We use a colorimeter to measure screen brightness and color gamut while other instruments help us determine a laptop’s key travel and ambient heat. See this page on How We Test Laptops for more details on our benchmarking procedures.You can spend a lot of time delving into specs, but here are the key components to think about. If you just want really good mainstream performance, go for a Core i5 CPU, 8GB of RAM, a 256GB SSD and a 1080p screen.Screen Resolution: Unfortunately, 66 percent of consumer laptops and 51 percent of business systems have low-res screens. If at all possible, get a display with a 1920 x 1080 (aka 1080p, or full HD) or higher resolution.
CPU: An Intel Core i5 provides good mainstream performance. Some budget systems will come with Core i3, Celeron or Pentium CPUs, which are good for basic tasks, but not heavy multitasking. Get a Core i7 or a quad core processor (serial number ends in HQ or HK) for gaming or high-end productivity tasks such as video editing and 3D modeling.
RAM: 8GB is ideal for most users. 4GB is acceptable for budget systems. Secondary laptops and Chromebooks may have less.

Storage: Unless you’re a gamer or a power user, 256GB of internal storage is probably enough. If at all possible, get an SSD (solid-state drive) rather than a hard drive, because it’s going to make your computer a lot faster.
Graphics Chip: Gamers and creative professionals need to do some research and figure out which discrete GPU is good enough to run their favorite software. Everyone else will be happy with the built-in Intel HD Graphics that come with the CPU.
I come from the time where we carried spare laptop batteries with us, and they were instantly swappable. I’d press a small button on the battery to light up some green LEDs to see how much juice was left in a spare. Those days are gone. We have now entered a dark age where batteries are sealed behind obscure pentalobe screws. After 7 years my treasured 11" Air was unable to hold a charge for longer than 75 minutes or so. I was fucked and going to have to open that case.

I love that little 11" laptop. It is the device I carry for creative writing. Small enough to not be a bother, but functional enough computer to do anything I need in a pinch. I did not want to lose this laptop, but the short battery life was killing me. Most of the coffee shops and places I like to work no longer want to offer power outlets to folks drinking one cup of black coffee for 2 hours.I tried cycling the battery to restore some lost capacity. It did not help. I looked at the iPad Pro with a keyboard. I even looked at the Surface Pro. Then I researched batteries and the replacement looked like it should be no problem.I searched the internet’s latest iteration of forums, Reddit and Youtube, for info on folks who’d replaced this model battery. I read a lot of Amazon reviews. The size of the replacement battery was supposedly a problem in varying degrees with all models, even Apple sourced batteries. The Temark I chose seemed to have a high probability of going in without a problem.

I used the included screwdrivers to remove the tiny, cruelly chosen screws. I kept the ones from the backplate separate from the battery screws, even tho they are different colors and sizes. When the backplate came off I saw that my battery had broken around one of the screws, damage from an apparent fall. I’d dented the case a bit too — but the laptop never showed an issue. There were splintered bits of battery plastic all over. When I removed the battery, I noticed a thin metal bar had come loose in the area of the trackpad. It had been held in place by the battery pressure, I guessed, and needed replacement.I looked at images of trackpads for my model Air and saw that the bar appeared to sit across the bottom of the trackpad, in-between it and the battery. I felt some residual sticky adhesive where it appeared to go, and the bar stuck right back there. I put everything back together, feeling like I was going to have to take all those screws out again, and should have tried powering up before I had screwed them all in.

Everything works perfectly here, now. No, really. No problems. When I am done working on the blog this am, I’ll take my Air to a coffee shop and work on a short story. It now gets 4-5 hrs of power. More than when it was new.If you own a PC there’s a very good chance it’s a lightweight and portable laptop, rather than a big and bulky desktop. Those rectangular boxes that are tethered to your desk have been declining in popularity, with laptops now far outstripping them when it comes to sales.Thanks to an almost constant stream of innovations, the humble laptop has become slimmer and lighter than ever before, while the hardware inside them has become ever-more powerful, while batteries are lasting longer.Creating a powerful and portable computer is no mean feat, and here we look back at some of the pivotal moments in the history of laptop development, and examine how early machines influenced the laptops of today.

Many people consider the Osborne 1 to be the granddaddy of laptops. Released by Osborne Computer in 1981, the Osborne 1 had a five-inch screen, two floppy drives, a modem, battery pack and a keyboard that was built into the lid.Although it was big and bulky (it weighed 11kg, which is just over the combined weight of five MacBook Pros), this early computer still has some recognizable laptop features. Sadly, it wasn’t a hit, but it showed the potential of a portable personal computer – for the first time, people were able to carry their computer with them and work on them when traveling.The first portable laptop that really looked like a laptop was the Grid Compass 1101, which was released in 1983. It featured the clamshell design, with the screen able to be folded up against the keyboard when closed. This remarkable innovation meant that the Grid Compass 1101 could be more easily carried around, while the screen and keyboard were kept protected.

It was such a successful and influential design that it’s endured to this day, and while the Grid Compass 1101 itself wasn’t a huge success due to its high price of around $10,000 (around $25,000 / £20,000 / AU$35,000 in today’s money), the patents on many of its innovations earned GRID Systems Corp a lot of money.Up until this point, early laptops were sometimes referred to as ‘luggables’, due to the fact that while they were more portable than a regular PC, they were still large and bulky, and not easily carried.However, in 1989 the Compaq LTE and LTE 286 were released, and they’re generally regarded as the first notebook PCs, as they were around the size of a paper notebook. These smaller laptops were easier to carry around, making them more popular with people who travelled a lot.

They were also two of the first laptops to include a built-in hard drive and floppy disk drive, making them even more versatile. The hard drive in the Compaq LTE offered 20MB of storage space, which was doubled for the Compaq LTE 286.1989 also saw Apple release its first laptop device, and while it wasn’t as small or as easy to carry as the Compaq LTE (it was still considered a ‘luggable’ device), it offered very good battery life and decent screen – something modern MacBooks are still renowned for.Due to its size and weight it wasn’t a popular device, but it did spur on competitors to release Mac-compatible laptops that were more portable – these days it’s strange to think of any other company other than Apple building Mac hardware.In 1991, Apple released a series of PowerBook laptops – the PowerBook 100, PowerBook 140 and PowerBook 170 – which were far more successful than the company’s previous attempts at creating a portable PC, and they ushered in a number of revolutionary features that have become staples of modern laptop design.
