Question about Computers & Internet

1 Answer

My problem involves a Samsung s3520 laptop. Initially the charger socket was becoming very hot when charging. I thought that this was due to a fault with the charger so replaced it. However the same problem was present with the new charger. The laptop has now run out of battery and will not charge at all. It has burst into life a couple of times for a few minutes but no reliable or sustainable charge is present. Any ideas?

Hi.

You will need to determine whether the problem is the battery or the socket on the motherboard.

Remove the battery and try to boot it up on AC power only. If the laptop boots up and stays on as normal then the battery is the problem.

If the laptop won't switch on wiggle the wire while pressing the on/off button, see if there are any signs of life. If it tries to switch on then you have to have the adapter on the laptop motherboard looked at.


Regards.

    Thanks a lot for the reply. It seems to be the socket that is the problem then. The laptop won't run off the mains without the battery in but there are the faintest signs of life when I play about with the wire. Hope it won't be too expensive to sort out.

    The DC socket is fairly inexpensive, the cost will come with the labour involved with fitting the new socket, I suggest you shop around for the best deal.

SOURCE: my acer aspire 5315 doesnt charge properly.

Hi,
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.

A circuit diagram for samsung np-s3520 laptop motherboard


First, check the output of the laptop's power supply with a multimeter. If it is producing the voltage indicated on the power supply's label, your power jack on the motherboard has possibly been physically broken inside the case some how. Another possibility is the battery itself has become defective.

You will need expert desoldering skills to be able to install a new jack, not to mention skills to entirely remove the motherboard from the laptop's case and reassemble it to its original state again. Motherboards are multi-layered and excessive heating of the board can damage "through holes" that must be cleared and cleaned out enough to insert the new part without damaging the board. Temperature controlled soldering equipment is recommended. If the board has become broken, the laptop is likely uneconomical to fix.

Here is a link to someone selling this part on Ebay @ $4.00 USD+ a few dollars shipping if you're located inside the U.S.

Ensure the pattern of the legs of the replacement is the same as the original. This should be obvious from comparing the pattern on the backside of the motherboard where the original jack is located.

My samsung laptop charger gets hot and starts to melt when pluged in and powered up and does the same if i take the battery out please helptried a new battery and new charger could it be the jack on the...


I'm unclear however
Does the new charger get too hot? If so the problem is not the charger or the socket.
Does the laptop work with the new charger plugged in but no battery? If so the socket on the laptop is probably ok
Is the actual charger melting or is it just the plug that goes in the laptop that's getting hot, if it is the plug on both chargers then the socket will need repairing or resoldering, they are a weak point, the soldered pins go high resistance and can generate a lot of heat around the plug and socket. Its usually obvious if the socket is faulty because as you move the plug it makes contact intermittently.
DONT USE THE CHARGER THAT'S MELTING and if both are getting hot have the socket repaired.
If only the one charger getting hot the short is probably in the plug on that charger but read on
On a different note the genuine chargers should be over current protected and overheat protected, they should never melt.

NO POWER


Hello, use the charger on another laptop and use another charge with your laptop. By so doing, you would now if its a charge fault or not. If its not a charger fault, it means the charging socket or the power board of the laptop is defective. You need to disassemble the laptop to get to the root of the problem. Regards.

My samsung gt 15500 won't charge up. It was working fine 2 days ago and yesterday i brought the usb lead to work with me to charge it with my computer. Nothing happened when i plugged it in so i...


If the phone was totally dead before it refused to charge initially, then the refusal to charge is due to the fact that there was no residual charge left to bring it to a charge, because the battery completely died.
To fix it, kick start the charging process.
Remove the battery, and using a universal charger (desktop charger) charge the battery for say 10 minutes, before re- inserting the battery to the phone and continuing with the normal charging process.
If this does not work out, then problem is with the charging port. It has to be replaced. This can be done by nearby local phone repairers.
Hope it helps?
Success.

Samsung NP R70 Laptop won't charge


Most laptops will work with or without the battery and with the power adapter connected.
If the power adapter is OK, just connect it to the laptop's power socket and wriggle this plug. Does the charging LED flash as you wriggle this plug? If so the power socket may have a dry solder joint or it may be faulty. Either way the laptop needs to be dismantled to solder or replace the power socket.
