What is the best way to maintain a laptop?

1- Do not over-charge your laptop’s battery. Be mindful of this. When you charge your laptop and you realize that the battery is full, you can do these things: take out the battery and use the laptop without the battery or take out the charger and use it without the charger. I would not suggest you plug and play with the battery still in. Over charging the battery also reduces the life-cycle of the battery, and you may find out that soon it doesn’t take long for the laptop’s battery to die after it has been fully charged. When you know you won’t use your laptop for sometime, take out the battery and store it in a cool dry place

2. Clean your laptop with a dry cloth from time to time to remove any dust from it.

3. Keep your laptop always from water, liquids ,or coffee. The damage that liquids do when spilled on circuits and stuff is too bad.You wouldn’t want to spill these on your laptop.

4.  Shut down the laptop properly when you’re done with it.

Here are 10 for you to put into action...if you haven't already:

1. If you're going to travel, remove any CDs, DVDs and thumb drives that might be in your computer, and protect them properly. Also, turn the laptop off—don't simply put it in sleep or standby mode.
2. Extreme temperature or temperature swings can have an effect on a laptop. If you've just brought your laptop indoors from a very cold day, you shouldn't turn it on until it has had a chance to warm up and reach room temperature. That might take some time if it's been freezing outside.
3. A notebook's screen is its most fragile and at-risk component, and it can be cracked and damaged easily. Clean it only with approved solutions or monitor wipes. Don't touch the screen with pens or any pointer that can scratch the surface.
4. You shouldn't put a laptop close to appliances that generate a strong magnetic field, such as televisions, large speakers and even some high-tech refrigerators. You should even avoid putting your cellphone on top of your laptop while both are on.
5. Keep the lid closed as often as you can, which helps to limit the amount of dust that can settle on the keyboard, saves battery life and prevents the keyboard from an accidental coffee spill—a leading cause of laptop damage.
6. Laptops can overheat more easily than a desktop computer can. You shouldn't set one on a blanket, pillow or other non-flat surface that could prevent sufficient ventilation.
7. Be careful where you take your computer and set it down. Again, its portability can work against it. You shouldn't take it to the beach and risk getting sand in it. Same with using it on the kitchen counter, where it could drop into a sink or onto the floor. And even if it's NOT plugged in, you shouldn't finish your spreadsheet while relaxing in the bathtub!
8. You should always carry it in a good-quality laptop bag or cushiony case that provides protection against drops and jostles. You should also get into the habit of never putting anything on top of it (newspapers, mail), because if it's on the bottom of a pile, even heavier items—books, backpacks, etc.—could also get piled on.
9. Set up passwords for access to your laptop (for family members who might also use it). Make sure they do not use "password," "ABCD" or other simple passwords any thief could guess, in case it's ever stolen.
10. Open a personal virtual private network (VPN) account and use it as often as you can in airports, hotels and hotspots in coffeehouses—in other words, anytime you're plugged in to free Wi-Fi or strange networks. A VPN reroutes your Internet connection to secure networks, where a hacker cannot steal your data.
