After fully charging and putting aside one of my laptops for two weeks with the battery installed, I attempted to start the laptop and found the machine completely dead.
At first, I suspected the (new) battery might be faulty, so I recharged to 100 percent, removed the battery and put the laptop aside for two days. If the isolated battery held its original 100 percent charge, or even a few points lower, I could not conclude the battery was faulty.
On checking available charge after two days by reinstalling the battery and booting with the power supply, I found the battery at nearly 100 percent.
Next, with the battery still at 100 percent and installed, I again put the laptop aside for two days, and after checking, found the battery had lost significant charge-- down to 75 percent.
Here, I reviewed by findings. Whenever I switch off the laptop with a normal, complete shutdown, with no LEDs of any kind displayed afterward, and with no hard drive or fan noises, my laptop battery still "bleeds" charge at a significant rate. Rather than presume this is normal, I have checked my other laptops and found the same charge decay effect. The charge drops by as much as 10 percent daily.
All this may be industry-normal. For example, cellphone batteries eventually lose charge, especially when the cellphone is actually still ON while on standby status But if the laptop were fully shut down with battery installed, and its status confirmed (no LEDs or whirring fans, anywhere), why should the laptop battery bleed voltage?
