Windows The past few weeks or so, there's been a lot of interest in a supposed battery status report bug in Windows 7. After installing Windows 7, some users reported seeing "consider replacing your battery"-warnings in systems that appeared to be operating just fine on Windows XP or Vista. After extensive research, Steven Sinofsky has now explained on the Engineering 7 blog that the fault is not with Windows 7 - it really, really is your battery.

So tiresome to see your laptop's battery life slowly degrade over the years. And all of these "breakthroughs in battery technology" that keep popping up in the news never seem to amount to anything. Laptops are still using Li-ion batteries, right?

PS: "the battery was already in need of replacement, but XP nor Vista had the ability to report that to you."
Shouldn't that be "neither XP nor Vista"? http://en.wiktionary.org/wiki/nor#Conjunction

Hi,

Change costs money, which might cut into laptop manufacturer's profit (especially as there's no easy way for consumers to compare the life expectancy of laptop batteries, so improving this life expectancy probably won't result in better sales). Doing nothing means the laptop manufacturers make more cash; either from replacement batteries or people upgrading the entire laptop earlier than they otherwise would.

Eventually, with enough research and technological breakthroughs, I'd expect batteries that die 2 weeks after the warranty expires (but I wouldn't expect longer life)...

Well, there has been lots of significant breakthroughs yes, like the Li-air technology which would both provide longer battery life AND longer discharge time. But you have to remember that even though they've found a way to do such things it takes several years to find a commercially viable way of producing the same effect. In the case of Li-air they have huge hurdles in front of them due to having to find a way to mass-produce the components needed and how to do it cheap.

I'd say that just hang in there; with all the advancements in battery life during the last year it should take 5-10 years before the new technology is finally mass-produced and brought to general populace. But when they finally arrive we'll all be happier.

My battery needs to last long enough to get me from one outlet to another. My laptop is plugged in as often as possible.

PS: "the battery was already in need of replacement, but XP nor Vista had the ability to report that to you." Shouldn't that be "neither XP nor Vista"? http://en.wiktionary.org/wiki/nor#Conjunction

Yes. I've PMd Thom with a pointer to that effect before, but he seems quite content to ignore it. I figured since his English is damn near perfect, he'd be happy to hear about and correct one of his few remaining problems ;)

What!?! And have people mistake him for a dirty American? What are you even saying? ;P

That's actually really bad for the battery because the cells don't complete the charge/recharge cycles. Then when you do suddenly need to start carrying the laptop around, the cells won't "dig deep" and keep going. The circuitry does the wrong thing.

I think this is a side effect of Microsoft's longstanding push for each OEM to write their own "drivers" for simple stupid things. There are motherboards out there that actually report different hardware settings to Windows than "generic Bios" and this is just another one. We've seen hard drive controller have "hidden codes", "soft" sound cards, "soft" modems, and the list goes on. Microsoft finally felt the need to "fix" the bad hardware their older OSes allowed OEMS to hide for years, just like when they finally added a good wireless manager to Vista after the one in XP was a dog and OEMs pre-SP had to roll their own.

My point is that these things SHOULD be open hardware APIs, but their "just a little broken" so you need the "Windows X-version" drivers... that way each OEM can feel special, Microsoft can poke vendors like AMD-Intel and Nvidia-ATI against each other over petty details, instead of how good a computer allows the user to do tasks.

edit: You have to get the joke. Microsoft keeps it's monopoly by being the only player that can sort out all of these little pieces. They pit chip manufacturers, computer makers, software writers, and users against each other so they're so busy "stomping bugs" they can't go anywhere else.
