  • 820-00239-09 slow, not liquid damaged

    i took out the board, not water damaged at all
    very slow, fans are full speed, otherwise works

    with HW monitor it says that 3 values are 33 degrees than 5 sec later it shows 129 degrees, it keeps cycling those values for the cpu related temps

        solved, U5870 and the area looked perfect, but that is the chip doing all weird stuff, cause the temp issue jumping up and down was cpu proximity and around related, so i desoldered the chip, right away 3 pad came off, i did not force it , the chip was lifted after the solder melted, then the 4.th pad off easily too, i wired them based on the boardview and now works fine, laptop was not dropped, i think the pads are that crap quality
