Hello,
I have a Samsung NP300E5C-S01PT with a board problem.
After some minutes (10-20m not always the same timming) PC turn off itself.
Things i have tested and discard:
- Power adaptor is good, tested with 2 same happen
- Battery is in good condition capable of 4h and get charge without problem
- With or without battery plugged same happen
- Battery only operated same happen
- Power adaptor only operated same happen
- Power adaptor and Battery operated same happen
- CPU&GPU cold 40ºc-60ºc - Not a thermal issue
- Same happen if pc is inside BIOS menu (Not a SO Problem)
- I tried to remove HDD, DVD, Wireless, battery, monitor [Only board and ram was connected] - Same happen
After this checks i'm sure it's something related to board.
The problem is strange since PC perform well, fast but after sometime it suddenly shutdown like a power cut.
Battery is inside and work with it so it can't be a power adapter problem.
When PC cut off power we can immediately click on power button and it will boot again with no problem. When turn ON again the time to power off will be almost the same, so can't be a heat related component since we can use it about same time as a cold start.
Anyone experienced same problems in other models?
I have attach the schemantics, it have a power management block, but what to search for if everything is normal while working?
