Hello .

We have MB Lenovo G50-30. The laptop was water damaged. We repaired HW, laptop turn on no video. So we flashed BIOS, after BIOS flash laptop turn on normally with video on output but only for 2-10 times then video goes off. We tried to reflash BIOS and EC bios, we tried to replace the chip for a new one. All the same laptop turn on several times after short time there is no video again. After next flash video goes on, after 10 times turn on video disappear. WHen we flash it again it works again.
There is no short on +3V on BIOS, all the PINS and voltages on MB are OK. It´s just BIOS issue, we don´t know why the flash automatically damage after few turn on´s.

Please did anyone experienced this problem? We do a lot of laptops never had this problem, we need to solve it for our customer
