The laptop does not warn about low battery. Hidden customization in all Android smartphones dramatically improves battery life

the Internet

As you know, many Windows tablets cannot boast the same long time. autonomous workwhich we are used to on tablets with an operating room android 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 reached certain levels during operation (or recharging).

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

One of them says that to ensure maximum long term its services, while working, you can keep a laptop or tablet constantly connected to charger and the main thing is not to let the battery discharge too much.

The second theory is that it is best to keep the charge level. lithium battery ranging from 40 to 95 percent.

And in either case, we need to constantly monitor the level of discharge or battery charge 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 on a Windows tablet or laptop

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

1. Go to "Control Panel" -\u003e "Hardware and Sound" -\u003e "Power Supply"

2. Open the current power plan and click on "Set up power plan"

3. Click on "Change advanced power settings"

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

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

Alert when your tablet or laptop battery reaches a certain level

With a warning when a tablet or laptop battery reaches a certain level while 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 \u003d oLocator.ConnectServer (".", "root \\ wmi")

set oResults \u003d oServices.ExecQuery ("select * from batteryfullchargedcapacity")

for each oResult in oResults

iFull \u003d oResult.FullChargedCapacity

while (1)

set oResults \u003d oServices.ExecQuery ("select * from batterystatus")

for each oResult in oResults

iRemaining \u003d oResult.RemainingCapacity

bCharging \u003d oResult.Charging

iPercent \u003d ((iRemaining / iFull) * 100) mod 100

if bCharging and (iPercent\u003e 95) Then msgbox "Battery Charge:" & iPercent & "%", vbInformation, "Battery Monitor"

wscript.sleep 300000 "5 minute battery charge poll interval

wend

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

You can set the charge level for warning in the third line from the bottom (iPercent\u003e 95), changing 95 to the value you need, but not more than 99%.

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

For example: battery.vbs

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

You may have noticed that in the above script you can set the battery charge level to no more than 99%. But what if we need to be notified when the battery is fully charged to 100%?

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

set oLocator \u003d CreateObject ("WbemScripting.SWbemLocator")

set oServices1 \u003d oLocator.ConnectServer (".", "root \\ cimv2")

set batItems \u003d oServices1.ExecQuery ("Select * from Win32_Battery")

while (1)

for each battery in batItems

ischarged \u003d battery.BatteryStatus

if (ischarged \u003d 2) or (ischarged \u003d 3) Then msgbox "Battery charged!", vbInformation, "Battery monitor"

wscript.sleep 300000 "5 minutes

wend

Next time, we'll talk about why some tablets run out of battery quickly in sleep mode, as well as how to deal with this problem.

Android is really excellent operating system, but at the same time has its drawbacks. Some of them are congenital and you only have to put up with them, others can be quite easily eliminated. In this article, we have collected some of the most common android problems and tips to fix them.

Longer battery life

This is still one of the biggest disadvantages of mobile gadgets. Manufacturers continue to release smartphones with a lifespan of less than one business day. It is clear that the design features of modern batteries and the ever-increasing needs of devices have entered into deep contradiction. However, there are ways to solve this problem.

When buying a gadget, please contact intent attention to battery capacity... Yes, you may have to pay a little more for this pleasure, but the freedom from socket dependence is worth it. Take a look at Motorola's MAXX lineup, samsung series Galaxy Note and other devices that can show an outstanding survival rate.
Buy an extra battery... If you have no current plans to buy new phonethen it is better to purchase an extra battery. It can be either just an additional battery or replacing the existing one with a more capacious one.

You can do this at night if you are not expecting important calls. Disconnecting all communications reduces energy consumption to almost zero.

Get rid of junk software

Manufacturers and sellers install a huge amount of unnecessary commercial software for many device models. And that can turn into a real problem. The software imposed on you not only takes up space, but also eats up system resources, consumes battery, and simply interferes. Fortunately, there are ways to fix this.

Disable them in system preferences. Most of these programs have system status and cannot be easily removed. If you do not want to root the device, then you can almost always go into the settings and disable the programs you do not need, as shown in the illustration above.
Get root and remove trash... Obtaining superuser rights is not such a terrible procedure. You can use either article. After that, you can completely uninstall or just freeze the programs you have selected. For this there is a large number of special utilities, the most popular of which Titanium Backup and RootAppDelete.

Hide or eliminate branded skins

Many manufacturers use branded launchers on their devices, which, however, may not be very convenient or consume too much system resources... This problem can be solved either by fine-tuning the corresponding shell or by completely replacing it.

Go back to stock Android as much as possible.If you want to solve the problem " with little blood", Then you will have to select and replace the launcher, keyboard, dialer, calendar and so on with real ones. google apps... How to do it on android example 4.4 we told in these articles (,). Pay attention also to third party applications, which are sometimes distinguished by even greater capabilities and low consumption of system resources. You can start, for example,.
Flash third-party firmware... If you are leaning towards a more radical and complete solution, then you will have to reflash your gadget with one of the third-party firmware. Developments such as have long since come out of baby diapers and provide quite stable, convenient and safe operating systems.

Turn off annoying notifications

As a rule, almost all programs have a corresponding section in the settings. Just do not be lazy to look for the options responsible for what, when and how often the application will display in the notification bar. This, incidentally, can further reduce battery consumption.

There is also a more radical way. In Android 4.1 and higher, you can open the application page in the system settings and generally disable all notifications from it. Just uncheck the box Show notificationsas shown in the picture above.

Set the correct orientation for each application

Some programs look great in portrait orientation, others in landscape orientation. To put this under control, use the Smart Rotator utility, which provides us with a single interface to control these parameters and allows you to choose which applications will use. automatic rotationand which ones will always stick to vertical or horizontal orientation. It is especially good to use this program on tablets.

On my lenovo laptop Y410 I installed Windows7. I used to have Windows XP. In XP, I was getting a low test notification when my battery reached 10% of its life. In I even set a low notification notification, but still it doesn't notify me when the battery reaches 10% of life and when it reaches critical level 5%, it goes to sleep automatically. It annoys me.

Can anyone tell me why he doesn't notify me when he reaches low testosterone levels? I am using a balanced diet. Low test tone notification is on and battery level is 10%. The critical battery level is 5%.

UPDATE : During the problem with searching the internet, I kept the laptop on battery and every minute I watched the battery level. Earlier when I was using Windows XP it lasted 3 hours with dim light. Now, on 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 here) even my laptop right after I saw 26%, it went to sleep 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. But I don't understand why it started all of a sudden when I upgraded to Windows 7 from XP. This is a little doubtful for me. Should I accept the solution given in this question, or is there another thing I should try?

Here are a few more reasons. I got a Vista related error. However, there are some problems with the BIOS. So try updating it. Another solution is to remove the battery and clean the contacts with a pencil eraser. One person said that when he or she changed the action Critical Battery on " Shut down "From" Hibernate », A low battery notification appears.

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

If, for example, you have installed a 6% low battery and a critical 3% battery [lowest bypass is accepted], you can install a 4% spare battery to act as the last utility ditch warning until Accumulator battery operates without any further warning.

[* Battery backup level is not associated with any action other than a warning alert - “Battery critical warning. You are now in standby power mode. Your battery is very low (4%), please connect immediately. No, your computer will automatically hibernate soon. "]

So, to summarize - your spare battery level should be HIGHER than the rest.
