Laptops are we going to fix this is a laptop that normal life but could not be charging. The indication is (In this article we take the example Asus A43E):
1. Can a normal life using the charger,
2. Can not be turned on without the charger
4. Battery normal, can be tested on another laptop
3. When entering the windows (in this instance Windows 8) indicator normal charging but remained fixed at 0%
Asus laptop could not charging
This problem is caused by the armpits charger IC normal, for sure we have to follow the steps below:
Equipment required at step this service are: Solder, solder vapors or blower, tin, liquid flux, multitester or avometer and other ancillary equipment.
1. Disassemble your laptop and take mainboardnya
3. After Charger installed, the laptop should not turned on, and measuring the voltage at the point of battery connector positive (+), on the outs ic power charger or mosfet (V.bat), and the number 17 on the foot and leg charger ic number 2 respectively each of these points in normal conditions should be pointing to the approximately 19 V.
2. Take the power button (power button) to facilitate the tester's, then plug the charger, be careful to put the mainboard in a safe place to avoid a short-circuit resulting in damage worse.
In the picture above indicated IC charger with 21740 series (Asus A43E).
The equipment we need for the service of this laptop is Solder steam or blower, ordinary solder, liquid flux, ic lifter or chipset, ebberapa multitester and other supporting devices such as tin etc. Similarly, examples of how to determine and fix a laptop that can be charging but at 0% and can not be turned on without the charger, may be useful.
4. The conclusion is that if on such points no voltage, but on pin 2 of IC charger is a voltage of approximately 19V, the charger IC ask for the dressing, simply buy a new or taken from another laptop as his successor.
