How to change critical battery level to 1%
I would like to change the critical battery alarm to 1%. But Win 7 only goes down to 5%. How to get lower? http://www.thewindowsclub.com/wp-content/uploads/2010/01/battery-notifications.png

Setting the critical values too low, makes no sense. Even planned actions like shutdown, going into hibernation, etc. need some power. What's more, no battery likes to be completely discharged."I think there is a world market for maybe five computers. (Thomas J. Watson, Sr.)

it's what the customer wants.

Beat'em up. With some cheating, it may be possible to do what you want - but there's no good reason to do that. Can't you explain that to your customer(s)? Or, alternatively, did he mention any reasons to accomplish such strange experiments?"I think there is a world market for maybe five computers. (Thomas J. Watson, Sr.)

/offtopicFrankly I also have it set to 1% on my old netbook. Don't really see the point to setting the critical alarm to 5% which means almost 15 minutes of computer use. However I do set the low battery alarm to around 7%. /ontopic Managed to bring it to 1%. I ejected the battery and then set it to 1% and after wards inserted the battery.

at 1% it automaticly hibernates the PC which always takes less than a minute. So there is some time to spare.

GRIT FYI netbooks don't really need heavy 9cell batteries to run for 5hours.

Thanks, I want to try this. Reason? Going critical at 6% on a battery that last for 500 minutes is way too much juice left when entering "critical". Microsoft needs to address the larger batteries out here. Running Windows7 on a Asus Eee (2GB ram and 64GB SSD)

Here is the solution. You must use powercfg.exe in Windows 7. powercfg.exe -setdcvalueindex 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c e73a048d-bf27-4f12-9731-8b2076e8891f 9a66d8d7-4ff7-4ef9-b5a2-5a326ca2a469 20 The 2 things you need to change are 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c (power scheme GUID) and 20 (what percentage to set it to). To locate your power scheme GUIDs, open registry editor (regedit.exe) and go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\User\PowerSchemes. The keys (i.e. folders) underneath that location are your GUIDs. I believe the GUID above is for the High Performance power scheme. Here’s the command to set the Balanced power scheme to have a critical battery level of 10%: powercfg.exe -setdcvalueindex 381b4222-f694-41f0-9685-ff5bb260df2e e73a048d-bf27-4f12-9731-8b2076e8891f 9a66d8d7-4ff7-4ef9-b5a2-5a326ca2a469 10

The Power Options in Windows 7 on my computer won't let me set the critical battery level below 7%. And yet, the user manual for my computer specifically says "To prolong battery life and optimize the accuracy of battery charge displays...Allow the battery to discharge below 5 percent of a full charge through normal use before charging it." It makes it seem as though they are deliberately trying to reduce my battery life (by not allowing me to operated to the recommended 5%) so I am forced to buy a new battery sooner. And I'm not very tech savvy so I'm afraid to mess with the powerconfig.exe as suggested by others on this thread.
