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.

Respected Sir, I want Intex notebook model no m73sr charging circuit diagram, Please help me.

The power supply (the inline module built into the power cable, which may be two pieces, is probably bad. That is the most common problem. Contact a dealer to get a replacement (the model number is on the power supply module) or get a universal one, set the amps the same and select the correct adapter. It will come with several so it will fit the power receptacle in your notebook.

I have a gigabyte p4 pc, when i power it on the fan runs but it gives out a continuous beep. checked ram, processor on another motherboard, cleaned the motherboard, checked for loose cards and cables

The continous beep usually means a memory failure (RAM) or video memory if a plugin card is used.

Check to be sure the unit sees all of the memory, a weak power source( without AC adapter) could cause a partial failure of one memory card.

Another fault would be that the battery is very low on charge and won't accept any charge.

BAD Battery.

hope it helps

I have to say that if you get no power from the mains adapter and no power from the battery that is charged up, there is not a lot left that is user serviceable on the mother board.
Contact for technical advice and a possible repair.
Hope you get it fixed soon.

Dear sir do you happen to have circuit diagram for acer aspire 5570 , the 19v dc power in connection pin broke in two. i need the schematic diagram for this power system board which lead to the...

Connect the adapter to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard.
This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.

Vostro 1000 wont charge also 2nd machine same model has a ic blown on mainboard where can i get a schematic diagram also is there a general known fault with the charging circuiton this model . Rgds

Schematics for Dells are generally unavailable.
The not charging is normally due to a failure on the charging circuit or damage to the power plug (If ac adapter will not run system or if you have to play with the power connection.)
Replacement motherboards start at about $75
