My sony laptop heats to a vey hot temperature and seems bad. Is it just the laptop or is it a problem? 2nd, my ac adapter is loose when connected to the laptop and stops receiving power unless it is connected in a specific way.Some plastic in the socket is broken off.The ac adapter gets very hot(only where the laptop and ac adapter meet). My last problem is speed. my laptop slows down and it has plenty of room in the hard drive.

Re: overheating and ac adapter disconnection
O.k. Let's start by addressing the DC jack on the laptop. This needs replaced immediately, ASAP, do not pass go, (got the picture). With the jack being broken there is the very good possibility of creating an electrical arch which can do major damage to the machine. An arch can fry the motherboard and everything attached, hard drive, memory, wireless card, keyboard, and CD/DVD drive, leaving you a door stop with a good screen. Stop using it immediately until you get the jack fixed. Once you have the jack fixed I believe that your other problems will be cured also. The laptop overheating and running slow is from the machine starving for power and the hot power supply is from the backfeed at the broken jack.

1) Is it the Samsung AC adapter the laptop came with? I ask because a generic aftermarket unit may cause this.
The laptop requires 19 Volts DC. I have seen 60 Watt versions, and 90 Watt versions. You do NOT want the 60 Watt version.
To low a power will cause the AC adapter to overheat, and/or the laptop.
If it's a replacement it should state; Output: 19VDC @4.74A ~ 90W
(Input: 100 ~ 240VAC 50~60Hz)
2) Laptop is not on a hard flat surface when being used. This causes blockage of the laptop's cooling system, and the laptop to overheat.
Heat = Wasted Energy The AC adapter strains to keep up with the needed call for power, and overheats.
3) There is a part loose inside the laptop. Causing a short circuit. May be a foreign object, and not part of the laptop at all.
This would mean wearing an ESD wrist strap, with it's alligator clip attached to a good Ground source; and disassembling the laptop to find out.
(Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer. An ESD wrist strap relieves your body of Static, and keeps your laptop safe; when repairing. Average cost is $3 to $6)

It would appear that there is a motherboard issue with this model laptop from Dell. Below is a link to the discussion thread for the problem you described. Unfortunately, there is no current solution for this issue - short of replacing the laptop.
So the DC jack on the motherboard is Heating Up? I'm assuming the AC Adapter (charger cord) is also HOT...??
Here's what your issue is:
1. You're using the wrong volt/amp Adapter..(charger) For Example.. Your Laptop needs a 19.5v Adapter and you are using an 18.5v
2. You're using a "generic" AC Adapter and Not an OEM one.. the generic adapters will overheat and sometimes even melt due to Cheap capacitors/resistors being used..
3. You need to clean your Fan/Heatsink.. Clean the heatsink cooling fins to free blockage and stop overheating issue..
Or .... 4. Possible faulty battery
The power adapter does not have a temperature sensitive device, therefore it won't stop for overheating if not in consequence of a fault.
Try leaving the power adapter unplugged for about ten minutes. In the meanwhile also remove laptop battery and put it back. Connect it back to AC and laptop. Ensure that connection to laptop and power cord connection to AC adapter box are both well plugged. Before turning on laptop leave it connected for few minutes. If laptop still does not turn on and battery does not charge, then the AC adapter is faulty. A further test can be done using a multimeter to read voltage on AC adapter plug.
A replacement AC adapter is not expensive and can be purchased online. Try entering in Google your Toshiba model followed by the words "power adapter".
You either have a faulty ac adapter; a bad power supply in your laptop; a bad battery; or a blown LED indicator light.
1. If the connection is not loose when you plug in your ac adapter try letting the laptop charge for a while. (If you are using the correct ac adapter)
2. Try removing your battery and using the ac adapter. If this works the battery is bad.
3. Try a new ac adapter.
4. Power supply is bad
It could be a fault with your laptop which is drawing more current than what the AC adapters can supply.
The adapters are under too powered for your laptop.
Check the voltage and current rating requirements of your laptop, this information is printed on a label on the bottom of the laptop.
The adapter should have the same voltage and current rating or same voltage with a higher current rating.
Often, if a system turns off every time at roughly the same time, it's a hardware problem. System gets too hot, shuts down, restart it and it'll run again for a while, but not quite as long, and continue like that. Can you feel/hear the fan moving air? Possibly clogged, see what you can do to get it cleaned up a bit. Does it make any difference what surface it's on? May be covering a vent on the bottom or back.
