Loose power connection on motherboard of Satellite L640D-ST2N01


Toshiba Satellite laptops often have problems with their power connections becoming loose and losing contact between the positive pin on the DC power jack and the motherboard. Laptops are not designed to operate on the battery when the AC adapter is plugged into a viable power outlet. You will have to disassemble your Toshiba Satellite laptop to repair this problem. This task requires a thorough knowledge of laptop repair and safe soldering practices.

1. Disassemble your laptop according to the instructions for your specific Toshiba Satellite laptop model. Cut the plastic supports off the base assembly with a knife.

2. Cut off the plastic wall that encircles the mount opening with the knife. Extend the circumference of the hole by carving it open with the knife to make it wide enough for the new jack.

3. Bring the ends on the negative lead for the jack together and cover the ends with solder.

4. Remove the original DC power jack and trim the wires from the jack box with the knife, until they sit close to the edge of the jack box. Use the knife to strip the wires. Use your fingers to twist the wires together, and then coat the point where they meet with fresh solder. Locate the positive wire -- it is either red or green. Plug this wire into the positive lead on the new jack, and then find the negative black wire and attach it to the negative lead on the new jack.

5. Place the new power jack in the base, keeping enough extra space available for the plastic laptop cover and right speaker to fit back in later. Cover the negative and positive leads with the electrical tape, and then manually rotate the nut on the power jack clockwise until it will go no further.

6. Figure out which walls will stand in the way of the power jack after you secure the plastic laptop cover. Cut these walls out with the knife. Reverse the disassembling instructions you followed previously to put your laptop back together.

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.

The left hinge on my MX6436 gateway laptop is cracked. How can I fix it?It is split from the screw in the back out to one side and making it difficult to open and close.


If you have to ask "HOW" to disassemble your laptop, in order to remove and replace the hinge, then STOP, and take the computer to a qualified technician, who can safely make the repair.
