lenovo z470 does not display ...
lenovo z470 does not display , current about 0.7A , Power on , checked one inductance has 0V voltage to CPU , Power chip is ISL95831 , Integrated graphics is 0V voltage . According to the experience , we usual replace cpu , rewrite bios and replace HM65 chip . Completion of this three-step , but it is still same fault , then found the network card is very hot, and removed it . the current became 1.3A ,Lcd started display . Prove that it is a bad network card . it made HM65 chip can not work to offer voltage for Integrated graphics . Your loyal friend - Pinkney , http://www.htic-tool.com
