Previously, Apple has been involved in a lawsuit over the use of disc keyboard in MacBook. < / P > < p > many users complained about the so-called "stage lighting" problem with apple MacBook Pro screens in 2016 and later versions, that is, the backlight at the bottom of the screen presents a stage lighting effect. The root cause of this problem is that Apple uses a thin and fragile flexible cable in MacBook Pro to make < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E6%98%BE%E7%A4%BA%E5%99%A8 "> the monitor < / a > is connected to the controller board, and with the screen opening and closing for many times, this fragile flexible cable will be damaged, resulting in the above problems. < / P > < p > because it takes a long time to open and close for many times to find the problem, the equipment purchased by users often has exceeded the warranty period. In addition, because the damaged cable is integrated into the screen, it is not possible to simply replace the $6 cable, but the entire screen must be replaced, for which the maintenance cost is often as high as $600. < / P > < p > Apple initially refused to guarantee the affected machines until a few months after 15000 users signed a petition and put pressure on the media to create a program called "screen backlight service" to help solve the problem of the 13 inch MacBook Pro, excluding the 15 inch model. < / P > < p > judge Davila's ruling did narrow the scope of the proceedings, but allowed them to continue. The plaintiffs claimed that Apple continued to sell the defective 15 inch MacBook Pro without warning consumers and filed fraud charges against the company. Davila said that consumers' complaints about Apple's pre release testing of the new machine fully show that apple is aware of screen defects. < / P > < p > the lawsuits also allege that Apple has deleted official posts from the apple support community complaining about the issue. Apple does not seem to deny this, but argues that it has nothing to do with the case. The judge disagreed, saying it could serve as further evidence that Apple knew the design was flawed. < / P > < p > unlike the disc keyboard lawsuit, the MacBook Pro screen issue has not yet become a court certified class action, but now nine plaintiffs have filed their respective indictments. The judge is inviting them to submit a revised indictment to decide whether to merge into a class action. (small) < / P > < p >
