Wait a minute. What?
From what I read;
1) One wire of the AC adapter (Charger) is hot to the touch.
'.....when I touch the charge one part of the wire is very hot."
2) AC adapter checks out as far as voltage is concerned.
"I tested the charger voltage and everything is ok."
3) "Sometimes when I touch the charge appear the icon...Could it be the charger broken wire?"
Does this mean, "Sometimes when I touch the AC adapter (Charger), the battery icon appears."?
Battery is CHARGING icon?
Could it be a broken wire in the power cable TO charger?
1) AC adapter NOT plugged into the DC Power Jack, plug the power cable of the AC adapter into power.
Multimeter set to DC Voltage, and proper scale, red Positive lead to harness wire that goes to DC Power Jack's center pin;
,black Negative lead of multimeter, to wire that goes to DC Power jack's inside cylindrical metal shell;
Now gently wiggle the cable from the AC adapter, TO the DC Power Jack of the laptop.
Do you get an intermittent reading?
2) Also, how did you replace the DC Power Jack? What steps did you take? http://www.dcpowerjacks.net/catalog/index.php?main_page=product_info&products_id=1291
Did you reuse the wire harness, and solder it to the DC Power Jack?
Have a lot of experience in desoldering/soldering?
What tools did you use?
25 Watt soldering iron?
.025 or .030 rosin core solder?
Desoldering Tool, or Desoldering Braid? (Solder Wick)
Side Cutters instead, and slightly shortened the wires of the DC Power Jack's harness?
(Then tinned the wires, and soldered the wires of the DC Power Jack harness, to DC Power Jack?)
Damp sponge, and cleaned the well tinned No.2 chisel tip, of the soldering iron, frequently? Used rosin solder flux?
Center pin wire (Positive), of harness cable TO DC Power Jack, was soldered to the center pin of the DC Power Jack?
Negative wire of cable TO DC Power Jack, was soldered to the inside shell of the DC Power Jack?
(Cylindrical shell, inside the DC Power Jack, that surrounds the center pin of the jack)
Sure there are no cold solder joints?
Not trying to 'browbeat' you, just am curious.
1) IF you are SURE you have the polarity correct, of the wires in the harness cable, that goes to the DC Power Jack;
,and you are SURE there is no broken wire, in the cable from the AC adapter (Charger) TO the DC Power Jack;
,and you are sure you made good solder joints;
I suspect the power correcting chipset on the motherboard, to be bad, or perhaps a Diode.
One example of the chipset I am referring to. This one is used in a lot of laptops. May not be used in yours, but gives you something to refer to when looking for a bad chipset, in the power stage, on your motherboard,https://docs.google.com/viewer?a=v&q=cache:oER5NNz8cwcJ:www.fairchildsemi.com/ds/FD/FDS6675BZ.pdf+Fairchild+FDS6675BZ&hl=en&pid=bl&srcid=ADGEEShOhWPjm_M-ROHme4iEMrztCTOd-28jNiy1hVLQQh_VOyv8zcXEVDB_iTQA6MuZO88UmRkDgjyW9j4CP2aIJ-4DS-h6JNM3lvxldeApQeecmz_DADCw1s7tmNLxfPknqX14SZP6&sig=AHIEtbS_rYUAeo_8rB9YHkW05ZjLqeH4Jg
Usually when bad the top of the chipset will be blackened, or bubbled.
A Diode is a one way valve for electricity. When they go bad it is visually obvious.http://www.mouser.com/ProductDetail/Vishay-Semiconductors/BA479S-TAP/?qs=j6bfm3UnQnzfWUXqYnsQ9LdHLayQ%2fSwFGlGUXEDAB5w%3d
