By reading this and your other posts, I'm making an educated guess that you're not in the US. In some countries, in different locales, power quality is an issue. I think when you said you were looking for something under 100 USD. you might have been thinking of a battery backup/surge protector combination. Something along these lines:http://www.apc.com/
Unfortunately, if you have truly unstable power, You need a voltage regulator/line conditioner. These are inexpensivehttp://www.apc.com
Note that the one's I linked to are for 120 volts US. APC is a world wide company, so availability should not be a problem
Where are you from, if I might ask?
why won't my laptop work?
Having grandkids is God's way of giving you a 2nd chance because you were too busy working your butt off the 1st time around
Do not send me PMs with problems that should be posted in the forums. Keep it in the forums, so everyone benefits
