Lenovo G575 Power Up Problem
My Lenovo G575 won't power up after shutting down yesterday. The power level was very low when shutting down because I was using it without plugging in to the main supply. I think that might be the cause. I also tried the power reset method of taking out the battery & pressing the power button 11 times and then holding it for 11 seconds. Can any one help?

First off, I think that it is not a good idea that you press the power button 11 times. This might break the power button of your computer. Your computer might not be having enough power supply to boot properly. I believe that there is a problem with the battery since you have mentioned that the power was low before it was last worked. I suggest that you replace the battery of your Lenovo G575 laptop. You can buy a compatible battery at Amazon.com. This is the link:
