Hibernate/Shutdown Question

My laptop is XPS M1530
I just owned it for about a month.

Intel T9300
4GB RAM
200GB 7200 Harddrive
GeForce 8600M GT 256MB
56 WHr battery
Windows Vista Ultimate
What I want to ask:
1. Last week, I use my battery which was FULLY CHARGED. I plan to store my battery and not use it for a long time so I use it until it remain 40% only.
Then I shut it down but I chose the POWER symbol NOT the ShutDown menu. I thought the difference was the POWER symbol will go into hybernation?
Then I take off my battery and the next day I use the AC adapter, and I thought my laptop was activated from hybernation because it displays "Windows is resuming..."
When I got into desktop, there was a message on the tray remind me that the battery is LOW. I was confused because I use the AC adapter only that time, is it how hybernate works?
it did not save the Windows and programs only? but including the power management like battery level, etc.?
Did what I do affecting the battery or the laptop? I mean does my laptop or my battery is alright?

2. I read in a forum that if I plan not to use battery for a long time, it is recommended to charge it for about 40% only. Do these 2 condition different?
A. I have my battery 100% charged and I use it until it remains 40%.
B. My battery is almost empty and I charge it until it reach 40%.
If they are different, which one is correct?

Thank you very much.

 

The computer should use no more power when hibernating than when it is off completely: The memory contents are written to the hard disk and then the computer is shut down.

I wonder if your problem is caused by Vista's hybrid sleep option which combines both suspend and hibernation and only changes to real hibernation when the battery is low. Go into the advanced power settings, expand the sleep menu and make sure that Use hybrid sleep is set to off. (Maybe you could leave it on for plugged in, but I'm not sure what happens if you unplug the mains power after hibernating the computer).

As for the battery management, the working life depends on the number of charge cycles (I've seen numbers between 300 and 1000). Most notebooks don't recharge the battery when there is only a small drop in charge (typical recharge trigger points are 90%, 95% and 98%). Sony offer a utility with some of their notebooks where you can change the recharge trigger setting to 50% or 80%. However, this issue is academic if you don't have the ability to change the setting for recharging.

But does my laptop and battery still ok?

 

Everything is fine including your battery! Trust me some of my best friends are battery's. My mother was a battery. It does not matter if you charge up or charge down to get to the 40% to 50% level for storage.

 

Batteries are easily replaceable. And they were invented so that laptops could be mobile. If you're getting a laptop that will sit 90% of the time on a desk, it will be better to get a desktop and a small laptop.

 

Is it ok with my laptop or battery if I plug off the battery as soon as AFTER I turned my laptop off?

Thank you.

 

I've experienced this issue myself where I'm on battery power, put it into hibernation and then start-up again with the ac adapter but with the battery out. Hibernation saves everything as exactly the way it was before, so when I hibernated on battery power it shut off thinking that it was still running off battery. When you start-up again with the adapter but with the battery out, it can't detect a battery but still thinks there's one inside your laptop, thus it gives you a low battery 0% warning.

 

Did it cause any problem with your laptop? Does something like this normal?

 

Not that I'm aware of, it just a bit glitchy but would be fixed by a simple restart. Otherwise, it won't harm your battery or anything like that.
