SOURCE: Power supply problem

This is going to be with the power management system on the motherboard. These are the classic text book symptoms of a failed power management chip. Few shops will be able to fix this, most just say replace the motherboard, you might get lucky and find one in your area that can fix it, if not then you will need to send it to Acer for repair.

SOURCE: DC power inside computer will not charge battery.

Most likely, the DC jack on your laptop has broken either a solder joint or one of the leads the connect it to the motherboard. Unfortunately, it's a common thing on some laptops due to the stress the DC jack sees during use (getting banged around, yanked out, bumped, etc). If you're lucky, there are instructions online on how to disassemble your particular model of laptop to the point of reaching the DC jack, but you should be very comfortable with such an endeavor (and a soldering iron) before attempting it. Otherwise, a local computer repair shop should be able to help you out.

SOURCE: Dell Inspiron 1505; Battery does not charge; DC jack is loose..

The loose connection for the AC adapter means the motherboard needs to be replaced or the AC adapter jack on the motherboard needs to be replaced. (With Labor, it is about the same cost to buy a new motherboard as it is to have the old one fixed)

Motherboards are available on EBay for around $100

First, you need to make sure your power adapter is providing enough power to both run the laptop & charge the battery. A very good way to do this is to compare your laptop voltage & ampere requirements (written on a sticker on the bottom of the laptop) with the voltage & ampere ratings of the power adapter. Voltages should be the same, or the power adapter's voltage about up to 0.5 volts more than the laptop's voltage rating. Amperage of the power adapter should be at least equal to or greater than the laptop's rating. It should never be less than the laptop's rating, or else the power adapter will be providing insufficient amperes to charge the battery. Of course, the power adapter's nominal amperage might be ok, but it degraded on usage. You can verify this by testing using a good or new power adapter.
If the battery did not charge using the new power adapter, take the battery off the laptop, & using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self, then put the battery back into the laptop & try again.
If this still did not resolve the problem, then the battery itself could be bad. Try it on another laptop, or try a good or new battery in your laptop.
If this did not work, there might be a possibility that the charging circuitry on the laptop's motherboard is defective & needs servicing. In order to do this, the laptop needs to be disassembled & the motherboard checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether.

When I connect the dc plug into the laptop the laptop shutsdown


I have had a similar problem. If the battery is not holding a charge, then something is wrong with the charging circuit inside the battery pack. Remove the battery pack from the computer and reconnect the power supply and see if it stays on. If not you will need to check the voltage for the power supply.

Believe problem to be one of the Power MOSFET's, in the DC - DC circuit on the motherboard

http://en.wikipedia.org/wiki/DC-to-DC_converter

Using the HP Pavilion dv6000 series and Pavilion dv9000 series, of Notebook PC's for an example,

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

The two Power MOSFET's used; are the Fairchild Semiconductor Industries -FDS6679 - Power MOSFET, and the Alpha & Omega Semiconductor LTD - AO4407 - Power MOSFET.

Showing availability and cost. Using just FDS6679 for an example,

http://www.mouser.com/Search/Refine.aspx?Keyword=fds6679

Obsolete. Using cross reference match example,

http://www.mouser.com/ProductDetail/Fairchild-Semiconductor/FDS6679AZ/?qs=sGAEpiMZZMshyDBzk1%2fWi1qxDdW%2fXBi2qgMuZEfLVO4%3d

One dollar and one penny USD.
AO4407 is obsolete too. Cross reference match example for it, cost is 78 cents USD.

NOT stating the P.MOSFET's are used on your Sony VAIO's motherboard. Showing what a Power MOSFET looks like for this type of application, and availability/cost.

Look on your motherboard in the DC - DC converter circuit area, where the DC Power Harness plugs in.

[The AC adapter (Charger), plugs into the DC Power Jack on the laptop. (DC_IN)

For your laptop the DC Power Jack is connected to wires, that end in a male plug connector. The male plug connector plugs into the motherboard.

It is now called a DC Power Harness ]

Let's take a brief look at a motherboard example,

http://www.ebay.co.uk/itm/Sony-Vaio-PCG-6L1M-Laptop-Motherboard-A1171213A-Spares-Repair-NO-POST-/360566230317?pt=UK_Computing_Housings_Touchpads&hash=item53f36c0d2d

(Sony VAIO PCG-6L1M and VAIO VGN-B1VP are supposed to be the same)

The Main view shows up automatically, with the Top view of the motherboard.
Scroll down for Bottom and Top view.

Again there is a Main view, and this time two smaller views to the Right.
Top small view is Top view of motherboard.
Bottom small view is Bottom view of motherboard.

Looking at Bottom view of motherboard, believe DC Power Harness plugs into the Right side.
Series of Power MOSFET's are on the right side, also.

WEAR an ESD wrist strap, and have it's alligator clip attached to a good ground source.
Here is free access to the Service Manual.
You want VGN-B

Errore000064 occured


Power supply voltage error (high-voltage error)

The presence of a high-voltage error is communicated by the composite
power supply PCB. (The output for primary charging, developing, or transfer
has deviated from a specific level of voltage.)

Main cause: The contact has poor connection. The wiring is faulty. The composite power
supply PCB is faulty. The DC controller PCB is faulty.

Action
1. Contact
Is any of the contacts of the primary charging roller, developing assembly,
or transfer charging roller soiled? Or, is there poor contact?
YES: Clean the contact, and set it once again.
2. Wiring
Is the wiring between the contacts for the following normal: DC controller
PCB (J301), composite power supply PCB (J136), primary charging roller,
developing assembly, transfer charging roller?
a. DC controller PCB (J301) <-> composite power supply PCB (J136)
b. composite power supply PCB (J130-7) <-> primary charging roller contact
c. composite power supply PCB (J130-1) <-> developing assembly contact
d. composite power supply PCB (FT133) <-> transfer roller contact
NO: Correct the connection.
3. Composite power supply PCB, DC controller PCB
Try replacing the composite power supply PCB. Is the problem corrected?
YES: Yes.
NO: Replace the DC controller PCB.

Battery does not charge, but remains on with power supply connected. Female to male connection "touchy." Can turn off if cord is barely touched. Main concern being how to fix female part of power supply.


DC Jack diagnosis:
1. Test power adapter for output voltage. Bend the power cable in various directions while doing this to be sure that there is no broken conductors in the cable.
2. If power adapter is Ok, connect it & see if the power LED on the laptop will glow when you jiggle the power connector in various directions. If yes, then the DC jack might be loose or damaged, & need to be either re-soldered or replaced.
3. If not, then disassemble the laptop. Remove any components that attach to the laptop's motherboard first (e.g. battery, hard drive, RAM, wireless card, optical drive, ... etc.)
4. Next, remove the keyboard & the LCD screen.
5. Finally, unscrew all screws that hold the upper cover & lower cover together so that you could gain access to the motherboard.
6. Inspect the solder points connecting the DC jack to the motherboard. Make sure that none of them is loose. If any, re-solder them.
7. Inspect the center pin in the DC jack. Make sure that it is not broken or loose. If it is, then you might need to replace the DC jack.
8. When you are done, re-assemble back the laptop.

HP Compaq laptop won't charge/power from AC due to blown fuse


Hi there,

There's plenty of causes why your laptop would not power up from the AC adapter and won't charge the battery. Here are some possible causes and solutions to this problem:

Number one, if it's on battery power, the battery is dead or the battery is bad and number two the AC adapter could be bad. Let's roll out number one.

1. Take out the battery, remove main supply, hold power button down for 30 seconds. This will drain the charges in your

battery. Put only power supply in, do not put battery in, turn laptop on, put the battery in.

2. If the solution in no.1 doesn't solve the problem, pull the battery out, keep the battery out of the laptop for this test.

Take your AC adapter and check the voltage with a voltmeter. What you want to test for is voltage. Put the meter at 20

volts DC and take the tip, the power jack tip of your AC power adapter. You hold the black, (the negative part) of your

voltmeter on the outside of the power jack tip of your AC adapter and you put the red (the positive part) of your voltmeter

in the hole in the inside of the power jack tip of your AC adapter. Be very careful not to touch the red and the black part of

your multimeter and the power jack tips of your AC adapter together, otherwise it will create a short circuit.

After doing these procedures, if your AC adapter is good it will output a voltage which ranges from 18 to 19V DC on your

voltmeter, depending on the voltage that puts out on your AC power adapter. If your voltmeter doesn't show any voltage,

probably your AC power adapter is bad or damaged. But if your voltmeter shows up voltage, then we have to go to the

next possible cause why your laptop won't power on.

3. The dc jack on your laptop might be bad, if the dc jack on your laptop is bad or not making a connection to the

motherboard then it look the battery is bad as well, because the battery is now not holding a charge or even taking a

charge. Also, even if your AC power adapter is good and when you insert it to the dc jack in your laptop it could not power

up the laptop because the dc jack is not making a connection to your laptop motherboard in other words the dc jack might

got loose, that's why it's not making any connection to the motherboard. The only way to solve this is that you have to

disassemble your laptop, and take the laptop motherboard out and look where the dc jack is connected. After you found it,
take a file tool and file off a spot on the motherboard where you can reattach the power jack and use a wire to reattach

the power jack to the motherboard.

Hope you find this answer helpful. God bless.

It is possible that it could be a bad solder joint. It could also be that the connector is a different one. Some laptops use a dual voltage power structure. On the Inspiron E1505 (same as the 6400) I have it requires the dual voltage power. This is where the outside of the plug is the ground and the inside of the plug is one voltage and the center pin is yet another voltage. In this case, (if I remember correctly) the inside of the plug is like 19.5 volts and the center pin is like 9 volts. The inside of the plug supplies the power to the laptop and charging circuit and the center pin tells the laptop that the power adapter is plugged in and should start charging. If the laptop recognizes the Vostro power supply then this is a good possibility. Either way, it is worth getting it checked out. The last thing you want to do is burn out the charge circuit on the motherboard by having the incorrect power supply plugged in to it. It may work for a while or it may work forever but you never know.

1. Connector
Is the connector of the fixing motor connected?
NO: Connect the connector.
2. Main power supply PCB
Is the drive voltage (24 V) of the fixing motor supplied by the main power
supply PCB?
Main power supply PCB: between J202-3 (24VU1-S) and J202-4 (OVU1)
NO: Replace the main power supply PCB.
3. Fixing motor (M19), DC controller PCB
Press the Start key. Is the lock signal of the fixing motor present at the connector
(J312) on the DC controller PCB?
Lock signal: J312-B4 (FSRM_LOCK*)
the DC controller PCB change from 0 to about 5 V?
YES: Replace the fixing motor.
NO: Replace the DC controller PCB.


BUT FIRST: did you removed fixing assy from any reason? If you did try to repositioned it. Check for any foreighn matters inside or around the fixing assy. Try to reconect the fixing assy connectors. Check gears of fixing assy and drive assy.
