    Didn't replace daughter board but exact same problem. This lady gives me her laptop telling me it hasn't powered on since last year. She never dropped it and the laptop looks like she just took it out of the box. I took the thing apart piece by piece and back together. Tried 2 different ac adapters and it's not the battery or a charge left on the motherboard. Really like the way Acer doesn't provide and service manual either on their website (gee I wonder why?). This is why I would never buy a new laptop. Acer, Compaq, HP...they're all ****. I feel bad for this woman ...goes out a buys a brand new laptop and it stops powering up in less than 2 years. Pretty pathetic Acer. I wouldn't spend more than $400 on a laptop. People go out and pay for the laptop, and then office, and then the anti-virus, and then extra warranty and next thing they know they've spent $900 on a laptop with Vista basic LOL. Glad I'm an IT guy that's for sure.

What! !O_O!

For a statement, such as, "Motherboard not on", you would be stating the motherboard either does not receive power, or the motherboard does not use the received power.

Primer:
You press the Power On button. The first chipset to receive power is the BIOS chipset. The Basic Input/Output System program is initialized.

BIOS looks to see what devices are connected, does a Ram Memory count, turns the Processor (CPU) on; and hands the computer over to the Operating System. (In this case a version of Microsoft Windows)

If the statement is the motherboard is not turning on, you are in effect stating the BIOS chipset is Not receiving power.

Diagnoses must start from the AC adapter (Charger) You need to know if the AC adapter is putting out the correct Voltage. Also while testing have an assistant, gently wiggle the cable FROM AC adapter TO laptop; and power cord TO AC adapter. Any fluctuation in the reading, means a broken wire.

AC adapter proves to be good, the diagnoses goes to the DC Power Jack. The DC Power Jack is the jack on the laptop, that the AC adapter plugs into. (DC_IN)

AC adapter removed, Battery removed; a small instrument is used to see if you can gently move the DC Power Jack. ANY perceptible movement means a bad DC Power Jack -> Replace.

DC Power Jack checks out OK, then the problem will most likely be the Power MOSFET's on the motherboard. They determine if the Battery is to receive a trickle charge, or full charge. Also determines if the laptop is to run off of the Battery, or just the AC adapter.

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

I can give a lot more, than the generic information above, if I had the Model Number of the Acer laptop. This is on the Bottom of the laptop. Post back in a Comment.

Battery won?t charge and AC adaptor not recognized


I have a Dell Inspiron 6000 that just turned two years old.

After one year, my dell 6-cell battery started to falter, so Ipurchased a new 9-cell battery. This worked fine until a couple ofmonths ago when I noticed that my 65W adaptor was frayed. I bought anew 65W Dell Inspiron 6000 ac adapter andit worked well for about a week until I noticed that my battery wasn’tcharging at times. If I was patient, or unplugged the adapter andplugged it back in, the battery began charging and all was saved.

This lasted only a short time until my Dell Inspiron 6000 batterywouldn’t charge at all for long periods of time, and sometimes thecomputer wouldn’t turn on, even if plugged into the wall. I thought itmight still be the adaptor, so I borrowed a fully functioning 90W Delladapter from a family member to test the system. This worked better,but still not great.

When I removed the battery and started only fromAC power, the functionality was also intermittent. Usually, if thecomputer actually started, I received the start-up error “The Inspiron 6000 AC AdapterType could not be determined, etc. etc. etc.” After pressing F1, thecomputer booted, but if the battery wasn’t in, the computer didn’tusually last long before shutting off. Unsure if maybe the battery wasthe problem, I put the 6-cell Inspiron 6000 batteryback in, and it too wouldn’t charge, although (together with the 90Wadapter) my computer would at least start more consistently if pluggedin. The error remained however, and sometimes the system stopsrecognizing power and switches to my ever dwindling battery power untilthe adapter is recognized again.

The problem is with the jack on the motherboard inside our Inspiron 6000’s. This is the jack you plug your power plug into on the back of the laptop.

Somehow the jack gets worn and does not make correct contact withthe laptop so the Laptop does not see the power supply as a legit Dellbrand. So the powersupply will not charge the laptop battery and run the laptop at the same time.

A bad connection between DC-IN power jack on the system board and the system board is a very common problem with dell pa 12,dell e1505 and Dell Inspiron 6000notebooks. If your laptop is out of warranty, then you can fix theproblem by resoldering DC-IN jack on the system board. If it’s stillunder warranty, it would be fixed at no charge to you. Problem symptoms:

  • Laptop randomly shuts down without any warning.
  • Power LED and battery charge LED start flickering when you wigglethe power cord or the AC adapter tip on the back or your laptop.
  • The battery will not get charged.
  • When you plug ac adapter for laptop, the laptop appears to be dead and there is no LED * activity at all (DC-IN jack on the system board is broken).
To fix the problem, you have to take your laptop apart, remove the system board to resoleder or replace the DC-IN jack. dell pa 12 and Dell Inspiron 6000 disassembly guides will help you to remove the system board. Take a closer look at the power jack on the system laptop board witha magnifying glass. In most cases you get the power problem because ofa bad connection between the DC jack and the system board, you’ll see acrack between the DC jack connector and the system board.

My Acer 5630, suddenly cannot turn on. I already replace DC power adapter by a new one, but the problem still exist. Anybody can help me.


If you have already changed the charger, and tried running it without the battery, it sounds like you have a Mother Board failure. You should contact Acer and have it replaced.

Advent N270 netbook will not charge. Orange light comes on initially then goes off. Also when I wiggle the plug into the laptop the light flashes on and intermittently.


It sounds like either a bad connection on the motherboard or a broken wire in the adapter making intermittent connection.

1. With the power adapter disconnected, do you have a power light? This would indicate the adapter is good and the plug is questionable.

2. Check your power adapter output with a multi-meter.(be sure to wiggle the wires around) If the power fluctuates, replace the plug.

3. If the power is solid, replace the motherboard connector.

Laptop won't a hold charge when plugged in


Remove the Laptops Battery, Plug in AC Adapter... Is it able to Stay Powered On?? Slightly wiggle the Cord Near the plug end while plugged in... Does it still receive true power??? If So, Its Not Your AC Adapter Or Your DC Jack And You should Look into Replacing Your Laptops Battery...

If You Are Not Able To Power THe Laptop Using Just The AC Adapter When The Battery Is Removed, Then You First Need To Check/Test The AC Adapter using A Multimeter To See If You Have A Faulty Cord... If Cord Is Still Getting Correct Power Through To The Plug Tip .. Then You Will Need To Replace The DC Jack (the port where your AC Adapter Plug Plugs into on the laptop)

Power cord attachment into the back of computer seems worn, it wants to run off battery instead of recharging through power supply


Either Have A Failing AC Adapter, Or A Failing DC Jack
you can test the AC Adapter using a multimeter (available at any home improvement center for $6)..
The DC Jack Would Need To Physically Be Checked To See If It's Faulty... which would intail removal of all parts down to the motherboard and visually inspect the DC Jack (the port where the Charger Cord Plugs into)



Remove The Battery... Plug AC Adapter Into Laptop.. Attempt To Power On....
