Question about Sony VAIO VGN-FE870E/H Notebook

1 Answer

Charger pin which you connect to laptop socket gets heated.

The charger PIN where you insert into the socket of the laptop gets heated heavily.  I have a Sony vaio laptop. I thought that the charger is the problem then bought another charger with same specifications and tried but still the problem is the same. The pin gets heated and feels like it will melt.

Any solutions..

You will need to take this in to a BackStage center at any Sony Style store to have it looked at for defectives.

My tablet wont charge when put into mains charger this is the second time my charger connection feels lose

which end feels loose, the dc socket on the tablet or the mains (240volts) end (three pin plug?).

If the mains end, you need you need to get a new charger, it is dangerous to continue using it.

If it is the dc socket end, there is not a lot you can do about it, as it is solder to the mainboard, unless you can unsolder it and insert a new one.
Have you thought about gluing the dc side into place, so it cannot move?

How to concert laptop to tv

what do you mean by concert, Do you mean connect?
If you do then you will need a 15 pin to 15 pin vga lead. Connect it to the 15 pin socket on the laptop, connect the other end to the tv's 15 pin socket if it has one. Then select PC on the tv's input source menu using the tv remote. Switch on the laptop and it should display on the tv.

Dell laptop latitude C640 model pp01L will not charge or boot

1) Check the AC adapter (Charger) to see if it is putting out 20 Volts DC.

Use a multimeter with the Function knob set to DC Voltage. If just a symbol, the symbol is a dotted line over a solid line.

If there is a multiple setting for the Function knob with DC Voltage, set it to the 0 to 50 Volt (DC) scale.

If you do not have one, or access to one, an economical yet reliable multimeter, can be purchased for as little as $10. (Less in some places)
A multitude of stores carry them. An auto parts store is but one example.
Analog or digital doesn't matter.

This is the DC Power Jack. May be labeled as DC IN on the laptop,

I want to show you it, and have you look at the cable end, that is coming from the AC adapter (Charger) TO the laptop.
(To the DC Power Jack)

See the 3 pins? Arranged in a triangle? Note the socket holes in the cable end.
The pin that sits all by itself on Top, is the Positive pin.
The two pins down below are Negative, or Ground, pins.

The Positive (Red) probe lead of the multimeter, is inserted into the single socket hole, in the cable end.
The Negative (Black) probe lead can go into any of the two bottom socket holes.

Read very near 20 Volts?
Have an assistant wiggle both cables. First the one from the charger To the laptop, then the one from the charger to the wall receptacle. (Or surge protector, actually)

2) Charger checks out?
Go to the DC Power Jack.

You may wish to skip checking the charger out first, and check the DC Power Jack, if you Know that the charger is good.

Battery removed see if you can wiggle one of those 3 pins around.
Be gentle, use a pencil if available.
ANY perceptible movement means a Problem.

Looking back at the second link above showing the DC Power Jack, note the metal prongs coming down towards the bottom of the jack.
There are 4.
2 on each side.

Note the 3 long pins sticking down towards the back of the jack.

The 4 outside prongs made from the outer case, are used to anchor the jack into place. They go down through holes in the motherboard, and are soldered on the opposite side.

There may be Ground attached to the case through these prongs also.

The two pins sticking down towards the Back of the jack, are also Ground pins. (Negative)
The single pin by itself is Positive.

A) IF, any of the pins wiggle, the jack is broken, and needs to be replaced.

B) IF, the outer shell of the jack wiggles, the jack May just need to be soldered back into place.

(Could also be an indication of more damage than appears to the eye)

Same thing for the single Positive pin solder joint.

Charger checks out, DC Power Jack checks out, the problem may be a bad power sensor chipset.

This chipset senses when the laptop battery needs a full charge, or a trickle charge, or no charge.

This means it also will sense when the laptop is to be run straight off of the charger, and not the battery.

Usually means motherboard replacement, unless you have access to the chip, and means to replace it. (Soldering tools, and technique)

Appreciate it if you would keep me apprised as to what you find.

Hello,i have a problem with my laptop.. i put to charge and nothing !I should take new baterry? pls help. model -emachines nav 51

Hi ,
First of all please confirm that your charger is working.
Then check your battery weather it is dead or not.
If your battery is ok ,then there must be charging socket problem and charger-connecting pin with motherboard.

When you put the charger they have light and no power

Please remove and clean the Battery terminals of the Notebook, make sure that the output pin of the AC Adapter is properly connected to the notebook. The fault might be either with the output pin of the AC Adapter or Input DC socket of the Notebook.

The audio socket on my Nokia 6613 cell phone is broken inside the phone where the pin end of the charger plugs in. How can i repair this?

Its simple, provided you have a phone screw driver and you know a store where you can buy the audio broken socket and the pin end of your charger.

Turn off the phone, remove the battery, loose all the phone screws and carefully remove the phone cover. Locate the broken parts and buy a new one and do the replacement.

If I am not mistaken, what you are referring to as "pin end of charger" is called charging port.

If you can't get any of the above fixed, then I would advice you give it to an an expert to do for you. But try is yourself, its very simple but you just need to be careful. You can start learning for there.

I wish you the best.

My acer aspire 5315 doesnt charge properly.

I'm sorry to say that your initial fears are correct and the pin that the adapter connects to in the laptop is loose. This is a common problem with laptop's and can be easily dealt with.
Now I'm not going to tell you to open the laptop up and de-solder the adapter (unless you want me to).
Because this is a fiddly job and you have to order the correct adapter i recommend you take it to a reputable repair store and have them replace the adapter for you, don't let them tell you that you need a new motherboard as this is not the case at all, adapters can and do get regularly get fixed and is not that expensive.

Good luck.
