Re: pressario r3000

I have the same problem. I found this blog to be helpful in taking apart a Compaq, also the user manual from Compaq, available here is very complete.

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)

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,

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.

R3000 DC025052300 unplugged

Right after the rj11 jack where you plug your landline in. You can follow the leads easy from the jack. Opposite side of the processor side.

Worn power connection

Well, if it's just the soldering points that are weaking then you don't need a new one. Just resolder those points (probably won't even take any extra solder but i would recommend giving it a little more so it doesn't just break again) and you should be fine. If the actual jack is damaged then you'll have to replace it. No real ease here, though, as you'll have to take the laptop apart either way.

CPU fan operates but laptop otherwise dead ?

Remove the battery and plug in the power adapter. Attempt to power on the laptop. If nothing happens, then try holding the power cord, at the jack, at a different angle. Wiggle it a little and see if the laptop will come on. If it does come on, then wiggle it some more and see if the laptop cuts off.

This will determine if your DC Jack is faulty. I have resoldered a bunch of these on this model. Usually the solder around the HOT pin on the mainboard cracks. Thus, you don't get a good power connection.

Now, as far as the laptop coming on with the battery.... how long will it run on just the battery? A couple seconds? Or a couple minutes? Or until you turn it off? If the battery were about dead, then it would come on for just a couple seconds but not POST. Meaning no video or anything. But if it comes on and runs for several minutes without turning off, then a weak battery isn't the problem. It should still POST and show video and all that.

So, even if you get the DC Jack fixed, assuming its faulty, this may or may not solve your POST problem. Never know really until the dc jack is for sure supplying good steady power.
