I have a motororola model MBP8 PU babby montior quick working after power went out they turn on but but don't work


Is it plugged into a surge protector? When the power comes back on to a lot of residents at the same time, a power voltage spike occurs that can damage electronics. All items that have any electronic circuits, need to be protected by a surge protector. Surge protectors do not protect against lightning strikes.

I had a power outage & now my pc won't turn on.


It is possible that either the power supply or the motherboard is faulty.
Try swapping out the power supply (borrow one if you can) and if the PC power LED does not light up or the PC boot up, then you need a new PC.
I suggest you get a surge protection power board and connect your new computer to this surge protection power board. It will protect your computer from power surge problems.

    On HP computers, I believe that this means that the power supply or the motherboard is bad. I assume that the outage was due to the thunderstorm and you may have received a surge. In your manual, there should be diagnostic light codes where they will outline the exact meaning. Again, to the best of my knowledge, this means that there is a bad power supply or a motherboard.

    OK FIRST A POWER SURGE PROTECTOR WILL ONLY PROTECT YOU 7 % OF THE TIME, WHICH YOU JUST REALIZED. SO YOU NEED TO BUY A BATTERY BACKUP ALSO KNOWN AS A UPS.... I CANNOT STRESS THIS ENOUGH. BRING YOUR PC TO BEST BUY AND THEY WILL TEST YOUR POWER SUPPLY, IF IT TESTS OUT OK THEN YOU BLEW SOMETHING IN YOUR MOTHERBOARD. GET A BATTERY BACKUPS/UPS!!!!!!!!!!!!!!!
