I have an hp envy touch smart laptop. It won't turn on. I went through all the hard reset protocols and contacted support. Diagnosis is its more than likely mother board. I did a search on other ALTERNATIVES BEFOR taking it in for an expensive repair. A friend told me that I could try removing the clock battery and plugging it back in and then I also found a video that talked about I believe replacing the bios battery. Not sure if bios battery was the term that was used. Basically the guy unplugged the power source that went directly to the mother board and then he remove like a CIRCULAR piece that I think was just stuck to another board and then when he replaced it he just pressed the circular end back in place. Then he plugged the other end in and then reconnected the power wire back to the mother board. If any of this SOUNDS familiar as a viable solution to try before taking it yo repair or if anyone can fill in any blanks or has other suggestions I would be most appreciative. I've also heard the term bios reflashing but not quite sure what that MEANS. ThanksYou already have an active thread on this topic. I'm locking this one.
