Wake On Lan - Possible Cause of Z Battery Drain

Hi Folks,

I disabled Wake On Lan in my Z590 about 15 hrs ago, shut the computer down, left the battery in, and rebooted a short while ago.

The battery did not drain overnight. This is the first time it hasn't. I've tried it only once, so it's still an experiment.

I was thinking, if you like, you could disable Wake On Lan and post your results in this thread.

For Vista: Start --> Right Click Computer --> Properties --> Device Manager --> Network Adapters.

For XP: Right Click My Computer --> Properties --> Hardware --> Device Manager --> Network Adapters.

We're interested in these: Intel (R) 82567 LM Gigabit Network Connection and Intel (R) Wireless WiFi Link 5100.

Perform this process on first one and then the other: Right Click --> Properties --> Power Management --> Uncheck Allow this device to wake the computer.

Shut Down overnight, and post your results here!

 

I ever took out the battery after it was full charged, then installed the battery back after 6 hours, and found the % dropped to 97%. for 24 hours, the result should be 3% x 4 = 12%.

The result was the same as that if the battery was not taken out, and I started the os after 24 hours, found the % dropped 12%.

so the battery drain is ceaseless regradless whether it was used or not.

 

Is it? Or are you actually measuring the amount of battery drain from booting up the machine? To test this, fully charge the battery, take it out for 12, 18 or 24 hours and take your measurement again. If it is still 3%, all that represents is the boot up drain amount.

I probably will try as you say.
however I do not think a boot up can use up 3%.

 

I await a serious response to this thread with fevered anticipation.

 

I will full charge the battery, and pull it out, leave it alone for 24 hours.

I will post the result here tomorrow.

 

This has nothing to do with the "shut down battery drain".

 

A boot up can use more battery than you think.

 

I just want to make sure whether battery drain problem is just coming from the battery itself. Regardless whether it is used or not, the power is *leaking* ceaselessly. if so, there is no any methods can resolve the problem, including #1 that to disable disabled Wake On Lan or any other things.

battery drain is not unusual for any types batteries, even though you leave them unuse, the battery is still draining. the only difference is that the draining speed is different among the batteries. for sony, probably, its battery is an extreme instance.

 

We need answers, and we need them NOW

 

Thing is, wake on LAN isn't on by default for any of the devices. At least not on my 590. Have you perhaps re-installed Windows?

 

My "Intel (R) 82567 LM Gigabit Network Connection" was set to allow wake ons (factory 32bit vista business install - Z27).

I've switched it off, but I can't be bothered to test

 

I have disabled WOL from the beginning (in September). But loose 7-8% dayly. (Never compared to WOL endbled)

 

Result is NO GO.Problem still there 6%-8% for 12 hours

 

The Problem Remains. Call In The Fbi

 

This sounded good. Too bad it wasn't true.

If your battery really looses 12% charge in 24 hours while it's out of the laptop I think it's defective. Better test it.

 

update!!

the % of charge is dropped 2% to 98% after it was full charged, taken out of z, and left it alone for 24 hours. so, that seems the battery has not big issue? does the problem come from z itself? if so that is even worse.

however, there is little of differece this charge, since I already set it at 50% of charge using the battery care function, it could not be full charged, so I disabled the battery care function in order to allow it to be full charged.

I not sure whether is there any difference due to my changed the setting.

I will try more, to find the difference.

 

I haven't re-installed Windows. My Z590 came with Vista Business.

Sorry folks. Sounds like dissapointing results. I haven't powered mine up for a few days. I'll check it out when I get home. Sunday night, I powered down with 69%.

 

Just checked - mine lost power, too.

I also picked up a Lenovo X301. That was losing power, so I did some research and found out that Wake On Lan was the likely cause.

The instructions I found for disabling WOL cover disabling via Device Manager and BIOS. The Lenovo BIOS allows access to this feature but the Sony does not.

The Lenovo X301 battery retained all of its power. Perhaps if we ever are able to access the feature via Sony's BIOS, we can disable it there, too and solve the problem.
