ok so the first thing you should do is to get to where your PB X connects to the lines and ensure that there is a standing voltage on the lines. usually 50 v dc in the uk. check each line has 50 volts with a multimeter when nthey are not active. if line 3 has no voltage your problem is the line. if line 3 does have voltage at 50 v idle ring the lines out 1 then 2 then 3 foir a analogue line to present ringing bthe voltage increases and is in cadence with the ringing. if again the voltage does not increase during the ringing cycle then the problemn is again with the line. if the line 3 has 50 v idle and increase in voltage during ringing, then the problem is the line interface in the PBX hope that this helps all above is for analogue lines only

I would look at the charging port on the laptop itself. It may be bad or not fully attached to the motherboard. Does the charge indicator light come on? If not, try cleaning it with rubbing alcohol and then slowly moving the charging plug around where it connects to the laptop and see if the light comes on at all. If that doesn't work, you could disassemble the laptop and look at the connection/solder joints. This or similar video's may help in doing that - How to Remove Bottom Bezel on the Toughbook 29

I'm not sure if yours is the same layout as the CF-53 I use. But my F12 button has a picture of a button with light on it. I use FN-F12 to adjust the brightness of the keyboard. Mine goes through 5 brightness levels before returning to off and starting over.

It sounds like the hard drive has given up

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
