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. ThanksAnything happen to it before this state in which it will not turn on.... dropped, liquid spilled in it, bad storm with lightning, it was acting up for a while and finally wont WORK at all etc?Bad thunderstorm with lightning. Computer was plugged in but I believe it was off. Battery was not in it. Had big thunder BOOM, tv turned off everything came back on computer was plugged into a power strip with a "surge protector" You can try leaving the battery out of the laptop for a day and then reintroduce it and see if that works.

But first, Does any power indicator lights light when its plugged in to charge? Have to tried this laptop powered off a different outlet, known good outlet?

If you have a good name brand surge protection power strip the good news is that they might cover the replacement of a computer that is damaged. What brand is power strip that has the surge protection.

Lastly some home insurance covers replacement of damaged electronics from lightning etc so if you had to get a new computer you might be able to file a claim and get a replacement that way.
