Question about HP Pavilion ze5185 Notebook

2 Answers

Power problem I seems as though the power pin on the motherboard on my ze5185 is 'broken'. We can't get AC power at all...only battery power. Is this something that can be fixed or should we just replace the motherboard? Is replacing a motherboard as easy as just taking out the old one and putting in a new one?

    The power port looks like it's been smashed? What is the part number for a new motherboard?

Suggestions;

Anti-Static wrist strap connected to ground source, and your wrist;

1) The jack your AC adapter plugs into on the motherboard, is the DC Power Jack.
Motherboard out of case, power to motherboard, take your multimeter and see if you are getting 19 VDC at the DC Power Jack's positive solder joint, on motherboard.

The center pin of the jack is Positive. (The inner cylindrical shell is Negative)
Follow the DC Power Jack's positive pin from the Center of the jack, to the motherboard.

You probably won't be able to touch your meter's Positive (Red) probe, to the DC Power Jack's positive pin under the jack; so touch it's solder joint on the opposite side of the motherboard.
(DC Power Jack should be soldered close to the motherboard, is why)

Of course also touch the Negative lead, (Black probe), of your meter, to the Negative, (Ground) solder joint for the DC Power Jack.

Getting 19 volts DC?

See if there is a cracked solder joint, for any of the DC Power Jack's pin connections to the motherboard.
ANY perceptible movement of the DC Power Jack on the motherboard, indicates a bad power jack, and may indicate a broken/cracked solder joint.
Center pin of DC Power Jack is loose? Bad DC Power Jack. Replace.

2) DC Power Jack is determined to be in good repair? No cracked/broken solder joints?
The next components in the power circuit on the motherboard, leading From the power jack, are P. MOSFET's.
Power MOSFET.

Check the links given.

3) The last thing that concerns me, although I probably should have listed it first; is the AC adapter you are using.
Concern is that it doesn't have the 'intelligent chipset' that matches the Compaq CQ1-1225 All-In-One desktop PC's circuitry.

HP Pavillion dv6700 - won't power up


Hi have you tried to power up without battery?

1 Answer

Laptop won't power on with ac adapter or battery


Could be a combination of things.

1) Battery is low. Not enough power to turn the laptop on.
Caused by;

2) AC adapter has a plug on the end of the cable. The plug plugs into a DC Power Jack on the laptop.

The DC Power Jack is bad.

2a) The DC Power Jack has a bad connection to the motherboard, (Cracked solder joints), and/or the jack itself is bad.

2b) Center Pin is loose in the jack's mount.
The back of the Center Pin where it mounts has become loose.

2c) The plastic body of the jack, which composes the jack's case, is cracked. This allows movement of the Center Pin.

2b, and 2c cause a bad connection with the AC adapter plug.

No charge to the Battery, no power to the laptop.

http://www.laptopjacks.com/view_part/For-Gateway-MX6920-DC-Power-Jack-GW51425.html

[ If this is the case the DC Power Jack needs to be resoldered to the motherboard. The cracked solder joints need to be re-melted, (Reflowed)
Entire laptop needs to be disassembled down to the bare motherboard in your hand.
(No Processor, Ram Memory, or any adapter cards mounted to the motherboard. Nada)

OR,
The DC Power jack needs to be replaced.
This entails disassembling the entire laptop, down to just the motherboard in your hand. (Same as above)

The old DC Power Jack is de-soldered, and a new one soldered in place.

Very FEW computer repair shops have the necessary skill level.
They just want to replace the entire motherboard.
IF one is available.
More Ka-Ching for them also. ]

3) The AC adapter is bad.
Not providing power to the laptop, to charge the Battery, nor give power to the laptop without the Battery.

AC adapter cord from adapter to plug, which plugs into the laptop, (DC Power Jack), may have a break in it.

May be an intermittent contact provided by wiggling the cord.
If this is the case the wires have stretched, and broken.
Wiggling causes the wires to briefly touch, and make contact.

Where this cord meets the plug itself. A lot of times there is a break in the wires in this area.

Solution is to replace the AC adapter. There are universal AC adapters you can buy, or perhaps Gateway still has some for sale.

I am getting an error msg Invalid AC adapter on my Dell Inspiration 1525 laptop. For Bootup. The ac adapter indicator light is on. The battery does not seem to be charging it is at 82 %. And seem to be...


If the system is not identifying the AC adapter, then the battery charger circuit is disabled. So replacing the battery will not resolve the issue. If the sensing pin in the center of the power connection to the portable is bent or broken, then replace the adapter. Also try a known good Dell Branded AC adapter, if issue still occurs, it will require an motherboard.

It wont power up


make sure you plug the battery properly or it has ha charge, just to try or check if its in the battery, first remove your battery and plug your ac power cord into your laptop and try to open it, if i work, your battery might be drained or don't have a charge, or you have to replace your battery.

The input jack to recharge my battery has bad connection


YES. This seems to be a common problem. I am just researching doing this with my Gateway.
Things to remember.
1) Shops which do this have the parts to do it right.
2) You might get a better price if you remove the motherboard and just send the mother board for soldering.
3) AND THIS IS VITAL. Some jacks are soldered in such that power is delivered to both sides of the motherboard using a copper sleeve. If you try this at home, you might not get the connection right.
Sorry for the bad news - talk to a shop which can do the repair. I saw prices of $90-$130 for everything except the shipping of course. . .

Wont power up, power cord good. once plugged into laptop power cord stops working


As long as you are abslolutely sure the power cord is functional, without a more indepth analysis, it seems/sounds like the AC connection to the board is broken.

To rule out this conclusion as the failure point, see if you can borrow/buy or better yet, recharge your battery {assuming it has no charge left at this point}

Stick the charged battery into your rig and if it works, yes. The AC connection is broken - nothing a little bit of soldering won't fix.
If it works, will need to ask more 'protocol questions to narrow down the situation'.

...when you reflect on the usage of the laptop, is there a bit of manhandling when connecting the power cord? Do you run it mainly plugged into AC? Dell is infamous for dodgy AC connections strongly lending credence to a broken AC connection to the mobo.

Gateway lap top is not getting any power, the power light is off any solutions?


1. First of all, go to http://is.gd/scG3/gateway/support and enter your serial number to make sure you still have warranty (just in case you need to order parts or send in your lappy) 2. You can open a chat window with gateway to describe to them your issue 3. Possibly order a new part, or fix the solution via gateway support.
ps. My suggestion is either a bad power cable, or bad battery. They will probably send you a new one of either for free if you still have time left on your warranty. Otherwise you'll have to pay, but it'll fix the issue. If you have any further questions, reply to turner.micah@gmail.com.

The computer does not seem to be charging up


Hi,
I am a Dell Certified System Engineer(DCSE)

try taking out tthe battery and then try powering the system only on ac adapter connected
if it doesn't power on only on the ac adapter make sure that the port on the system where you plug in the ac adapter for any kind of bent or broken pins
if the port is ok then get your ac adapter replaced.
