问题

超级用户读者Eman Slitheran想知道是购买单键还是更换整个键盘更好：

The keyboard on my Asus ROG G73JH-A1 laptop was recently damaged with several of the keys having been ripped off. I would like to know which repair option is better:

• Purchasing single keys online to replace the ones missing on my laptop’s keyboard
• Replacing the entire keyboard

是购买单键还是更换整个键盘更好？

答案

超级用户贡献者JakeGould为我们提供了答案：

In broad/general terms, the answer depends on how common your keyboard is, how much you are “married” to it, and whether you are 100 percent positive that it is a simple case where you just need to replace the ripped off key caps.

For example, this website sells single keyboard keys for an average cost of around $5 each, which seems like a decent deal at first. But just doing a casual check shows that getting three replacement keys for a MacBook Air (MD711LL/A) keyboard would run approximately $27 without shipping included.

But then a quick look on eBay for a full replacement keyboard for a MacBook Air (MD711LL/A) shows that there are whole keyboards available with free shipping that are much cheaper than buying a handful of single keys.

In the case of your specific laptop model, an Asus ROG G73JH-A1, a quick search on eBay (using Asus G73 as the search term) shows that you can purchase a complete, brand new replacement keyboard for approximately $8 and up with free shipping. So in my opinion, a full replacement keyboard is your best bet.

In general, even without knowing what make/model of laptop you have, I believe that purchasing a full replacement keyboard will always cost less than purchasing individual keys. The nature of the way many keyboards are manufactured these days—**all components, very little standardization, and even variance in size/shape/layout within a model line—makes them essentially disposable commodity components.

A full keyboard replacement is a common commodity that can often be purchased for less than individual keys. Changing individual keys is an anachroni** at best nowadays and only seems to happen when one really wants to customize their laptop’s look or they are using editing tools with elaborate key combos that require a custom set of key caps.
