Nothing happends when i press the start button. It seems during the night there was a power shortage (computer was on) and now it won't repsond at all. there is a green light on the lower right corner of the motherboard blinking continously. If i recall correctly that light should be a steady one, not blinking.

Your MotherBoard has 2 LEDs in the lower right corner, each designating a power condition. They are labeled LED14 and LED21. LED14 lights when there is a power source connected. If this is the one blinking it likely indicates a failed power supply. If you have an alternate power supply available that is comparable in power supply capabilities I would try that. LED21 lights when the system is powered on. Replace the power supply.

    Did you try a different power supply with your suspect motherboard? The owner's manual for your motherboard does not state what a blinking light means, so I guessed it would mean bad power supply. The manual also gives a procedure for you to send the motherboard in for repair, if that is an option for you.
    The fact that it doesn't power up would also indicate the same. If it's not the power supply then I would suspect a damaged motherboard from the power "shortage" (is that supposed to be outage?) Oftentimes when the power goes out, and more importantly when it comes back on, there is a surge (hence the proliferation of power surge protectors for just this reason) on the AC line that can damage sensitive electronic equipment. If there is ever stormy weather, especially with lightning, in your area and you have a history of power outages, it is best to disconnect your computer from both the AC and phone/cable lines. I have seen MANY, MANY fried computers from just this problem alone.

My Acer Aspire M1201 won't turn on.

More than likely your power supply got fried from a power surge during that storm anyway. You'd be surprised at how worthless most surge suppressors are these days.

Sounds like the pc power supply is bad... U can replace it, but if supply went out it may have damaged the motherboard. In future, have monitor blank off automaticlly and install UPS to supply pc. HP has histroy of weak power supplies.
