The official VAIO Z battery drain thread

[aamsel]

I am using a new Z570.

With the battery charged to 100% and then shutdown and disconnected from the a/c adapter, it loses 16% of its charge when checked in exactly 2 days.

Wouldn't you consider this to be excessive battery drain?

I did not test by removing the battery from the laptop, since I shouldn't have to do that.

are u sure its battery drain? couldn't it be power required to "turn on" the laptop?

The Z was turned on ONCE, to check the battery at 2 days, no other time.
It does not take 16 percent, or 4 percent of the total battery life to turn on any notebook one time.

There is another long thread regarding this topic. People have tried all kinds of things, and still loose power. They experimented different shutdown procedures, and there is no conclusive evidence of what is causing it. If you remove the battery at night, and plug it in again in the morning, it will be 100%less the startup usage. Really strange. Maybe the instant start, maybe the wireless radios are still on even the computer is shut down.

Same issue here with the Z590. I hope this thread gets more attention this time around. To pay such a higher premium for the Z's portability (which implies battery life), it's a shame more people don't notice this problem.

Good thoughts, but the wireless radios are not on with the unit shut down.

I have an RMA for a refund for mine as defective due to this and another issue. I have the low-res version, and find the backlighting to be uneven, and putting up a pure white screen gives nothing close to white, more of a mottled grey.

But, I would keep it with the screen defect, but 16% battery loss in 2 days is just too much IMHO.

I hate the light leakage. I had a bit on the TZ, but I do not have any on my desktop monitor (Dell 2405), and very little on my 6 year old Dell laptop. I'll look at the screen first the next time I buy a vaio (either z or the new tz).

same problem on the SR
Battery drain problem on new Vaio SR?

[hamud]

same problem here !! I shut down my laptop at 50 % and after 9 hours it was 29 % ?????????

[newtothis]

wow, 21% in 9 hours... and I thought I had it bad.

I'm losing about 10% in 8 hours here.
