Windows 8 low battery notification. How to get rid of annoying Android shortcomings. Increased battery life

As you know, many Windows tablets cannot boast the same long time battery life, which we are used to on tablets with the Android operating system on board, so we have to charge them much more often.

At the same time, we constantly have to monitor the battery level of our devices, and it would be nice if our Windows tablet or laptop itself gave us signals when its battery charge during operation (or recharging) reached certain levels.

Currently, there are several theories regarding what levels a tablet or laptop battery should be kept within.

One of them says that to ensure the longest possible service life, you can keep your laptop or tablet constantly connected to the charger and most importantly, do not allow the battery to discharge too much.

The second theory says that it is best to keep the charge level of a lithium battery between 40 and 95 percent.

In both cases, we need to constantly monitor the level of discharge or charge of the battery of our devices and not allow it to go beyond the established limits.

Today I want to tell you how you can automate this process.

How to set a low battery warning Windows tablet or laptop

Low battery warnings are easy to set. To do this you need to do the following:

1. Go to “Control Panel” -> “Hardware and Sound” -> “Power Options”

2. Open the current power plan and click on “Configure power plan”

3. Click on “Change” additional options nutrition"

4. In the window that opens, open the “Battery” item by clicking on the “+” next to it

5. Here you can set the level at which the battery is discharged to which you will receive a corresponding warning.

Warning when your tablet or laptop battery reaches a certain level

With a warning that the battery charge of a tablet or laptop has reached a certain level when charging it, things are a little more complicated.

Here we need a special script (set of commands), which you can create in the Notepad application by simply copying the following text into it:

set oServices = oLocator.ConnectServer(".","root\wmi")

set oResults = oServices.ExecQuery("select * from batteryfullchargedcapacity")

for each oResult in oResults

iFull = oResult.FullChargedCapacity

while (1)

set oResults = oServices.ExecQuery("select * from batterystatus")

for each oResult in oResults

iRemaining = oResult.RemainingCapacity

bCharging = oResult.Charging

iPercent = ((iRemaining / iFull) * 100) mod 100

if bCharging and (iPercent > 95) Then msgbox "Battery charge: " & iPercent & "%",vbInformation, "Battery Monitor"

wscript.sleep 300000 "5 minute battery polling interval

wend

This script, authored by John Howard, polls the battery level every five minutes and, when it reaches 95 percent, issues a sound signal and a corresponding warning.

You can set the charge level for the warning in the third line from the bottom (iPercent > 95), changing 95 to the value you need, but not more than 99%.

After you do this, save the script to your desktop under any name, but always with the .vbs extension

For example: battery.vbs

That's it, now if you run this script, then when the battery level reaches the level you set, it will give you a warning about this. If you want the script to automatically run every time your device starts, place it in the startup folder.

You probably noticed that in the above script you can set the battery level to no more than 99%. But what if we need to receive a notification when the battery is fully charged to 100%?

In this case, you can use the script I created based on John Howard's script:

set oLocator = CreateObject("WbemScripting.SWbemLocator")

set oServices1 = oLocator.ConnectServer(".","root\cimv2")

set batItems = oServices1.ExecQuery("Select * from Win32_Battery")

while (1)

for each battery in batItems

ischarged = battery.BatteryStatus

if (ischarged = 2) or (ischarged = 3) Then msgbox "Battery is charged!",vbInformation, "Battery monitor"

wscript.sleep 300000 " 5 minutes

wend

Next time we'll talk about why some tablets drain the battery quickly in sleep mode, and also about methods to combat this problem.

On my Lenovo laptop Y410 I installed Windows7. I used to have Windows XP. In XP I received a low test notification when my battery reached 10% life. In I even set the low notification notification but still it does not notify me when the battery reaches 10% life and when it reaches the critical level of 5% it automatically goes into sleep mode. This annoys me.

Can anyone tell me why it doesn't notify me when it reaches low level testosterone? I use a balanced diet. Low test tone notification is enabled and battery level is 10%. The critical battery charge level is 5%.

UPDATE: During a problem with internet search, I kept my laptop on battery and every minute I watched the battery level. Previously, when I used Windows XP, it lasted 3 hours with dim light. Now in Windows 7 it lasts for one hour and as some other user asked a question saying battery life suddenly drops from 26%-5% (question here) even my laptop right after I saw 26%, it went into sleep mode according to the action of the critical level. I admit that some things are similar to this user, such as my battery is a year old. But I don't understand why it started suddenly when I upgraded to Windows 7 from XP. This is a little iffy for me. Should I accept the solution given in this question, or is there another thing I should try?

This is already the case, then it could be a battery problem. For example, one message in this question. To check, change notification percentage O low battery level to a larger number, such as 30%. Then watch, wait and learn.

Steps to change notification percentage:

[Right click] power icon
Select power settings
Click Change settings power of the selected power profile
Click Change advanced power settings
Scroll to and select Battery through [+]
Expand Low battery level
Change battery On 30% or higher

Here are some more reasons. An error related to Vista has appeared. However, some problems are related to the BIOS. So try updating it. Another solution is to remove the battery and clean the contacts using a pencil eraser. One person said that when he or she changed the action Critical Battery to " Shut down" from " Hibernate", a low battery notification appeared.

EDIT: The notifications you can set are only battery [level, notification] and spare battery * [level]. There is no critical battery notification in Win7 [level and action only].

If, for example, you set the low battery to 6% and the critical battery to 3% [the lowest bypass is accepted], you can set the spare battery to 4% to act as a final ditch warning for the electrical connection until The battery operates without any additional warnings.

[* The reserve battery level is not associated with any action other than the warning alert - “Critical Battery Alert. Now you are working in backup power. Your battery is very low (4%), please connect immediately. No, your computer will soon automatically go into hibernation. "]

So to sum it up - your spare battery level should be HIGHER than the rest.

The battery charge level is displayed as a battery image in the area Windows notifications. More accurate information about the charge level (as a percentage, where 100% is a fully charged battery) can be found in the tooltip that appears when you hover your mouse over this icon. But the user may not notice that the battery is almost completely discharged. Therefore, Windows provides a low battery notification mode, as well as actions that will be automatically performed when the battery level is low and critically low.

Open the Power Options dialog box. Let me remind you that you can open it from the Edit Plan Settings window.
Expand the Battery group, and then expand the Low battery notification subgroup.
Make sure the On link appears to the right of On battery in the Low battery notification group. If the Off link appears, click it and select On from the drop-down list that appears. Low battery notification mode is enabled.

By default, 10% of full charge is considered low. You can change this number by expanding the Low battery level group and selecting the desired value. So, for example, you can set the low level to 50% and the low battery notification will appear when the battery is down to 50%. In the Critical battery level group, the critical battery charge level is set. By default, this level is 5%, as a discount when you invite a toastmaster to a wedding Moscow prices. With such a discharge, the laptop can only work for a few minutes.

To define the action that will be performed when the battery is low, expand the Low battery action group and select the appropriate action: do nothing, put the laptop into sleep mode, hibernate mode, or turn off the laptop. You can also define the action that will be performed when the battery level is critically low by expanding the Critical battery action group.

When choosing an action when the battery is low or critically low, it is best to choose to put the laptop into hibernation mode. When you enter hibernation mode, the contents RAM registers on hard drive and is restored when the laptop is turned on. This way, you won't lose data that you didn't have time to save before the battery died.

Google annually adds many settings and functions to the Android operating system, many of which are hidden from the eyes of ordinary users. This was done on purpose, but with good intentions. The American corporation believes that if an inexperienced owner of any inexpensive Android smartphone accidentally activates certain important settings, then his device may start to work slower or discharge much faster, so right out of the box, all smartphones based on Google’s OS have only basic activated functionality, but this is very easy to fix.

Although every year all smartphones work longer on a single battery charge, largely due to better software optimization for hardware, but hidden setting in all Android smartphones, it significantly increases battery life, and now absolutely anyone can activate it, since it is definitely available in any custom firmware and in all models of mobile devices.

All smartphones based on operating system Android has an incredibly large reserve of power, which is simply excessive for simple everyday screen tasks. It's like driving a car, sometimes pressing the gas to the floor, and then slowing down again. In the case of smartphones, it’s not the gas that drains faster, it’s the charge. battery. To increase battery life mobile device you need to launch “Settings”, and then go to the “Battery” section.

In the “Battery” section, three vertically located dots should be visible in the upper right corner, which you need to click on. In the menu that appears, you will need to select “Power Saving Mode” and then activate it. As a result, the processor performance will be reduced, which will allow up to 50% increase in battery life on a single battery charge. This feature is available in all smartphones and tablets running Android 5.0 Lollipop and higher.

To achieve an even greater effect, the editors of the site recommend installing the “Doze-energy-saving” application, which significantly increases the battery life of all Android smartphones, since a lot of charging is “eaten up” by processes running in background, which the user does not even see. After installing it, you need to select from the list only those programs and services that should continue to function normally.

It is worth choosing the most basic messengers, email clients and other core programs that need to receive notifications in real time rather than delayed. This program works in such a way that all processes that are running in the background and consuming battery power are automatically frozen. This does not cause any harm to them or the data stored in them, and using this application can significantly increase battery life by up to 40% of the standard. This is especially noticeable at night, when without this program the smartphone’s battery will be discharged by 10-12%, and with it only by 5-6%.
