      Dont know wtf is going on but i replaced PD1 which measures good both pins 700OHM and now charging and starting. ID pin voltage goes to 0.65V. Consumption is 0.25W and after few seconds go to 0.10W. BUT when i connect keyboard again nothing works and consumption is still 0.35W

      is there something bad with EC?

          Normally when ID pin touches 19V-EC gets damaged. So worth replacing the EC.

              Funny thing is that owner dont tell me that keayboard was defective before, so EC works fine.

                  Converting HP EliteBook 840 G7 non-touch to touch if possible
                  by trepachka
                  I am trying to convert a HP EliteBook 840 G7 notebook from a non-touch to a touchscreen. I purchased a complete touch LCD assembly with a screen/back cover/bezel/video cable and swapped it out with the original non-touch LCD assembly.
                  The screen works but the touch does not. I know the new LCD assembly is completely functional because we tried it on a similar touchscreen EliteBook 840 G7 and the touch works there.
                  I contacted the seller and he said screen conversion like this will not work due some difference in the motherboard for non-touch and touch capable EliteBook 840 G7.

                  Lenovo T460 Only Charges on One Charger
                  by motormayhem
                  Laptop Question
                  Hello,
                  I'm working on a Lenovo T460 that has been having trouble charging as of late. Its worked well since I've owned it for a few years. When I went to use it the other day it was dead and wouldn't turn on (was sitting on an Anker 65W GaN charger). After some fiddling with the charger I got it to turn on and start charging, but seemed like the charger was not working as it should (took a few plug and unplug cycles to get it to start charging).

                  A day later it was dead again and wouldn't boot/charge no matter what I did. No lights or anything when...

                  Surface Pro 4/5 - no touch after LCD change
                  by Prott
                  Hello,
                  I have a question that's driving me a bit nuts recently.

                  Is the touch board on Surface Pro 4/5 somehow married to the motherboard? I have a few Surfaces that, after the touch board change, lost all touch functionality.

                  - I tried flashing the bios (simple ME clean from a known good bios, previous bios didn't have an intergrated hub enabled), reinstalling firmware, reinstalling windows and even new touch boards.
                  - In one instance, after I tried to troubleshoot by using a known good screen + touch pcb combo on a Surface that lost touch, the touch board...

                  by Document Archive
                  The ISL88739 & ISL88739AHRZ are a highly versatile combo battery charger
                  configurable for operating as either a Hybrid Power Boost (HPB)
                  charger or a Narrow VDC (NVDC) charger, supporting 2-, 3-, or
                  4-cell batteries. Both configurations allow the battery to work with
                  the adapter together to supply the system load when it exceeds
                  the adapter capability, referred to as system Turbo mode. HPB
                  charger configuration reverse-boosts battery energy to the system
                  bus to help the adapter provide the system power in Turbo mode.

                  how to prevent a connected charger from draining battery when not charging?
                  by flat-earther
                  I have an RC radio handset(Taranis QX7) which doesn't have internal battery charger which means I had to remove the battery every time I needed to charge it.
                  So to improve it, I added a 15W USB-C charger board(link) inside and soldered it to the same connector on the PCB where the battery plugs into, great, now I can simply charge it with a USB-C cable.

                  but the problem I found is that after the radio sat for two weeks without being used the 2S 18650 battery that I'm using was at 4.2V!
                  So the battery is backfeeding the charger and being drained.

                  How can I prevent...
