Acer Aspire 7 A715-71G. Not starting up.

Evening all,
I have an Acer Aspire 7 A715-71G which recently stopped working. When pressing the power button the blue led light comes on for 5 seconds, but nothing else. No screen activity, no fans and no keyboard backlight. When the charging cable is plugged in the orange led lights up and seems to be charging.

I tried all the simple solutions myself, the battery reset button and holding down the power button for 1 minute etc. I then took it to a local repair shop as it is out of warranty by 3 weeks, who diagnosed the issue as an "reversed IC" likely caused by a power surge and informed me that it would be likely be economically unrepairable. Annoyed but accepting of its fate I took it home.

This is where the story gets a little interesting. A week after the laptop first would not turn on, my daughter opened it up and pressed the power button and it booted up, connected to the internet and worked perfectly fine, keyboard backlight, fans, everything was as usual. I shut it down after a while and went to work. 8 hours later, upon getting back from work I went to boot it up again and the laptop reverted back to the original issue.

So my question is, would a reversed IC mean that the laptop could not boot up? In which case the diagnosis must be wrong and secondly what could the problem be if the first prognosis was not the cause of the problems?

I am not too technically minded so apologies if I have missed any vital information.

Many thanks.

    Check the mainboard safety switch just below the RAM slots. It has to be fully depressed by the base cover to power the mainboard.  The base cover will probably have to be removed to access it. Jack E/NJ

    I have attempted to turn on with this depressed with no luck. First attempt the orange flashing charge led to a solid orange light. Then a few minutes later when I tried a second time it changed it from a flashing orange led to a solid blue light. On both attempts when released the led returned to a flashing orange state when plugged into the mains.

    Remove the mains charger plug. Remove the battery connector from the mainboard. Then start tapping the springloaded SW2 normally off safety switch in rapid succession for a minute or so to try to clean up its contacts. Reconnect the battery. Replace the back cover. Try to make sure a protrusion inside the cover presses firmly against the normally off SW2 switch to keep it fully depressed in the on state. Then plug the charger back in. You want a steady orange or steady blue charging LED. No flashing orange. If steady orange or blue, first cross your fingers and hope for the best. Then have your daughter press the power button to try to turn it back on. Good luck. Jack E/NJ

    Nope no luck. It's annoying as I know there is the ability for the laptop to work. Had it never turned back on I'd have got over it already. Thanks for your help.

    Had a look around and seeming although I had the back off the laptop and I can't break it anymore decided to have a fiddle. Bear in mind I have no idea what i'm talking about here.

    One suggestion was to remove the CMOS battery to reset the BIOS. Upon being unplugged (with the main battery also removed), I decided to press the power button.

    The laptop is now on again and seems to be working again. Apologies to be a pain, but any idea how to make this a permanent resolution?

    Thanks!

    >>>any idea how to make this a permanent resolution?>>>

    Congrats. Might've been a Win10 update that also fiddled with the BIOS firmware. But your daughter's earlier successful boot sorta conflicts with this possibility. Intermittent issues like you've described here so far are hard to pin down. And still suggest a hardware issue lurks somewhere inside. Have you also repeatedly tapped on the normally on spring loaded switch that's in line with the battery reset pinhole?  Again, the battery or charger should be unplugged while attempting to clean this switch.

    Problem returned again this morning. Tried the switch for the battery reset too. Must be a lasting intermittent problem. Back to the search for a new laptop then. Many thanks for all your help.
