when you turn the key on a light on dash goes on and the glow plug relay supplies power to the glow plugs for a certain amount of time, then the dash light goes off and you start the engine.

It is more on a hardware issue. The battery needs to be drained. Once on, let the battery drain and re charge it for 4 hours.

Laptop computers have the advantage being portable and self-contained, but among their drawbacks is a keyboard without a separate number keypad. While for most applications number keypads are unnecessary, they can be useful for data entry. Laptops sometimes provide a number keypad by giving certain keys double duty, allowing them to enter numbers rather than letters when a "Number Lock" setting is turned on. Number Lock, however, can get turned on accidentally, or enabled by an operating system by default, which can really mess up your typing. If typing "M" ends up displaying a "0" on your screen, Number Lock is probably the problem.

Try to locate the function key. On a T-series ThinkPad, it's in the lower left hand corner. It should be labeled "Fn," and the lettering may be blue, green or red instead of white. If your laptop lacks a "Fn" key, use the "Shift" key for Step 3 below instead. Locate the key labeled with "NmLk". On a T-series ThinkPad it shares a key with "ScrLk" which sits on the very top row between the "PrtSc" and "Pause" keys. On other IBM laptops, the "NmLk" key might share a key with "Delete." While holding down the "Fn" key or the "Shift" key, depending on your model, press the "NmLk" key. This should turn off Number Lock and restore your keyboard to its usual state. Number Lock on an IBM laptop is a "toggle" setting. You can turn Number Lock on by following the same steps.

HiPerform a hard resetIf a PC suddenly fails to boot properly, you should perform a hard reset as the first procedure.

1. Disconnect all peripheral devices and remove all USB devices and media cards. You want to test the computer not the accessories!
2. Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds .
3. Reconnect the AC power adapter (but do not connect the battery), Press the Power button,Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a disk drive and fan turning.Hope this helpsRegardsMichelle

The strip that connects both the upper and lower slider is damaged ... replace it

I have managed to fix the problem by doing a software update.
I stumbled across the solution..........I had the phone connected to the computer when I started it in the 'boot loader' screen as opposed to just turning it on. This time the computer recognised the phone was connected and through the motorola software update program I was able to update the software and the phone now works fine.
BTW I did lose all my address book, messages etc.
To start in the boot loader screen hold down the * + # + pwr keys all at once.

The problem may lie in the settings-->System-->Backlight-->Battery Power--> Make sure you check "Turn on backlight when a button is pressed...." I believe this is a firmware bug. Do the same for external power.
