I had a cart with a similar issue that was resolved by replacing the keyboard. 

thanks chris i am thinking the same. thanks for your reply

Could be either the keypad is defective or a loose connection from the keypad.

There is a keyboard test in the System Diagnostics Main Menu. From manual: "Press each key and verify that the key is highlighted on the screen and also displayed at the top of the screen." I'm just not sure if this test covers the power on key, but it's worth a try.

There is also a battery status and testing functions in the same diagnostics menu regarding your battery inquiry.

Procedure to enter the diagnostics menu:

Loading the System Diagnostics
1. Select Main Menu on the Resting screen.
2. Select More.
3. Select System Setup.
4. At the prompt type the word “system”, the password set at the
factory, then press the Enter key. If the password was not changed,
the System Setup menu appears. If the menu does not appear, use
the master password. If the system’s unique password is inaccessible,
create one following the instructions in “Substitute Master
Password” later in this section.
5. When the System Setup menu displays, hold down Shift and press
F5 (Shift + F5).
6. Type prod at the service password prompt.
7. The System Diagnostics menu appears.

Have you checked the 801220-002…BATTERY TRANSITION ASSEMBLY?  Sometimes this can be damaged causing the unit not to charge and have power up issues as well.
