Re: Asus x555LD touchpad not working
so this is a strange kind of touchpad problem that does not give any clue. thus, more tests should be done to find a clue to discover what component is defective.Comment

Re: Asus x555LD touchpad not working
DRIVERS! I had same problem, trackpad wont work. Bugged drivers or something windows related.
Uninstall drivers from device manager and remove trackpad software. Restart PC, it should install generic drivers.
this asus notebook is total garbage. GT820M throttles with fresh thermal paste. Trackpad problems. Stupid motherboard design.Comment

Re: Asus x555LD touchpad not working
Well, i call it grounding tape.Its the fabric conductive tape in the picture above the white sticker on the left (its an acer netbook).Without that tape or a jumper wire its erratic or doesn`t work at all .Theres another large GND pad on the right where i can run a jumper wire to the surrounding metal bracket .Attached FilesLast edited by SMDFlea; 04-08-2019, 04:19 AM.Comment

Re: Asus x555LD touchpad not working
It should be asus smart gesture or asus support device (generic drivers).
Try booting latest hirens CD with linux or mini windows 7/10, they should have generic drivers. To test if it's windows/drivers problem.
because in my case it was exactly it - Drivers.Comment

Hey guys,
Just purchased a CF-20 (mk1) supposedly was all working. However, the seller had done a fresh install of windows 10 but did not install any driver. Seller was adamant the trackpad/touchpad was working.
The touchpad/trackpad does not work. No led lights near the trackpad. The keyboard works, the USB 2 port on the base does not work, The USB 3 ports will recognise a USB 3 flashdrive but did not recognise a USB mouse. The ethernet port on the keyboard section works.
The USB 3 port on the actual tablet section works with no issues.

Hi,
I have an really very weired issue with ASUS ROG STRIX B550-I GAMING.
Some NVME (PCIe) SSD's are not working correctly in the second M.2 socket. An example of it is the SAMSUNG SSD980 1TB NVME SSD.
Some other NVME (I have only smaller ones) disk do work without any problem, also SAMSUNG disks, eg an MZVPV128HDGM-0000.
The behaviour is also really very strange, i.e.:- The disk shows always up in BIOS - so it is recognized, so far so good
- POST-ing with this disk with fresh Windows 24H2 installation (done in the M.2_1 socket) in the M.2_2 socket

Hi guys i am new to macbook repairs (i mostly do microsoldering on iphones and android devices. I need your assistance with macbook a1706 (touchbar edition) that came in without touchpad and keyboard functionality. External keyboard and mouse does work but the keyboard and touchpad on the macbook does not work. I changed the touchpad flex, also replaced the touchpad but the issue persisted. I then measured voltage on the board and found that PIN 44-50 of the touchpad connector (J4501) got 11.2V instead of 12.6V. Those pins required 12.6v and they get their 12.6v from PPVIN_S4-TPAD_FUSE . I measure...
