As such, the cheapest and most secure way of protecting yourself during a lightning storm is to turn off and unplug your equipment.

Laptop Overheats in a Confined Space

Some laptops can get hot at the best of times, let alone when in a confined space. Theoretically, a thermal shutdown circuit should shut everything down if the system is becoming dangerously hot, but it’s never safe to rely on that. If you finish with your laptop, put it to sleep and then leave it somewhere enclosed (like in a laptop bag), it might be time to reconsider.

Dropping Your Hard Drive

Read More , which have static components, hard drives are mechanical devices that have a head that floats above a spinning platter in order to read and write data. Although the platter is coated with a non-electrostatic lubricant that helps protect it from minor collisions, if it has serious impact then it’s going to scratch and damage the platter.

If the platter gets damaged in any way, there’ll be a major risk of data loss. It’s where your data is kept and if it gets damaged then there’s no way that the head can access it. If you consider that dust landing on the platter can potentially cause harm, which is why you should never open up your drive in anywhere but a specialised clean room, imagine what would happen if the head collides with it.

As such, you need to be ultra careful not to drop a hard drive, especially if it’s an external one that’s constantly on the move. It might sound obvious, but although something like a smartphone can survive a drop, the chances are less likely on a hard drive.

    I like the comment about UPS. They are great at protecting from low voltage or power loss, but their surge protection is minimal. Always use a good quality surge protector and plug the UPS into that and the computer into the UPS.

    Search for a website Do NOT type it in the address bar, misspellings or typos can lead to you to a lot of bad websites, especially when using Internet Explorer. Most popular sites have a proper redirect, if for example you type gooogle.com or anazon.com they'll direct you to there proper site.

      Make sure that the link goes to the proper site. It is not uncommon for a frequent typo to have a website at that address that will take you somewhere else, usually loaded with links to related sites but sprinkled with lots of malware. I think it is actually safer to type the actual address wanted. If you've been there before and it is still in the browser history, most browsers will show you an autocomplete selection; or use your browsers bookmarks to access frequently used sites.

    Don't bother with surge protectors, invest a bit more and get an Uninterruptible Power Supply (UPS). Power goes into a (replaceable) battery and the computer draws its power from the battery. This prevents surges and also brownouts (insufficient voltage) from affecting the computer. You can also use the battery to charge your electronics during a blackout. I'd also recommend them for your big screen TVs.
