Question about Acer TravelMate 2480 Notebook

The pin that the power cord goes into has broken off

I currently have the power cord set in place by some strong rubber bands going around the underneath of the screen around to the side where the power plug goes in and fits over the male pin that has come off, to keep the connection going. I would like to have it fixed but not sure exactly what needs to be done. I have seen two different pieces to replace that part with, one is just the housing of the pin w/the pin attached and another is the housing with parts of a mother board.
Thanks for your assistance.

Is the cord broken in the computer, or the monitor or the pin broken and stuck in the machine? If it is in a desktop it goes into the power supply. Which you can change the whole power supply fairly cheap. that is if it in a desk top computer. 4 screws, 4 or 5 connectors and ta da new power supply, All you need is readings off power supply such as wattage. Good luck

How to make your Notebook last longer


I have been repairing laptops ,PCs and car amplifiers for over 20years .I own Kips computer service and KIPS CUSTOM AUDIO .THIS TIP IS ABOUT HOW TO MAKE YOUR LAPTOP LAST LONGER.THE THREE MAIN THINGS THAT i SEE BROKEN ON LAPTOPS WHEN PEOPLE BRING THEM IN FOR REPAIR ARE.
#1 THE DC JACK THAT CONNECTS THE NOTEBOOK TO THE DC ADAPTER.These are usually broken from the user wrapping the cord around
the notebook when moving it from place to place.
They also get broken from being tripped on while the laptop sets on a table being used and someone walking by trips on the power cord.(If this problem Isnt Fixed it will eventual ruin the motherboard.
#2- The harddrives in laptops are very fragile moving the LT around from place to place while it is on will ruin the hard drive.

The adapter light is on when first plugged in but then when I connect the adapter to my laptop the light goes off and it doesnt supply any power


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),

http://www.batterysupport.com/acer-aspire-5738-jack-p-302046.html

(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.

http://www.youtube.com/watch?v=bF3OyQ3HwfU

(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.

Satellite P35-S611 has trouble charging


If you have to wiggle the power cord it is most likely the DC jack on the motherboard. It is usually the center pin in the the jack that breaks the solder point and the small tension band inside the jack housing weakens.

The pin in the middle of the power cord input has come out


unfortunately that is an impossible fix...
the only real way to do is complete replacement of internal charging device, which, depending on the laptop, may be cheaper just to go get a new one

Laptop Not Getting Power


There could be a number of resons for this. Some thoughts:
1) Was your laptop working fine before you bought this new adapter? Eg. did it work with the previous one.
2) Are you positive that it is compatible? You should check all the power ratings against the old adapter (voltage output, current output).
3) Make sure the connector that plugs into the back of the laptop is a perfect fit. Connectors have a + and -. The outside metal ring may fit, but the inside 'pin' may be too small and not making contact with the receving part of the laptop.
4) Make sure that the connector inside the laptop has not broken. Easy way is to get a pencil with eraser and stick it in there and wiggle it around. If it moves sustantially, you may have some connector pins that have become unsoldered. If so, you need to get this fixed.

Acer Laptop - key topped popped off


Yes it does snap back on. Place it where it on top of the retainer and press down gently until it snaps into place. You may need to work it around a bit in order to line it up. If it doesn't snap on or doesn't stay, check the bottom of the key to make sure the sides where the retainer goes into hasn't collapsed, or check the retainer to see if one of the pins that snaps into the key isn't bent or broken. If the sides are collapsed or a pin is bent, you can bend the side or pin back into place with a small screwdriver, be gentle as not to break it. If it's broken it will need to be replaced.
