Asus k501 dc jack repair how to


You have to take the laptop apart to fix it.

Maybe your DC Power Jack which is where the power cord plugsinto the computer is bad. Take an ink pen and push the tip inside thejack and see if the little pin wiggles, if so the jack is bad. You'll have totake the laptop apart to fix it. Most times it is soldered onto themotherboard, so you will have to desolder the old and solder a new one.

My compaq presario r3000 wont charge. its plugged in but when i unplug it it immediatly turns off. the battery life constantly says 0%. it wont drop from that or get any higher. in the bottom right hand...


Sounds like the battery, had similar problems.. if you purchase a new battery make sure you get the right kind there are two types, an 8 cell or 12 cell..

The fix for my pressario involved completely stripping it and soldering 3 pins on the power connector on the mainboard.. not difficult but no mean feat.. now works perfectly (with the inclusion of a 12cell battery)

I have a HP Compaq Pressario R3000 laptop that will not turn on. I recieved a message that the batter was low even though it was plugged in. I bought a new plug, still didn't turn on. Bought another...


This seems to be a common problem for this model. Some have reported a loose (or dry) solder connection on the mother board where the power socket is attached. Does it seem to work if you push the plug in harder, even for a second? . You should read this thread... http://www.tomshardware.com/forum/50946-2-compaq-presario-r3000-power-cord-issue It may not be your particular issue, but there is a likelyhood that it is. If you are not handy with delicate work, or a solder iron, I suggest a laptop repair shop. Maybe copy or print a part of the thread to clearly indicate what you want. Good luck

Faulty connection for AC power adapter on an 8 month old yamaha digital keyboard psr-e413


If the adapter is faulty I recommend replacing it with the exact one for your keyboard. Any Yamaha music dealer should have one. If it is the jack in the keyboard that the adapter plugs into that is faulty it can be fixed. It is soldered to the circuit board and the solder joint has likely failed. You will have to carefully disassemble the case and maybe take the circuit board out if the solder side isn't accessible. Once you can see the solder joint wiggle the jack to see where the break is. You will need to resolder it. If the jack is broken ( the center pin in the jack sometimes breaks) you will have to desolder it and take it to a good electronics store to obtain the correct replacement and then solder it in.

How do i get my hp pavilion zv5000 to run on ac power only. it will only run on the battery.


Zv5000 Laptops are plagued with problems related to the jack on the back of the computer. After prolonged use the jack tends to make the solder joint loose. Jacks can also go bad. The solution would be to check if the power comes on momentarily when wiggling the plug in the jack, if the power comes on intermittently then chances are you have a loose solder joint and may need repaired by a qualified tech. Fortunately, for the technically savvy this may be done carefully provided the proper static sensitive precautions are taken, due to the fact the computer must be totally dismantled to get to the jack and properly inspect the solder connections and repair or replace the jack. Silver heat sink compound must also replace the silicone on the processor ( one dab and compress, do not spread compound!) The jack need should it be replaced can be found on Ebay

The pc not turn on, no power


It might be an issue with the adapter, the battery or the AC jack on the motherboard. First up see if your AC adapter's power LED comes on when plugged into a power source. If it does, then check if the Lights at the front of the laptop indicate that the adpater is plugged in. If they light up then it means that the laptop's battery is faulty and needs to be replaced. If the lights dont light up then it means that the AC adapter jack on the laptop has bad solder joints and/or damaged. It is located at the underside of the motherboard where the AC adapter is plugged in. You will need to take the laptop apart and re-solder/replace the jack.

Let me know if you need more help,
Sai.

Can the dc power plug be repaired?


If you are referring to the DC Jack..(the port where your AC Adapter Plugs into) then typically No, THey are cheap enough that it is best to replace with new.... Yes they can be repaired, but chances are they won't hold up to the stress, and will just cause problems down the road...

Desolder The Faulty DC Jack... Go Slow, Use Solder Wick/Desoldering Braid... And A Solder Gun...Flip Motherboard to the underside of the DC Jack, You want to put a very small amount of FRESH solder on all Pin ends of the DC Jack - this will allow better flow of the solder when trying to remove...
Then Use The Desoldering Braid and slowly remove the solder from the DC Jack Pin Contact Areas... Do Not Rush or you will ruin the contact pads on the motherboard, you must make sure all solder is removed,,, if you attempt to rip out the jack cause you think its "good enough" you will end up pulling the C ring from the center of the Jack Pin Hole...

Once You Have All Solder Removed Use Some Flux Paste And Again go over each pin to ensure all solder is gone, then you can remove the faulty DC Jack...

Now.. Clean the motherboard where the DC Jack Was... Remove All Old Flux and take your solder gun and go over the Jacks contact pads so that you have fresh solder on all...

Now Add a small amount of flux to all the DC Jack Contact Pads and add alittle to the Pins on the replacement DC Jack.....

Then Solder The New DC Jack Into Place... Solder The BottomSide First... The Pin Ends ..

Then Flip Over and add small amount to the side negative pins and the power pin(s)...

Now you are done..

You can add Some Heat Resistant Automotive Epoxy ( Safe On Electronics) to the sides and back of the new dc jack.... this will double the strength and prevent future damage/wear and tear...

My r3000 has a tempermental power supply. it


whatabout the lead that plugs into the laptop ? does the plug in the laptop move easily, with the lead in, Sounds like the actual plug in the laptop is breaking away, the solder around the connector. Sadly to fix that you will have to get it repaired for about £50 to £70, maybe more ?? please make sure the lead from power supply is not loose or a bad fitting.
