Problem:touchpad is not working after change the motherboard.defaulting 840 g1 motherboard at kit.now replace 840 G2 motherboard.its suitable with kit.but touchpad subboardconnector(fingerprint board) is differ.its 40 pin connector.old is 20 pin connector.remove and attach new connector.connecting cable via touchpad.its working properly Hp 840 G1 Subboard not working: problem:daughterboard (usb port,vga port) not function and also […]

Problem: very slow.its too longer to set desktop.and unable to work properly.wait for process for mins.its too down.defaulting 4gb ram,1tb hdd .and uses win10.how its fast.new software is updating every day.its too difficult to manage of config. solution: extending 12gb ram .now its too better than before.must to keep ram accordingly os .otherwise getting too

Problem:Laptop is function.can see the visual externally connecting port.but no vision on display.display not illuminating ,no light.observe the motherboard complete.no damages .current flowing well .also signals.crosscheck with cable.cable looks good. solution:seen the same problem past year ago.strike to replace cable and set .visioning.cable has damaged internally.

problem:its very bad condition after damage.rear camera disappear.fingerprint strip tearing.charging port bent,display smashed by accident. solution:fixing rear camera fresh.changing the fingerprint strip and connect with button.making straight and set the charging port.finally cut the damage screen and thrown.situated the display for vision.make it for work condition.

problem:laptop not function.if join adapter .light is gone.notice the motherboard.mainvoltage track is getting short circuit. keypad particular keys are not working.no interception while working its smooth. battery bulge .touchpad not function properly.no battery backup for usage.its troubling without connect adapter. solution finding the mainvoltage track and remove the capacitors voltage divider section.its clear.no blocking voltages.

problem: No raise battery charger.to keep connect 4hours.its not rise,down.its indicating plugged in charging but no action.once inspected the battery.batteries are not flat.its uneven,cause is battery is damage(bulge).difficult for original battery and also expensive. solution: offered affordable cost of battery.refix and charging .its charging and discharging routine.
