Sleep battery drain

I have a 6-cell battery with 12% wear according to HWMonitor. Laptop specs in signature. During sleep, my laptop loses about 1.9% charge/hour ... Is this normal? It never wakes up to do anything and there is nothing plugged into its powered eSATA/USB port.

 

I think it just depends on the laptop/components/BIOS/sleep state.

My Vaio needs 5% per hour on Standby (that's sleep).

Unless you hibernate - then its unusual.

 

Sleep is not no power. It's very low power. Do not ever put your laptop in a bag while it is sleeping... it still gets hot. Sleep is for overnight or while the machine is sitting unused on a desk, it's just a low-power state so that it can wake back up quickly.

 

Use hibernate instead. Sleep uses significantly more power and is just marginally faster than hibernate. Although laptops are a lot better at both for energy conservation than almost any desktop.

Does it ever. A short walk across campus taught me that. I thought I was having some type of heat flash or something until I realized it was the notebook in my backpack.

 

That shouldn't happen.

I've carried my laptop in sleep mode over a period of close to two years now - and my old one too.

Never got hot - its not supposed to while sleeping.

If it did it woke up.

 

Yeah, my laptop fan is off when it's sleeping. Never gets hot. (Quite a different story when it's awake though..)

 

My laptop's allright when sleeping.. doesn't get hot.. special modded Dv5t only get hot in gaming

 

That is a possibility. But since I'm not a fan of carrying my notebook around in any state other than off, I never took the time to diagnose it.

 

well... on standby its pretty much off - only the ram is held "on" and maybe some other non heat producing components.

The CPU and GPU are definitely both Off - as is the HDD.

 

Oh OK. When I put my laptop to sleep it's super cool ... No heat lol for some reason hmm. I disabled hibernate since I wanted my 4 GB of space or so and I rarely use it. THanks for clearing this up though!

 

Sleep should not generate heat, as it's only the RAM being powered as far a I know. I know I had to tell my Toshiba to hibernate when I closed the lid, though, otherwise it seemed to wake up randomly, especially if it was sleeping and I unplugged it from its charger, like when I took it to class.

 

I've never had this problem with any laptop I have used. Like someone said, if it wakes up for some reason then I could see it but I turn off wireless when I put laptops to sleep.
