Hi, i cleaned the board and checked the traces add some solder mask, missing parts are on the board now - according to locations and values from pictures, skipped RT1136 and RH133 since both of them are 0 ohm and on MB the traces are bridged.
There is one more issue now, it turn out the UH8 (bios) didn't survive and its not responding any more, i already found the bios file, unfortunately i don't have 25q256 around so i need to order it.
I'll keep you updated, thank you for your support....Leave a comment:

Hi i have some trouble finding good quality photo of that MB and i need some support/opinion in my topic "Dell Precision 5540 LA-H331P Rev: 1.0 lost components" - the question is should i populate all missing components marked with arrows ?
Or maybe someone have good quality pictures ?
My ideas from above:
1. +3V_PCH; PCH_SPI_CS#0 - populate
2. PCH_RSMRST# ; PCH_RSMRST#_EC - ?
3. PCH_RSMRST#_EC; PCH_RSMRST#_R - ?
4. GND; PCH_RSMRST#_R - populate
5. PCH_RTCX1; PCH_RTCX2 - populate
6. PCH_RTCX1; GND - populate
Thank you...Leave a comment:

MSI Pulse GL66 11UDK
Hi everyone,
I have here Pulse GL66 11UDK, when i connect charger the power led is blinking slowly 3 times after that no sign of life.
When i disconnect the KB ribbon and Cmos battery laptop boot without problems every time i connect and disconnect charger.
When i leave the KB disconnected (assuming its broken) and connect only the Cmos battery, laptop power up once and after disconnecting and connecting charger again no sign of life expect 3 slow power led blinks.
Tested with and without battery - same behaviors.
Bios cleaned ME and updated to newer version.... -

HP 840 G6 - no backlight
Hi, i have here HP 840 G6 (6050A3022501-MB-A01) with no backlight and i can't find the problem which causes it. Laptop is booting it gives image without backlight on LCD, it gives image also over HDMI.
What i did already:
- check all fuses on mb(ok)
- measured on LCD mb fuses, ok, one have 11,99v other one 3.3v
- swapped the LCD with working one (no effect same problem no backlight)
- searched for short (in connector area) on mb couldn't find anything
- checked connector pins on both sides - ok
- BIOS updated to newest version
