Thank you Worked like a charm!

Hi, Dumped the rom, but no $SVS present, I am confident that the dump is not corrupted. Anyone has a clean one? Or knows what else I can check? https://drive.google.com/open?id=1iTixL-8HJCAmWbtaFRysoyV4mlZ0tKCT

2informaticos Thank you! As I started to look into ways I can check the voltages while running the os, I noticed that the issue is with the flex cable (touchpad to mobo). I had a similar unit - new flex fixed it Thanks again!

Thank you 2informaticos R4850 33.4 ohm R4851 33.6 ohm R4852 33.3 ohm R4853 33.3 ohm The resistors seem fine I guess U4810 1 3.33v 2 3.30v 3 0v 4 gnd 5 3.33v 6 0v 7 3.33v 8 3.33v Measurements taken with only power and the fan connected

Hi again and Happy New Year! The same unit that had a backlight issue. (https://boards.rossmanngroup.com/for...-liquid-damage) Just got the password from the client. on login screen both touchpad and keyboard work perfectly The moment I log in, they are gone. I am hoping it is a common issue...

Thank you JohnB8812 ok, at the moment I have continuity from A5 to XW7720. The brd file suggests that XW7720 has two pads and the second pad should connect to pad 2 of the D7701 So I am guessing that your advice is to run a wire from XW7720 to pad 2 of D7701

Chhers, after I remove the driver I will pull the wire there then put a new driver, this should do it hm?

Cheers! I will get the driver and check it!

It's a pad! I was expecting a component looking at the brd Yes, there is a continuity between ball 5 and that pad

Thank you for all your help so far! You mean XW7720 is there? Maybe I am thinking of something else, when I look at the boardview it is showing me this But there is literally no room on my board for it as you can see on my previous photo. I have a feeling I am using some bad brd file :/...

XW7720 is not present on my board for some reason - looks like its some different variation Tried scratching what seems to be a hidden pad but I am not sure if I did it right. No continuity. between ball 5 and D7701

Yes, the picture is present when I put the light behind the screen Q7706 1 - 8.12v 2 - 8.12v 3 - 2.67v 4 - 8.12v 5 - 8.11v 6 - 8.12v D7701 both ends 8.08v F7700 similarly, both ends 8.08v I can't seem to find the test point for the 5th ball of U7701, my layout seems slightly different from...

Hi Got this board yesterday D7701 C7796 C7797 L7701 all looked awful so replaced them, but still no backlight, otherwise the unit is functional Please assist

apologies, there are other differences on the U3740 Pin 1 3.43v Pin 2 0.994v Pin 3 3.288v Pin 4 0v Pin 5 GN Pin 6 3.25v Pin 7 starts at 1v and slowly goes down Pin 8 0v Maybe I didn't do it right? J3700 Pin 1 3.33v other power pins share this power line it seems. I am sorry to be so...

Hi Swapped U3740, Pin 8 is now 0v, Pin 6 3.15v other pins are the same, still the same outcome :/

sorry, Pin 3 - 3.28v, pin 4 - 3.43, pin 5 - 0v, pin 7 - 0.022v, pin 8 - 0.993v

U3740 Pin 1 3.4v , Pin 2 0.98V, Pin 6 3.22v While on

3.3v on the J3700 PP3V3_S0SW_SSD_FLT I hope that is the one.

J3700 i think! Let me check it now
