For users of laptops with operating system Windows 7, sooner or later you will surely get a notification "consider replacing your battery" is accompanied by the appearance of a red cross on the battery icon in the system tray. Notification that appears when Windows 7 "assume" it's time your laptop's battere placed.
Please note that this notification appears when Windows 7 detects that your laptop battery capacity is less than 40% capacity should be, and therefore it is proper to be replaced. However, many reports from users of Windows 7 in different parts of the world that states that Windows 7 sometimes wrong in the detection capacity of the laptop battery. There was even a user who had to replace the battery with a new laptop but still get this notification.
Regardless of whether or not accurate in detecting Windows 7 laptop battery capacity, I think we agree that the laptop battery is an expensive item. So long as it can be used well (despite being less than 40% capacity is ideal), so no need to be replaced. I personally think that as long as the laptop battery can survive more than 30 minutes then it is not the time to be replaced.
If you are having problems "consider replacing your battery" as above, you do not need to panic or rush to spend deep to buy a new laptop battery. There is a simple way to eliminate those annoying notifications. Here are the steps:
1) Charge your battery to full (99% - 100%), after that turn off your laptop. Until this stage do not always unplug the charger it.
2) Turn on your laptop and press F8 repeatedly until the Advanced Boot Options menu appears. Select Safe Mode.
3) Having already entered into the Windows Safe Mode, then unplug the laptop battery charger
4) Let it burn to death their own laptop because the battery is completely discharged. It is advisable not to operate your laptop during this process. Leave it until the laptop turns itself off.
5) Once dead, replace your laptop charger, then turn on your laptop normally. The result ... all back to normal! Notifications "consider replacing your battery" and red cross on the battery icon does not appear anymore.
The above technique is basically a way to calibrate your laptop battery capacity. By running laptop starting from the initial condition the battery fully (100% capacity) until it is completely empty (0% capacity), and Windows 7 so it "knows" the true capacity (real capacity) of a laptop battery, and automatically reset parameter settings to -parameters related to laptop battery.
This method has been tested to 2 different laptops, namely HP and Acer, and proved both successful outcome. So, you now do not need to be confused anymore when notified "consider replacing your battery" in your laptop.
Note
Based on the explanation engineer Windows 7 in one of the official release on the Microsoft website, explained that the actual notification was originally intended to be one of the reliable features in Windows 7 (it does not exist in Windows XP or Windows Vista), whose purpose is to inform users that the laptop battery is worn out and so it was time to be replaced.
But in fact, many users of Windows 7, which was disturbed by the appearance of this notification. Some have argued that the limit (threshold) 40% considered too great considering the capacity of the 30%-an ideal capacity of any laptop battery can generally last about 1 hour, and that's not quite enough for laptop users. Besides laptop battery price is quite expensive to make many users are reluctant to replace the laptop battery unless it is completely broken.
But not a few who think this "feature" is a bug, considering the number of cases where Windows 7 was proven wrong in detecting the true capacity of the laptop battery. I personally consider including this as a bug! Why? Because when I got notifkasi HP laptop, I tested with to charge the battery fully and then enter Windows normally (not Safe Mode) and select Power Saver option and squelched.
As a result, in just 48 minutes my laptop is dead (the battery runs out). When it was my calibration and notification is gone, I do the same thing. I charge it up and then enter Windows normally and then select Power Saver and squelched. The results were different! Need waktuh 1 hour 24 minutes before my laptop died in the batteries run out of power. So there is a difference of about 40 minutes here, and I think a 40-minute difference is very significant indeed.
