Before i salvage this lenovo U300 for parts i just wanted to ask if anyone maybe experienced a similar problem and knows a solution that might work. If i turn on the laptop without ram inserted, fans speed, no beeps, no image (as it should be). If i insert ram, the computer will turn on for a second and then turn off, then turn on again for a second and turn off and so on. There is no image, not on internal or external display. One thing to note is that the computer is charging the battery as it should, but when using battery instead of cable, it makes no difference. Things i tried: - unplugged everything non essential (like hdd, wifi, itd.) - tried different ram - tried with/without esata 32gb cache - tried with/without 3V battery, unplugged it for 10 minutes to clear cache - checked 3V battery, its showing 3.0V - tried soft reflow on both cpu and integrated gpu (8 mins with hair dryer) - tried different power suply Anything else i should try before salvaging it ?
