can fluctuating electricity affect computer

Yes I agree, a UPS will give you time to turn off your computer properly. And to add to that, you need a good AVR or Automatic Voltage Regulator, AVRs prevent sudden electrical surges going to your computer, it's a must especially for desktops. :)

@ fatlex, Since no one can predict power cut off not even the distributor themselves, they have no idea when their power will trip off due to some unforeseen events so we have to be ready at all times. I think most appliances especially computers needs voltage regulator. Their function is to stabilize the current flow in case of voltage surges. Yes, when there's power cut off UPS still have remaining power that let's the computer to shut off safely. @ Eppie, Yes, the AVR regulates the flow of current in case there's voltage fluctuation. I guess computer stores oblige their regular consumers to at least plugged their computers to an AVR just to be safe.

I also think it is good to have UPS for computer and UPS helps to save work and computer when there is electricity fluctuation.

Yes, you right the power supply in our area is unpredictable. At present I only have PC and is connected to a voltage regulator that would take care of the surges. UPS is good but I need to save some to have it.

But I think when voltage fluctuates sometimes our computer shuts off itself because of the limited supply of electricity. So it's a preventive action of computers if the supply of voltage becomes low to prevent any damages to the unit. Other members recommended UPS(Uninterrupted Power Source) or Voltage Regulator.

Yes, because of voltage fluctuations many appliances especially computer suffers much. So it's much better if it's connected to a voltage regulator to maintain the normal flow of electric current. It's good that you don't use your laptop, connected to an outlet to prevent it from damage in case of electrical surge.

I think battery packs is necessary especially for computers in big companies to care for their computers. And most of them also have power generators as back up in case of brown outs. Yes, it's better to asked computer suppliers on how to keep our computer safe from electrical surges.

Yes, my friend as some members have said it would really affect our computer.So it's better to use voltage regulator, the price is much lower than dealing with a damaged computer. I guess in most offices they have this thing (UPS)a power back up just in case.

Yes, it do affects our appliances when there's surge of electrical power. It usually affects the motor and could burn it if the power is unstable what more if it's the computer. So if possible plug it to a voltage regulator that helps stabilize and maintain the power supply.

Yes, your right the unstable supply of electric current that gets into our computers affects it's performance. So it's better to use voltage regulator for our computers to keep them from damages in case of electric surges.

So, you have experienced it already. Yes, most technicians said so, that is why it's important to connect it to an AVR and if possible to an UPS just in case, so we have enough time to shut off the computer.

Yes, fluctuating electricity have great effects not only in our computers but also to some of our home appliances. At the moment I have only bought voltage regulator to regulates the power surges in our area. Yes, UPS is a good suggestion to protect our computers from electrical surges.

Yeah your right, we can actually see the effects of fluctuating electric current when our lights are on. It dims as if going off, what more to our computers if it experienced the same thing. So, it's advisable to use an AVR or UPS as a precaution.
