Can be your Notebook Battery Losing Life Fast?

 

Recently there have been many complaints by Asus notebook owners finding that the battery life of their newly purchased notebooks was deteriorating rapidly. Life of the battery would drop 35% after just a few months of usage. I decided to deliver as often real proof as it can be in this review showing which the concern is not the battery as such, but alternatively a firmware coding issue with the notebook that causes it to grossly under estimate actual battery life left and turn off prematurely. Put simply, the notebook thinks there is 0 – 5% battery life left when in actual fact there could possibly be up to 30% — or an hour’s valuation on life. This can be also a problem for other notebook users outside the Asus logo and is therefore worth anyone reading to comprehend the causes of a notebook to seal down when it thinks battery life happens to be critical.

I have owned the Asus V1JP for just two months now; I’ve been watching my life of the battery deteriorate every week. I understand such quick deterioration just isn’t normal therefore i would replace my battery thinking it turned out the problem. However, many users have reported the identical problem, traversing to a large number of wear and tear percentage on their batteries in a tiny time frame and thus causing far lower battery.

I didn’t finish up replacing my battery because I wanted to first further coordinate with some people for the Asus forum to find out how you get this concern.

 

Through the conversation from the very active thread discussing this topic, people suggested these as is possible solutions for “fixing” it:

 

None of those worked, as well as the battery callibration was suggested by Asus service center staff as a thing that should be done every few months, but this didn’t help.

 

Let me make an effort to explain why each one of these solutions wouldn’t work and why. Dell D630 Battery

 

Battery Calibration

 

Battery Calibration is really a Bios tool in which it is going to charge and discharge your battery to calculate your present degree of watts in your battery, basically your battery life (battery calibration tools vary by manufacturer, so consider your user guide).

 

Before I ran the calibration, Someone said that many had found this tool causing more battery wear after being run (or at best more battery wear was indicated), nearly 5% more wear than there was before. Despite understanding that, I attempted the calibration. I tried a normal calibration, when compared with jsis method of calibration. This takes a long time and unfortunately it wasn’t capable to rectify my wear percentage problem. Dell Latitude D610 Battery

 

My wear was 20% going into the calibration and after it absolutely was 25%. Then I attempted forum member jsis’ elaborate way of calibration which requires one to eliminate the battery half way over the charging process. Which did not solve my problem, but it did help jsis. Rather than helping, my wear had now increased to 30%. With 30% wear, after i take my laptop to school and employ it, I only get 120 minutes and fifteen minutes or possibly even longer — very dissapointing. I used to get three hours.

 

Battery calibration DOES take into account the ACPI (find out about what are the ACPI does for laptop power management at Wikipedia) when running this tool, meaning there’s software mixed up in process. The Bios is a factor. Should the calibration tool worked right, it should have reported my battery as 3 hours now, but after running it says I have couple of hours of total life indicating 30% wear.

More details on the ACPI will be explained later and just how as it happens being the offending aspect in this whole life of the battery issue.

 

Formatting and restarting your computer Dell Battery GD761

 

This really is another solution some members suggested to test, i did test it, since i have actually have a single week break from university! It’s known as “Reading Week”.

 

I made use of the recovery discs provided by Asus, after which had a go through the Windows Battery Miser plus it still stated only 120 minutes and a quarter-hour of battery life. I then thought we would completely reformat a laptop and used my Or windows 7 Pro CD and install the many drivers myself through the Asus V1 driver/utility CD. Everything went fine except now my Windows Battery Miser stated couple of hours of life of the battery — another 15 minute drop!

 

Then i installed a program called Notebook Hardware Control and Everest Ultimate, vacation programs that also report life of the battery; my wear percentage was now up to and including whopping 35% and battery continuing dropping. Dell Inspiron 1501 Battery

 

3rd party Programs

 

A couple of members stated the next party programs like Notebook Hardware Control and Everest Ultimate caused battery drain problems, making many members around the forum neurotic and crazed with this battery wear % and battery life problem. Dell M1330 Battery

 

However, vacation programs helped me realize why this concern is occurring. To start things off, many follow Windows Battery Miser as a reliable source for battery charge level and battery life. That’s fine, Furthermore , i utilize it myself.

 

Here’s finished ., compare your Notebook Hardware Control and Windows Battery Miser charge level and life of the battery. They’re the exact same, and do you wonder why? The reason being the foundation with the information is from the same place. This is called the ACPI (find out about just what ACPI does for laptop power management at Wikipedia), but sometimes be also assigned to the BIOS likewise. I will explain this further in the review. Dell M1530 Battery

 

In place, these third party programs and Windows Battery Miser are gathering their data from the ACPI and displaying that result, but the are the wrong values. And also this shows that the BIOS calibration tool is also utilizing the same ACPI source for your test, and so the calibration tool failed to do just about anything should alleviate the issue. If the ACPI is wrong, calibration won’t do a thing.

 

 

 

This screenshot shows how CoolMon2 takes data through the ACPI, which further props up indisputable fact that the ACPI is the problem.

 

What is the happening with the battery?

 

After completing and testing all possible solutions, I looked to my own solution and conclusions. I’d these theories: Acer Aspire 5517 Battery

 

I have tested a few of these aspects above, therefore have others. I’ve tested my battery to get bad, it’s not necessarily, I am going to explain why further from the review, since it leads the workaround to the present problem.

 

There’s bad coding, because We have tested it above, look some tips i have been right through to solve this matter in fact it is still not rectified with those suggestions.

 

Many have had their motherboards replaced to solve this matter but in many instances this didn’t solve the challenge, some also attribute this to bad circuitry that is not the issue.

 

Could it be user abuse? Not necessarily, because Image here for this kind of extended timeframe, just like many others, we understand how to take care of our notebooks, so please don’t refer to this abuse on our end.

Now that basic fundamentals of what is happening in the shadows for the Asus forums, I just did a test showing what the results are in your battery life as well as the workaround.

 

Numerous have previously read my review about the Asus V1JP I’ve had for just two months now, my battery test showed I bought three hours of battery life right once i first got my laptop. Obtain I used to be losing roughly 3-5% battery wear and server a minutes of battery as time passes. Yet again I will be employing the same settings because of this battery life test.
