DC power input center pin is gone

It sounds like your backlight is damaged. On some units this can be replaced on its own. On others, it requires the entire LCD to be replaced. I'll see if I can find out which this is, in your case, and find you a part number.

What is the center pin??

Would you by chance be talking about the DC Power Jack where the Power Cord plugs into the laptop? If so, then see the steps below if your laptop is not booting and you think the DC Jack is your problem.

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

I suggest check out the AC adapter first.

1) When plugged into power, and plugged into the laptop, gently wiggle the cable from the AC adapter TO laptop.

Any change?

Do the same on the power cord TO AC adapter.

NO?
Go on.

2) The port on the laptop that the plug from the AC adapter plugs into, is the DC Power Jack.
If we are discussing an Acer Aspire 5738Z Notebook PC, the DC Power Jack resembles this one, (Not installed),

(When I note the DC Power Jack, it is this link I will be referring to )

As you can see there is a Center Pin. All power removed from the laptop, use a small wooden, or plastic object, and see if this pin moves around.

ANY perceptible movement means a bad DC Power Jack.

DC Power Jack checks out it's back to the AC adapter.
Wanted to perform the easy diagnosis first.

This will require a multimeter. An economical, yet fine for this test multimeter, can be purchased for as little as $8 to $12.

Available in a multitude of stores. An auto parts store is but one example.
Analog or digital is fine.

(Analog is fine. Some of us still like 'em)

DC Voltage is what you are going to check.

Black probe lead (Negative) goes in the Common port on the multimeter. (COM)
Red probe lead (Positive) goes in the Voltage port on the multimeter. (V)

If the multimeter just has symbols around the Function Knob, set it to the dotted line over a solid line, symbol.

The plug on the end of the AC adapter, that plugs into the laptop, has a center hole, and a cylindrical metal shield surrounding it.

The Center Hole of the plug is where the red Positive lead, of the multimeter goes.

The outside cylindrical metal shell is where the black Negative lead of the multimeter goes.

Hold the AC adapter plug in one hand, and at the same time hold the red Positive multimeter probe in the center hole.

With the other hand touch the black Negative lead of the multimeter, to the cylindrical metal shield on the outside of the plug.

You should read 19 Volts (DC), or VERY close to it,

I believe the AC adapter is the problem. Post back in a Comment as to your findings.

these wires do not have a plug they have small gold pins on the end

KiMar, The inverter board (changes DC to AC to keep the backlight on) in your Acer is going bad. It needs to be replaced.

go to this link below and download the drivers need for your aspire notebook 3610.

Good Luck, Kindly POST back with your results.

First thin you have to remember is if you want to have to memories in parallel...Then the new one should be of the same size and frequency(ex:133Mhz,533Mhz..etc.,)Then folow these steps:

1. Turn off the computer and remove all power cords from the computer system.
2. Locate the panel used for access to the memory modules. This is generally located on the bottom of the laptop computer. Refer to your laptop instruction manuals for locating the panel.
   
3. Remove any screws that the panel in place and place somewhere safe to prevent losing it.
   
4. Remove the panel from the laptop and set aside.
   
5. If replacing or upgrading an existing memory module, remove the memory modules by undoing and module clamps and gently lifting the edge of the module to a 45-degree angle and then pulling the module out of the slot.
   
   
6. Align the notch of the memory module with that of the memory slot and gently insert the module into the slot at a 45-degree angle.
   
7. Once all the pins are in the slot, gently rotate the module down flat until the clamps lock into the module into place.
   
8. Replace the memory access panel onto the laptop computer.
   
9. Replace any screws or fasteners that hold the panel in place.
   
10. Replace the power cord and power up your computer system.
