    Re: not switching

    Any recent mishaps with your Compaq laptop, such as dropping it on the floor? Does that model have a power led at the jack?
    sig files are for morons

      not there is no mishaps or drop on floor , it work with battery alone when i charge the battery some where it work but with charger is not working .

        Re: not switching

        So it doesn't work with the adapter at all?

        Schematic: http://lqv77.com/download/546/

        Power circuitry is on page 31. Starting at DC JACK in the upper right corner I would check all the components between +VA and +VIN. I suspect the MOSFET PQ48 is open.

            Re: not switching

            check the pu4 chip and the pr199(220 ohm) resistor near the battery connector .also check pr183 resistor near the memory slot.

                  check the pu4 chip and the pr199(220 ohm) resistor near the battery connector .also check pr183 resistor near the memory slot. have check all what you gave me but still not switching, when i lifted the PR199 there will not be any voltage at battery terminant. i don't know what to do again.

                      Re: not switching

                      the pr199 should have 22ohm value at your multimeter not 220 sorry.

                        Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
                        by sam_sam_sam
                        I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

                        One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

                        Modification to a ZD-987 desoldering/soldering station using a external switching power supply
                        by sam_sam_sam
                        I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails

                        I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...

                        Panasonic switching power supply daughter board has two 27uf @ 50 volt capacitors which I do not keep in stock
                        by sam_sam_sam
                        I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow

                        This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board

                        After all of...

                        DVR camera recorder switching power supply capacitor failure really
                        by sam_sam_sam
                        These cheap non brand capacitors at it again

                        Last night we had a power outage [ long drawn out trying three to come back up before going out completely ] and when I went to turn the DVR camera recorder back today no go 3 bad capacitors ( one capacitor no ESR reading on DVR board the other 3 capacitor on the power supply board over 40 ohm this is not a misprint ) on the external switching power supply and one capacitor on the DVR camera recorder board where the power supply that goes to the hard drive disk is

                        Used a Ring tester to troubleshoot a switching power supply that has a blowed fuse
                        by sam_sam_sam
                        I found this switching power which has a blowed fuse checked diodes which were still good out of circuit checked main filtering capacitor with an ESR meter 220uf@450 volts 0.15 value which to me seem bad but maybe not but without these items not in the circuit because I have about 8 ohm on the output of the capacitors so I removed the switching power supply transformer and checked it with a ring tester and all but one winding showed good all others either showed two red lights or no lights on and one winding had all lights on which was the only one that was good

                        One other check that...
