In WINDOWS there is indicator that battery is charging but stays on 0% full. Battery is ok. It`s charging normaly on other notebook.
There is 8-pin battery connector with this voltages when battery is present:
3.5V, 3.5V, 3.3V, 3.3V, 0V, 2.11V, ground, ground.
What voltage must be on connector to charge battery?
I thought that there must be some chip controlling battery charging. I found only chip with this marking and no datasheet:
BQ 74740
TI 82W
ZJ6D
Does someone knows is this guy responsible for charging?
The exact model is: HP Pavillion DV7-1000EF.
Check the charging circuit.
I found datasheet for BQ 74740. It`s: Host-controlled Multi-chemistry Battery Charger with Low Input Power Detect
Available at: http://kr.ic-on-line.cn/IOL_BQ24740/PdfView/1220202.htm
As seen on datasheet there is direct link to Battery that is floating from +3.5V to 12V and back.
I`ll search for replacement and reply the result.
Thank you Olgert for support.
