Hi, i need a help from an experienced member. Laptop starts, works but has a random shutdown every 20-30 minutes. As soon as i disassebled it, i saw that one of the USB was broken, pins shorted. i have removed the USB and tried to install windows, laptop shutdown after 20-30 mins anyways. i have soldered another USB and then laptop started turning off every 2 minutes . every time it could be start again. figgured out that it must have been this usb that has shorted some region in HM chipset so i have removed HM chipset and resoldered another one. THIS DID NOT SOLVE THE PROBLEM. laptop again shutdown after 2 mins, i have removed usb and removed inductors and capacitors next to other USB 3.0 x2 and USB 2.0 now again it shuts down after 20-30 mins. i do not know what is the fail, every voltage is good , there is no liquid damage and HM is new. Im trying to flash new BIOS ( this is model with i7-3535 cpu and nvidia 740m graphics ) i have tried to run laptop both on integrated cpu graphics and on discrete , again same stuff happening. |

Would not have changed HM if the USB was not broken. Lesson learned :) Спасибо, мои русские братья Posted after 4 hours 20 minutes 2 seconds: Also, forgot to mention, U24 was also faulty, replaced with an older model, works fine. you can lock this. thanks. SOLVED |
