back to article Windows 7 upgrades Vista laptops to lower battery life

Laptop owners upgrading their Windows XP and Windows Vista machines to Windows 7 are complaining that Microsoft's new OS has severely reduced their available battery life. One user tells The Reg that after upgrading his circa 2007 HP notebook from Vista to Windows 7, the machine's battery life dropped from two hours to a half …

Windows has always been a battery hog

Look at the new Smartbooks getting 10 hours + battery usage on each charge.

Not really...

Windows has not always been a battery hog. My trusted Eee PC 1000 lasted 8+ hours on Windows XP, And Windows 7 has stricken it down to 4,5, or 6 at a push.

Well...

"But the company also says that in some cases, the new tool may be working properly."

It's good to see that Microsoft's QA department is still doing its stuff in the way that we've come to expect of them.

Excellent?

Quote: "I was having excellent battery life until I installed the RTM of Windows 7 - all RC and beta builds that I installed I had nearly three hours of battery."

Nearly three whole hours is excellent? Wow! That's a bizzare assessment of what constitutes excellent imo.

depends

depends on the equipment in question, if it's some 17" desktop replacement SLI gaming laptop then 3 hours isn't bad at all!

3 hours.

It's relative. If you have a road-warrior desktop replacement which is over three years old, three hours would be excellent! If you have a current netbook with all of the power saving features enabled, it's not. Remember that the eeePC 701 (the original 4GB SSD one) was only quoted as having about 3.5 hours of battery life with the high capacity battery, and that was only three and a bit years ago!

My trusty thinkpad T30, which is about 6 years old, gets about 1hr 20min. When it was new, the handbook said that it should have been 3-3.5 hours. If I still got 3 hours I would regard it as excellent, but as I only use it on batteries infrequently (part of the problem), it's no issue (and being a Thinkpad, I could always get a Chinese replacement battery for about 30 quid if it was).

It happens....

New software on older hardware brings this stuff up sometimes. Didnt happen to my tosh laptop which continued as it had under vista. It is just a tweak after all!

Wala?

Someone doesn't know their French.

So there's a battery alerter in Windows that drains the battery? Hmmm, what does that remind me of... Oh yeah! The "feature" in Windows Mobile that turns on the screen when your battery is dying, then keeps the screen on to make sure it dies as quickly as possible.

Not my Experience

I am getting better battery life out of my Acer laptop under Windows 7 than I did with XP or Vista.

It's three years old and still on the original battery. Good for nearly 3 hours with wifi connected.

I was going to upgrade to a new machine this month, but Windows 7 has made the thing a whole lot snappier and good for another year.

I'm not a pedant...

...but I do (occasionally) look like one. And "Wala!" never fails to get my vibrating, arse-faced robo-goat. I expect "Tada!" sounds a bit unsophisticated. And suspiciously foreign, perhaps. Not that I'm lobbying for "Tada!".

Wala!

Where's the "Wala!" icon? And some music to put it to? (I suggest a minim at the very least. Though I'd want a crotchet for this rant).

WTF?

Why the cock is the OS forcing a shutdown if the juice is still flowing? This isn't some server or mission critical set-up (which Windows is not certified for anyway); it's a freakin' laptop! Gone are the days when a sudden power loss would knacker a HDD...hello...auto-park!

If someone is dumb enough to run their battery into the ground and cause a sudden power loss and thus losing their work....that's their chuffin' look-out.

There's dumb, there's dumber and even dumberer.

Then there's your average Windows user.

Why the cock is the OS forcing a shutdown if the juice is still flowing?

Because it'd be a bit tricky to force a shutdown once the juice has stopped flowing, wouldn't it... In this context, "shutdown" should be interpreted as "closing down the OS in a controlled way so as to avoid any loss of data or filesystem integrity, allowing the system to restart without error once power is restored".

Take it from someone with personal experience of seeing an XP desktop PC knocked out by a power cut, which then blue screened on every attempt to restart it once power was restored, resisting every attempt to repair whatever damage had been done to the filesystem, and ending up requiring a clean reinstallation of XP and all third-party apps - given the choice of letting the OS enforce a controlled shutdown when it thinks the battery level is getting too low for comfort, or risking losing more than just the last few minutes of unsaved data when the system shuts down without warning, I'll happily leave the OS in charge here.

A reinstall?

Let's face it, back in the day Win9x would fire off ScanDisk on a restart after a power outage. XP is total shit in that not only is ScanDisk severely broken (guys, learn the command line and use ChkDsk, it actually notices things ScanDisk ignored) but when the system loses power unexpectedly during a disc write, it will boot as far as loading the NTFS driver, then it will bluescreen with UNMOUNTABLE_BOOT_VOLUME. Yeah, like the one it is actually booting FROM up until that point? It's a corrupted map. It's the time when ChkDsk SHOULD be invoked, automatically, if XP had any clue whatsoever.

But to reinstall XP and all the stuff? Aïe! No!

Google for "Hirren's Boot CD". Boot off the CD. Select to boot DOS. Choose the one with NTFS support. It will ask if you want to run its own ChkDsk. Let it fly. It will find and fix the error. Shut down, restart. Your file might be damaged but XP will be fine.

Mainly Toshiba hardware here, of all flavours, and there doesn't appear to have been any changes or problems with battery life so far.

I used to get 2.5hrs - 3hrs out of my admittedly aging HP NX6110, however W7 RC1 has never let me get anywhere near that, I chalked it up to it's age, but maybe not so...

My first impression

I'm voting for deliberate malapropism too simply because of all the grammar Nazis who can't take a joke. Whoever thought that a Windows user could have had a sense of humour?

not true..

My HP has suffered no such battery fail. In fact I find the power actually lasts longer due to several bugs being ironed out with the windows CPU usage controls.

Oh, certainly

Apart from anything else, a Mac would tell YOU to consider replacing your battery. It would tell you to consider paying Apple to replace your battery.

"Because the software and hardware are designed to work properly together."

Because the software is only designed to work with a very limited set of hardware.

Say! It will always be so?

The trouble is that software solutions will always require more energy than custom hardware solutions and the way windows is presently designed really caters for mains powered desktop designs.

Windows Genuine Advantage got many people phing up Microsoft with their credit card to pay them £90.

This new microsoft feature is working correctly and will sell a great number of replacement batterys.

And what of the FACT that there are many people complaining about battery life ? Or are you the kind of person who, if this article had not been posted, would complain about the Reg ignoring battery issues with MS Vista SP2, aka Windows 7 ?

Define "news"

Windows 7 RTM has been available for almost 6 months now (since August 6th 2009 from Technet) - and of the millions of people who've installed it, a few random people have encountered problems?

And this is news?

By the way, Vista SP2 is called Vista SP2. It was released on May 26, 2009. Not that abject ignorance about the topic in hand ever stopped anyone else posting a comment to ElReg.

7 + Battery..

As my 'Big Netty' 12" Packard Bell ( dual core 1.8ghz) was 1hr 45 min ish on XP, now 1hr 30min or so under 7 Ultimate (64 bit) no big hit particulary, havent tried turning of the Aero twiddliness yet tho.

Bluetooth stack needs fettling up though.....

Could be different manufacturers have different battery sensing arrangements and Windows shiftyware is making assumptions on the basis that the firmyware is all reporting the 'same' numbers..... when it isn't.

A lot of commenters are missing the point

Windows 7 is not burning more juice, it is incorrectly saying that the battery is flat when it is not.

My Fujitsu tablet started doing exactly this when I upgraded to Windows 7. Runs for ten minutes or so and then tells me the battery is critically low. Boot it into Ubuntu and I've got 3 hours left.

Hope they fix it or guess which OS I will be booting into by default.
