From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I've never heard or seen this. Mine has it setup like that to the dock - is there anywhere I can read about this issue? Generally my hardware from Lenovo has been amazing and well supported.
For context, 3 years ago I worked at a company that bought 20 new Lenovo IdeaPads all equipped with i7 CPUs and 32GB of RAM. After 6 months only 3 or 4 survived. All of them had that shielding issue, others started to fail randomly like microphones not working, failing USB ports , screen glitching out or other issues. One of them even broke by itself during a firmware upgrade. We ended up going back to HP because, at least, they're reliable.
I'm always surprised when people buy the non-thinkpads for work, and then wonder why the break, as they are home use at best. The ideapad and their other line are not commercial grade, definitely avoid. But the ThinkPads are in my experience the best, most rugged made systems on the market
Well hardware suppliers still sell IdeaPads to companies. But you see them small things... that lack of proper EF shielding doesn't happen in HP consumer lines.
Regardless, if you're buying the cheapest computer, you're going to get corners cut. I've had my share of HP shortcuts even in their elite book lines, used to buy 150-200 a year for work. They were ok, but the lower models were terrible. This em shielding thing seems weird to me, you're saying the cables aren't shielded on their own and interfere with computing equipment: that doesn't have special shielding? I've had my laptop's open, never seen any shielding from the outside... Just heat shielding from itself really but maybe it's delicate and tiny?
When I talked about EM shielding I wasn't strictly talking about shielding metal plates inside your computer. Although certain components might be shielded with metallic plates most components are tested for EM compatibility with other devices (they have to by law) and there are different possible levels of EM interference resistance and hardening. What I've noticed with cheap brands is that their components usually tend to be cheaply built and very susceptible to EM interferences. This doesn't happen in brands like HP or Asus, they take a lot of attention to that detail. And yes, that typical copper heat shielding sometimes doubles as EM shielding.
