LENOVO G585-DEAD-AWESOME CASE STUDY

[arshad]

GOT THE UNIT AS DEAD.
[hidden]CHECKED 19V, 3V 5V ALW WERE OK. RTC SECTION WAS ALSO OK. NBSWON# SIGNAL, DNBSWON# SIGNAL WERE ALSO OK. PWRBTNOUT WAS ALSO OK. SLP_S4 & SLP_S3 SIGNALS WERE ALSO OK. BUT IT WAS THE POINT TO NOTICEABLE THAT THERE WAS NO SUSP. CHECKED THE SUSP BY JUMPERING FROM 3.3V ALW. THE MB WAS GOT TURNED ON WITH BACKLIGHT ON BUT NO DATA.

PLACE A SWITCH ON THE BOTTOM BASE (D) NEAR DC JACK AREA. CONNECTED IT ON SERIES IN 3V_ALW TO SUSP LINE. AND I WAS FITTING THE COMPLETE LAPTOP.

NOW THE TIME CAME FOR TESTING OF LAPTOP. MY FUNDA OF POWERING ON THIS LAPTOP WAS

1. CUSTOMER NEEDS TO ON THE SWITCH FIRST, WHICH WAS PUT BY ME.
2. THEN AFTER DOING ABOVE POINT NO. 1, THE CUSTOMER NEEDS TO PRESS THE POWER BUTTON OF THE LAPTOP. THEN, THE DISPLAY WILL COME WITH PROPER DATA.
3. Caution:- If the customer does not on the switch first, then the laptop will power on with blank display. For getting proper display, the customer needs to on the switch, which was put by me.

THE CUSTOMER WAS VERY MUCH SATISFIED WITH THE LAPTOP. HAPPY ENDING[/hidden]

Funny. Did you check why the EC is not issuing SUSP?
