Either way, this fixed my issue and I could then use it for 2 hours, it told me two hours and no longer died at 30 minutes. In that case, you may benefit from a recalibration. I'm not giving them my money until they fix this. I disabled power management on one and I get about 45 minutes of life while the amber light blinks at me. I actually bought two new batteries to prove that it is not a hardware problem. . The battery chip is probably not fried because the laptop is able to sense battery level fine while Windows 7 cannot.
Wasted money considering I clearly cant use my windows 7 on the machine anyway unless I don't want to use a battery. Video of the Day Step Click the check-box beside the power plan option that best matches your current activities. I totally agree with Btstech, Microsoft has a problem! If you have to manually recalibrate a battery, the procedure is pretty straight-forward: Step 1: Charge your battery to 100% or to whatever max percentage it can reach and leave it there for about 2 hours to cool down. If what you are saying is true, then we simply have a different problem: Windows 7 provides dramatically worse battery life than any of the operating systems that preceded it. Is the battery eeprom affected by the upgrade? The battery lasted 2 hours and 50 minutes, before I got an amber blinking low battery warning light.
In testing on this issue, the root cause appears to be actual battery performance or failure, which Windows 7 is reporting via the notification , but not causing. Now the red x is gone and things are going normal. Even worse, trying to do a search via Cortana's default search bar doesn't seem to do anything but bring you to Microsoft's website, or to the same battery management setting that doesn't address the issue here. While the exact cause is sometimes a mystery, it can be fixed. .
Whatever Microsoft is doing with this 0, null, unknown value for the Design Capacity variable, it is definitely affecting the battery in some way causing false alarms. If not, then please follow the next method. I took my desktop an Acer Aspire 6935g, that used to be a laptop before I bought and installed Win7 pro 64 bit , formatted a partition, deleted the hidden recovery stuff so I had a blank machine. You can buy longer life batteries for your current laptop if you wish,they're slightly more expensive but may be worth a look,an upgraded battery can in some cases have double the life of the stock battery. In my case, the hardware is barely 6 months old and the original battery should have experienced immaterial degradation, if any.
There seems to be two views about how to do this. . Reconnect the battery, then allow it to charge for one hour without powering on the laptop. The Windows battery meter reports the charge correctly, it is the actions it takes that are incorrect. Battery packs also self-discharge and will trigger the occasional topping off. Now if your battery works as it should in Ubuntu then you can try some of the below-listed methods to fix the problem.
I have a lot of experience with mac laptops and I can tell you that this thing is ludicrous. . . I understand that not all manufacturers allow for consumers of their branded products to change the threshold settings on power charging, but Microsoft has no problems greying out links that do not apply, they could do that here. I think these companies look at it through the eyes of the average consumer. They could add the link to the battery management menu under settings, and leave it up to manufactures to grey-out or leave as an active link to the currently obscure battery feature.
At which point the computer just shut down. Just answering on this to clear up some smoke: It's just wrong. Clearly you're just here to poke the bear, but I'll go along with it. The original battery would barely last 10 minutes, and he wanted a battery that would last an entire plane flight. Actually, I take that back. I'm on my second replacement battery now, which remains under warranty, and I still can't attain the same battery life that I enjoyed while using Vista.
The firmware provides information on the battery including manufacturer, serial number, design capacity and last full charge capacity. They're clearly spoiling for a fight with statements like these. I actually bought two new batteries to prove that it is not a hardware problem. My original Dell Inspiron laptop battery went from 2 hours plus to less than 15 minutes back in October 2009 after upgrading to Windows 7 from Vista. What new features would you like to see in a future release? There could be more out there. I've just disabled it and let the X60t sit for a while with no open applications. In testing on this issue, the root cause appears to be actual battery performance or failure, which Windows 7 is reporting via the notification , but not causing.
Ah, but new batteries don't solve the problem: the behavior is repeated. I has run perfectly for those years until 6 months ago when the original battery died. The design capacity will either read, 0, some random number, or unknown. I think my lapop is coming up two years old. I was thinking about this today.
