HP G72 turning off randomly
Hello everyone!
Laptop is a G72-b10sv. Had come again in the past with the common Ati 5470 gpu problem. Did a reflow and last about a year with every day of light use. Because of the simple use needed, i convert the board to UMA, transfering the two resistors(RI55 to RI51 and RI53 to RI56 and clearing the jumper PJ19. Also replace the thermal paste and the thermal pad on HM55.
Install a new ssd and begun the windows installation from scratch, all went as it should, install everything and after an hour the first turn off occurs.
After that, it turns off completely randomly, some times not even past the windows screen without turning off, others can stay on for 3 hours, others for some minutes. Trying with other known good ram, replace the cpu with same one (P6100), update the bios to final, temps are excellent. After i suspect the HM55, did a reflow there, but nothing change.
I saw that many others have the same problems with this board (pm_i_hpc_s mv_mb_v3). Its the same for G62(15.6) and G72(17.3) laptops but noone has an answer to what is causing this.
Anyone have an idea what is the root of the problem?
Thanks for your time
