battery drains when noteboob on sleep

Hi.
I've got Portege R700-173 for a few days.

I have a strange problem, my battery drains even if my notebook is in sleep mode.
sleep&charge disabled (on application and BIOS), wake on lan disabled too. my battery drains quickly on sleep. looses >20% in 9 hours !

Now, my battery is 'empty' (3% shows Win7pro64 and BatteryMon) for 60 minutes but notebook still works. Is my software working correctly? maybe it needs some kind of calibration ?

 

Sleep? I don't get it sleep doesnt shut the notebook all the way off, it does power down the hard drive. But the ram and alot of the motherboard stays energized. Thats how sleep has worked on laptops and desktops for years, i want to say forever lol.

Hibernate is a different story, Hibernate goes to the same level of power as a notebook when off.

20% in 9 hours on sleep, wouldnt call it abnormal. As far as the later of problems, cant help you there.

 

I know that notebook takes power on sleep, but I always though that this power is minimal (just to refresh RAM content). I'll use hiberanate then.

Now i have another strange problem, my Win7pro64 showed 3% for ~2.5 hours (1822 / 60087mWh BatteryMon showed).
notebook still worked (without utilization, it just stands next to me with LCD turned on all the time). Is it normal ??

 

I am not sure what the drain on your notebook is supposed to be but what you told me did not sound bad at all.

No thats not normal at all and I am sure it has an explanation. I am hesitant to offer one but from time to time li-ion can suffer from a fake memory effect. Though if this is the case the laptop usually will cut off because of readings its not always the case. You can try doing one full drain and one full charge. But I wouldnt do this too often as Li-Ion doesnt like this. But it does work well for resetting the battery reading.

 

Could it be because of the Sleep & Charge feature? Disable it or uninstall it and see if that helps.

 

hi! thanks for reply.

I know how li-xx batteries work.
and i know that i shouldn't discharge cell below 3V, but here, in notebook battery, electronics control whole process, so i suppose that even by discharging battery to 0-1%, electronics don't allow to discharge cells below 3V (because it would damage them).
today was the second full charge and discharge, I will try to monitor battery on different OS (maybe some linux live cd), but i think that it's not OS fault as OS only reads battery status from BIOS.
