Hello colleagues. I have a laptop on the table as the title is included without the image takes approximately 1.2A. Replaced NB 216-0752001 new because in these models is usually flawed though the old heating did not result in a full run. After replacing the laptop still does not work searching for the cause came across a compact transistor U39, I mentioned it to the case, reprogram the bios to no avail. Tensions in the standard charging generators too. Processor memory podmieniałem reprogrammed bios reset the cmos.
Please help me because I was stuck.

U27 (MX25L1605) replace (W25Q16)
