我正在使用 HP 15 R 074TU 笔记本电脑。
笔记本电脑无法持续充电，充电每隔 1 分钟就会断开一次，然后再连接一分钟。
如果我取出电池，我就能毫无问题地使用它。
这是电池问题吗？我应该更换电池吗？
我需要检查电池和如何在 12.04 上校准笔记本电脑电池说一下如何检查。
我做到了
sudo apt install power-calibrate
进而
power-calibrate -r
我不明白从这里该判断什么。
还有其他方法可以校准电池吗？
跑步
power-calibrate -r
说了以下内容
praphulla@praphulla:~$ power-calibrate -r
power-calibrate: option requires an argument -- 'r'
power-calibrate, version 0.01.21
usage: power-calibrate [options]
-d secs specify delay before starting
-h show help
-n cpus specify number of CPUs to exercise
-o file output results into YAML formatted file
-p show progress
-r secs specify run duration in seconds of each test cycle
-R use Intel RAPL per CPU package data to measure Watts
-s num number of samples (tests) per CPU for CPU calibration
Example: power-calibrate -R -r 20 -d 5 -s 21 -n 0 -p
praphulla@praphulla:~$ sudo apt install power-calibrate
