On my Lenovo Y410 model laptop I've installed Windows7. Earlier I used to have Windows XP. In XP I used to get low batter notification when my battery reaches 10% life. In Windows 7 I've even set the low batter notification on, but still it doesn't notify me when battery reaches 10% life and when it reaches critical level 5% it automatically hibernates. This is getting quite irritating for me.
Can anybody tell me the reason why it is not notifying me when it reaches low batter level? I'm using balanced power mode. Low batter notification is on and low battery level is 10%. Critical battery level is 5%.
UPDATE: During googling the problem, I kept my laptop running on battery and I was observing the battery level every minute. Earlier when I was using Windows XP, it used to last for 3hours with dim light. Now, with Windows 7, it lasts for one hour and as some other user asked a question saying that battery life suddenly drops from 26%-5% (Question is here) even my laptop right after when I saw 26% it went into hibernate mode as per the critical level action. I admit that some things are similar to that user such as my battery is a year old one. But, I dont understand why this started happening suddenly when I switched to Windows 7 from XP. This is bit doubtful to me. Do I need to accept the solution given in that question, or is there any other thing should I try?
