x62果然是高分屏耗电太厉害了。

把屏幕调整到最低亮度，（其实如果是LED的话最低亮度完全不会影响使用，因为已经够亮了。）在节能模式下，四芯平底电池可以至少超过3个小时。（x62在节能模式下干一般工作，比如浏览网页、文档及看普通视频的话也还是很流畅的。）所以如果解决这个高分屏的耗电问题，x62的续航还是没有问题的。

嗯  看个人使用了！

这个无解，老屏幕的功耗只能这样，不止是背光耗电，本身显示也耗电

Battery Life
The idle draw dropped to 5.5 when brightness was lowered to 25 percent. The inefficiency of the old CCFL backlight is seen in our Reader test, where the laptop is put in airplane mode with minimum brightness: in this mode, the X62 (with its tiny 32WHr generic battery) lasted 351 minutes. In comparison, it only lasted about 130 minutes in the browsing test and 55 minutes when placed under full load. Upgrading to an LED backlight should make the X62 far more power efficient than with the stock backlight, but either way we recommend purchasing the larger 75WHr battery for this device.
