What is the best laptop brand for business use?

For business computing, you need a laptop that comes with pro-grade security features. I would recommend an HP business laptop – either one of the HP ProBooks or Zbooks, depending on your required computing power. HP business books come with BIOS protection to protect your PC from many modern-day malware programs. They can reduce the screen viewing angle to the extent that nobody can see anything on your screen even from the sides. This can be very handy when you’re working in a public place. They also have webcam shutter protection, much better battery life, fast charging and a durable body. The high-end ones come with Magnesium Alloy body, which is the same material used for building aircraft. They have HP SureSense technology that prevents security threats before they happen. The notebooks have passed MIL-STD 810 G 19 tests, making them durable for rough conditions. Their prices start from around 60k.
If you are a power business user, then a mobile workstation-class laptop would be a better fit for you. For instance.
