I'm a user from Changchun, Jilin Province. I requested a manual service through “HP Service” WeChat client on February 26th. The reason is that my newly purchased laptop's battery drains at a very high rate even when in standby mode, which has adversely affected the normal use. "Xiaohui 260" was the technical engineer who received me but I was amazed by how he handled the issue.
他表示没必要查看我提供的、反映电量下降情况的视频，同时在没有得到"HP Support Assistant"的电池检测结果情况下，即告知我电脑不存在任何问题，无需继续咨询维修。我无法想象惠普的售后服务是以这样一种方式进行的——既不核实问题原因，也不需要任何检测结果，而是直接告知用户不存在任何故障，而后置之不理。
He said that the video I provided showing the draining battery doesn't need to be evaluated. Even without seeing the battery test result from "HP Support Assistant", he told me there was nothing wrong with the laptop and no need for further consulting. It is impossible to believe HP's after-sales service being conducted in such a way that it doesn't look into the cause of the problem, doesn't request any test results, but instead arbitrarily informs the user that the problem doesn't exist and then ignores it.
Even more surprising was the fact that he said "it is normal that the battery is reduced by 3% in just several minutes without running any additional applications''. I wonder whether this absurd explanation represents HP's official policy on product quality.
It is disappointing that HP personnel refuse to provide after-sales service in such a irresponsible manner. I am writing this letter so I can bring this complaint to your attention.
Enclosed is the corresponding screenshot from WeChat. Additional information could be provided if needed.
Details: The related product is HP ProBook 450 G8, serial number **********, which was activated for the first time on February 22, 2022. The main problem: No application other than the system built-in has been installed, and the operating temperature/humidity is about 20°C/20%. In standby mode without any extra apps running, the battery drains rapidly. It prevents normal mobile usage. Typical example: 3% battery drain in 7 minutes in standby without running any additional applications.
