Home working leads to more laptops
They seem quite confident about home working leading to increased sales of machines. Ignoring for the moment how home working will catch on, I'm not certain about the other chunk of that. Sure, some companies will have to change out computers for home workers, because they did desktops and would have to switch to laptops. But if a worker already has a laptop from their employer, they don't need to replace it. Also, I'm guessing most businesses that will be switching to home work have already done so, meaning the first round of obligatory laptop purchases probably started two months ago and is ongoing. That implies that this quarter's sales may be somewhat high, but that it probably won't be a longterm trend because a lot of other companies won't be buying new machines or replacements until the ones they're using more actively are much older.
Maybe Lenovo was hoping for more personal purchases because children have been doing online schooling while their parents use existing machines, but those purchases have also likely been made and online schooling is not going to continue as long as home working. I think their optimism may be premature and they'd better make quite a bit of progress in this quarter if they hope to hit that growth target.
