous installations of Windows XP. Step 4Press "R" to repair the selected operating system. The disc will begin reinstalling the operating system to the hard drive without affecting personal files. Follow the on-screen prompts to complete the repair installation. Step 5Log in to Windows XP and sign on to the Internet when installation completes. Click "Start," "All Programs" and then "Windows Update." Step 6Click "Scan for Updates" to search for applicable service packs and hotfixes to reinstall to the OS. Step 7Click "Install Now" to bring the in-place upgrade up-to-date.

Windows XP CD
Tip
Make sure you have your Windows XP product key (found on the CD cover or on the computer case) available prior to reinstallation.
Warnings
If possible, back up your files previous to the installation in case something goes awry during the process.
You will need to reinstall all non-native programs and removable devices after performing an in-place upgrade.
I have had to retrieve the BIOS password from one of these before. It is not an easy thing to get to. You have to first
Build a special 9-pin Serial cable using parts you can find at Radio Shack
Dismantle the laptop
find the correct BIOS chip,
Solder a couple wires to the correct pins of the BIOS chip (without getting solder on the other pins, or damaging something)
Hook it up to another computer via serial port
Do a dump of the information stored on the BIOS chip
Use a hex-reader to decipher the information and display the password within.
Here
is a link to a site that shows you in detail how to accomplish this. It
does work, and I've successfully used the linked method to unlock a X41
of my own.
It sounds like it may not be fully charging.
If the port on the tablet is loose/damaged or the cable/charger is failing, then the tablet may not be charging even though its plugged in.
If you can, try a different cable.
Make sure the charger is the correct one for the tablet! Some tablets require more electrical current then a computer's USB port provides. Same thing applies if you are using a 'phone' charger with the tablet, might not be enough current.
Most USB ports/chargers output about 5 volts DC (direct current), but they can vary in the amount of Amps (A) or mili-Amps (mA) they produce.
FYI - the symbol used to represent Direct Current is straight horizontal line with a dashed horizontal line directly under it.
Most computer USB ports only produce 500mA.
Most phone chargers only produce 1A.
Many tablets require 2.1A or 2.4A to properly charge.
Check with your tablet manufacturer to find out what your specific make/model requires and the look closely at the charger you are using to see what the OUTPUT is ... e.g. 5.2V 2.4A
