إصلاح مذربورد لابتوب HP Pavilion 15-E - إصلاح صعب.

In this important video, we repaired a motherboard model DA0R62MB6E1 REV:E Especially for the HP Pavilion 15-E laptop, as well as the HP Pavilion DV7 R62 laptop. The problem with this laptop is that it does not work at all, and when we connect the charger, we notice a flashing on the LED of the charging socket! After taking the initial measurements on the main voltage line, it was found to be completely safe We then moved on to inspect the main power circuits, starting with the 3 and 5 volt circuits, but they were out of order! It was necessary to analyze it carefully, and it was found that the activation signal for these circuits, which is S5_ON, and whose source is the İO CHİP KB3940QF A1, disappeared. After that, we entered into a spiral of doubt and follow-up to the source of this signal and the elements related to it. The almost certain doubt, through the data resulting from raising the measurements, led us to make a decision to replace the chip. Completely, but unfortunately we obtained the same result. We then moved on to more in-depth measurement and tracking operations based on the same previous data, which led us in the end to discover the cause of the malfunction and repair it completely, and the motherboard returned to life again. Praise be to God. A full examination of the device was also conducted after its repair was completed, and it was Everything is fine, thank God We wish you an enjoyable and beneficial viewing Watch also Lenovo power splitter with weird shorts.    • لينوفو فاصل باور مع شورت غريب.   LA E541P No Power - Lenovo power splitter repair    • LA E541P No Power-اصلاح جهاز لينوفو فاصل باور   Hp pavilion g6 no power    • Hp Pavilion G6 no power   #Laptop_repair #no_power #Motherboard_repair #Mohamed_Aram #Reference
