HP Pavilion D2700 only turns on once then must reset BIOS
Good day folks. Hope someone can provide a bit of expert help on this issue I'm having: a friend of mine asked me to take a look at this junkie DV2700 which would not longer turn on. The issue is as follows: you plug it in and nothing happens. If I remove the CMOS battery (which was nearly dead anyway) and THEN plug the adapter in, the laptop turns on by itself, displays the message you see pictured below and then if I hit F1 it WILL indeed manage to boot into windows (10, though it's irrelevant), which would be fine except that if I NOW turn the laptop off, the same cycle repeats: I can no longer turn it back on with the power button unless I remove the CMOS battery, at which point it turns itself on, displays that screen again...bla bla. That's another thing I need to mention: that power button does not work AT ALL - not even to put the thing in standby after it's booted. The problem also works the other way around: if I let the laptop idle enough and it DOES go into sleep on its own, pushing the power button doesn't wake it up - I have to pull the plug and CMOS battery again. No, it's not a physical problem like a bad button or busted connector - I tested it. I also CANNOT access the BIOS screen no matter how hard I try (yes, the keyboard is fine). I tried flashing the BIOS using the utility found on HP's website, which was successful, but ultimately didn't change anything. Obviously I've tried all standard procedures like removing RAM/HDD, etc, none of which made a difference. Has anybody had this issue before ? Is there anything else I should try ? Browsing the interwebs didn't prove to be of too much help - just generic advice on there, so I'm thinking something perhaps a little more of "expert" level....it's junk anyway so might as well try stuff out on it 
Cheers.
