Save All Around by Powering Your Computer Down
The sleep mode on your computer is designed to keep the machine on while drawing a small amount of power. This only costs about $50 more per year on your electric bill, which seems low, but the true cost of leaving it in this mode may actually be higher.
According to our experts, you shouldn't leave your computer on standby if you're going to be away for more than an hour. Doing so can result in more harm that good. Your memory is still fully functioning, which can lead to overheating and damage, so it's always better to fully power down and let your machine rest.
Turning your computer on and off won't cause damage. These days, laptops and desktops are designed to withstand 40,000 power-ups and shutdowns before failure. That's the equivalent to turning your computer on and off 15 to 22 times per day for up to 7 years.
So, when it comes to your computer, be mindful of letting it sleep for too long and power down instead. Otherwise, the low-cost convenience of having it on standby may result in a higher cost in repairs down the road.
