Did you open the case on your computer? It may have an open case alarm which is a small switch typically located near the edge of the cover you removed. Make sure the case cover is completely installed, then see if the alarm goes off.

Only getting intermittent power supply when AC adaptor plug in,power can be ma to come on by gentle movement of the connector in the laptop socket?


You need to replace the DC Power Jack on the motherboard, of the LAPTOP.

What is the LAPTOP manufacturer name, and Model Number?

Just to give you an idea of what is entailed;

I have an inverter, then a UPS, as the inverter does not always keep the PC on. The inverter does not power the UPS so it cuts out after a few mins, I then have to take the UPS out of the system until the...


Hello,

As I understand your statement, Your inverter (Powerline 200watt) has the UPS plugged into it, but it is not able to keep the UPS powered on. You didn't mention the size of the load (PC), nor the wattage rating of the UPS, or the batter bank size that supplies the inverter.

It sounds like you are trying to create an electrical system with double redundancy. If this is the case, you are going about it wrong. Most inexpensive inverters will have a Modified Sine Wave output, that the UPS will detect as a poor AC signal, and revert to backup mode, rather than pass the inverter power to the load.

200 watts isn't going to be very much for anything. 200watts / 120 volts (assuming 120vac system) is only 1.6amps or so. The charger on the UPS will likely use this much just to keep the internal battery topped off. As the PC is turned on, and the battery charger is doing its thing, there now exists an overload at the inverter. The inverter will respond by trying to increase its output by lengthening the pulses in the MSW waveform. The UPS then sees this, interprets it as bad power, and kicks into backup mode.

Since the powerline inverter is obviously a 12volt unit (cig. lighter plug), then check the battery configuration of the UPS itself. If it is 12volts as well, then you may be able to connect the UPS directly to the batteries that were powering the inverter. Note that some modification to the UPS will be needed if there external battery connections are not already present. Even then, there is no guarantee that the charger in the UPS will be able to charge the internal plus an external battery bank.

Since the battery that powers the inverter is likely larger than that of the UPS, why not run the PC directly off the inverter itself and forgo the use of the UPS altogether?

I'm afraid I cannot comply with your wishes, as there are copyright laws governing this, for one. (For existing circuitry)

Two, there is the liability issue. Take for example that I design the requested circuit, give it to you freely, and you or someone in your group is injured using my circuit.

Will state that this is a basic circuit design. I believe that if you 5 put your minds together, you can build this circuit.

Charging indicater light is on but will not power up.


Take out the battery from the laptop and only hook up the ac adaptor and if you get no power to it and still can't turn it on an knowing that your ac adaptor is good, then the motherboard is bad and would need to be replaced.

Run a jumper wire between your Green wire on your 20/24 port plug that would hook to the mainboard and one of the black wires in the same plug. I would put a pushbutton or switch in between the Green and a Black on that plug. You may need to put a load on the power supply like an old hard drive or a CDROM. Plug your power supply in and you will notice the fan turning. Use your multimeter to test for different voltages on the connectors. You should get +/- 12, 5, 3 Volts.

I just went into my basement and tested this out and it works great.

Enjoy
