Loose Power Cable- can it be fixed?
I have an HP notebook, model G60-535DX. The power cable, when plugged in, is very sensitive to touch. The light easily goes out (the small silver charging light next to the jack). The cable, when inserted, feels loose. SO, I think the jack is loose from the mother board. HP is out of warranty and I am traveling. Can I open case and easily fix this?
1. Test your AC adapter with a voltmeter and figure out if this is bad adapter cable OR bad jack.
If it's bad adapter, replace it with a new one.
2. If it's bad jack, you'll have to disassemble your HP G60 laptop and replace the jack. It's not soldered to the motherboard. You can simply unplug the damaged jack harness and plug in a new one. Take a look at the last picture in the guide I mentioned.
3. Alternatively, you can find laptop disassembly instructions in the official HP service manual. Find your HP laptop and download the manual. Go to parts replacement procedure. In the same manual you can find HP part number for DC jack harness.
Same instructions apply to Compaq Presario CQ50/CQ60/CQ70 and HP G50/G60/G70 laptops.
These DC sockets are NOT a unit soldered onto the circuit board, but are on a flying lead and then plug into an edge connector elsewhere. So do not expect a lose jack to mean the solder connection is broken- as the whole jack case is "floating" from the factory design! ( I took my laptop apart expecting a cold solder joint and it is not connected that way)
The wire leads that are soldered onto the back
Of the jack case may be loose or broken from the jack wiggling around- or the contact pins inside the jack that detect if the peer supply is plugged in etc, may also be worn down or bent out of position. Either way, you can replace the complete assembly by unplugging the unit - no soldering is needed. (unless you see an obvious wire break from the back of the jack case assembly)
I suspect a battery that fails to charge has a bad contact inside the assembly if all wires look intact.
