Motion Computing LE1700 power problems

Folks,

I have a Motion Computing LE1700 which I use for Off Road navigation. A very good and sturdy machine.

It has been upgraded to WIN 7 (64bit) and 128GB SSD with 4GbRam, and runs fairly well considering it's age and limited usage - mainly Nav/GPS software.

Problem is - the batteries (internal and external) are dead and will not charge.

I found "new" ones on e-bay, but that did not change the situation. It works fine when connected to Home charger, and Vehicle charger, but dies as soon as I disconnect.

I also suspect the charger connection may be faulty while on the move with the vehicle's vibrations.

Is there a way to operate it without a battery? Is there a way to connect directly to the MB?

I know this is an old post, but, I have a LE1700 as well, did a SSD mod, but curious how you got it to 64 but Win7! As for the batteries, I have a lot of them and believe the internal cells are 18650, and can be swapped out. I'm going to be trying this soon, as my batteries also no longer charge. Also got the bigger, flat secondary battery that goes on the back, and going to attempt to open that too, to see what kind of cells are in it.

Hi @yuvalm56 ,

If you are going to connect straight to the motherboard you may as well fix the charge port as it would involve nearly the same amount of work.

You say that it works when connected to the Home Charger and the Vehicle Charger but not when travelling in the vehicle due to movement, so it most probably is only a loose connection on the port itself.

Here is a video that shows how to repair the port in your tablet. It is shown being replaced. In your case it might only have to be resoldered back onto the board.

Use external power bank that provides 21v output. Available on ALI

I'm more curious as to how you got a 64-bit OS on one of these! I have several LE1600s and one LE1700 that I've swapped the HDD to a larger SSD, but I thought the mobo's hardware limited the OS to 32-bit.

As far as the batteries go, they're easy to open up,just an xacto along the seam and a fine small screwdriver, and patience. There are 4 18650 cells inside, that can be swapped out. The factory ones are decades old.
