Product description

This chip is used in notebook power supplies DELL 65W (watt). For the laptop to recognize the power supply as original.

DELL power supplies have an additional needle  in the power connector. Through this contact, the laptop reads data on the type and capacity of the charger. If the read out type of charger or its capacity is "not suitable" - the battery will not be charged.

Likewise, the battery will not be charged if the data cannot be read due to the non-originality of the power supply (it does not have a corresponding chip). This was done in order to "protect" the buyer from low-quality, cheap "analogs", and simply "analogs", the money from the sale of which does not come to DELL. An original PSU usually costs about $20 - $60, depending on the model.

 

To charge the battery, it is necessary to transplant the chip from the original unit to the non-original one.

But a difficulty arises: in most "analogs", and simply in universal power supplies, there is no third wire from the charger to the laptop. There is only "plus" and "minus". And the second difficulty is to get the third wire to the central "needle".

 

Therefore, there are two options:

1. Use a wire from the original unit (with a third conductor).

2. Solder the microcircuit directly into the laptop.

 

The data in the original block is stored by a microcircuit. It contains 512(1024) bits or 64(128) bytes of EEPROM and is written once at manufacture.

In the original block, the connection diagram is as follows: the first contact is soldered to ground, the second through 130 Ohm to the center wire 'ID ", the third is not connected. A 130Ohm resistor is soldered to the center contact. (According to the connection diagram)


Now, when connected, the BIOS happily reports on the presence of a 65 or 90-watt (or other) DELL power supply (depending on the installed chip), and charges the battery accordingly.

 
VERY IMPORTANT!!!

Do not mix up the connection method, otherwise the chip will permanently stop working.
