Power button The Ac plugin in the back of my laptop came loose and the negative wire came loose. So I fixed that problem, but afterwards, I run into another. When I press the power button to turn it on, nothing happens. The battery is fully charged the ac power cord is working. I'm not too sure what to do here.

if you are pointing about the loose dc power jack adapter, i suggest you have to take it to the shop for repair. it's either you have a faulty adapter, or one or two pin doesn't have contact. usually negative contacts looses if your power button lights ups, but the MOBO doesn't get the right voltage that's why it doesn't boots up.

thanks

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.

The power plug in port you refer to is the DC Power Jack.

The AC adapter (Charger) converts AC electricity into DC electricity.
DC electricity has two poles. Positive, and Negative.
(Just like on a D cell flashlight battery)

The center pin of the DC Power Jack is the Positive connection.
The outer metal spring-like pieces, on the inside of the cylindrical shape surrounding the center pin, are the Negative connection.
(The pieces of spring-like metal, all connect to the Negative connection in the DC Power Jack)

Cannot agree with the replacement instructions they offer, at the bottom of the page.
Not everyone has access to a hot-air gun. A 25 Watt soldering iron, and Desoldering Braid, is better, and more easily accessed ]

1) Remove ALL power. Remove the AC adapter, (Charger), and Battery.
2) Observe Anti-Static Precautions. Buy, and use an ESD wrist strap.
Electro Static Discharge.

(Average cost is from $3 to $6. Connect the alligator clip to a good ground source.

Hi. Try theses simple steps:

Remove the Battery
Remove the AC Adapter
Press/hold down power button for 10 seconds
Plug AC Adapter in and turn the computer on
If the system doesn't turn on still then there's a problem with your motherboard. and it might need replacement.

Hi. I would suggest that you powerdrain your computer might fix this. To powerdrain your computer you must remove first the battery and unplug the ac adapter then press and hold the power button for 20 seconds, after that you must place back the battery and plugin the ac adapter then turn on your computer. If this doesnt work try to powerdrain again the laptop then just use the ac adapter to turn on your computer and that is without the battery. Hope this helps.

probably have a loose wire. i'd suggest removing the battery, taking the back cover off and look for a loose wire. however, if your still in warranty send it for repair.

If this doesnt fix the issue, you might consider reformatting your laptop or restore it using the recovery cd. Hope this helps

1. Remove laptop battery, optical drive, hard drive and ram. Remove external peripherals as well.

2. Make sure AC Adapter is not yet connected to the laptop. Pressand hold on the laptop’s power button for 10 seconds to drain the powerflea.

3. Connect the AC Adapter for laptop to a known good power outlet, check ACAdapter power LED if it is on. Try to sense if AC Adapter is not makinga bit of noise when it is plugin to the wall power outlet.

4. Connect now the AC Adapter tothe laptop. Check if AC Adapter LED stays on when it is connected tothe laptop. If the LED stays on means the AC Adapter is fine. If the ACAdapter LED turned off check the AC Adapter pin that goes to the laptopAC socket if it is loose.

5. If AC Adapter stays on after connecting to the laptop try topower on laptop. If no power LED comes on then this is motherboardproblem.

6. Before replacing the motherboard there is one checking needs todo. If you can open your laptop bottom part then good, do this whenlaptop is not connected to any power source. Try to reseat the laptopCMOS battery then try to power on laptop after, if still fails thenreplace motherboard. I hope this helps.

Hello

It sounds like your AC cord or the female plugin soldered onto the motherboard has gone bad and will no longer make a connection to charge the battery or power the laptop on.

You would have to try a new power cord to find out which is the problem. If the cord fixes it, then it was just a bad cord (as you said it gets very hot, this maybe a sign of a cheap cord that has gone defective).

If the cord is not to blame, then the female plugin is loose and there is little you can do unless your an expert at soldering.

Post back with anymore questions or comments for additional help. Thank you for choosing Fixya!

the most likely reason is a systemboard problem (the ac plugin port cannot changed independently for notebooks)
