Nobody wants to suffer with a low battery situation. We show you how to fine-tune and calibrate your laptop battery so you can squeeze more time out of it.

1. Laptop: ACER ASPIRE E1-470G. Os: Windows 8.1 Single Language My Laptop turns off when its 30% Battery, 10% was set on critical battery level as default so I was excepting to reached that level before my laptos turns off, but I regularly do connect my ac adapter about 40% just now I forgot to connect it. Before it turns off I notice it was 30%.
2. I recently replaced my Acer Aspire V5-571 battery because the old one wouldn't charge (0% plugged in, not charging). My Acer Aspire E 14 battery is not charging, it only blinks orange light. Acer Aspire E5-771G internal battery does not charge anymore. Charging / Battery problem Acer Aspire V3-571G.

Battery life seems like ass to me (aspire 5) ok so Im basically a baby and this is my first computer ever so I don't know shit. I bought an aspire 5 a few days ago and I noticed that it runs out of charge pretty fast.

There are two simple ways to correct electric quantities.

Standard calibration via BIOS

The vast majority of brand name laptops have a Battery Calibration program built straight into their BIOS.

Step 1:

Power on the laptop and hit F2 at the boot screen to enter BIOS. Choose the Power menu using the cursor keys.

Step 2:

Choose Start Battery Calibration and then press 'Enter'.

Step 3:

The screen should turn blue. According to the on-screen tip, you should plug in an AC adapter to charge the laptop to full; afterwards, unplug the AC adapter.

Step 4:

The laptopwill continue discharging until it automatically shuts down. Once it does, plug in a power adapter to charge it again, however do not start the laptop or boot it.

Once the laptop has been fully charged, the battery calibration has completed.

Manually calibrating the laptop battery

If there is no Battery Calibration option in BIOS, you will need to conduct a manual calibration of the laptop battery.

Step 1:

Boot the laptop, and go into your laptop’s power management settings.

Step 2:

Now click 'Change plan settings'.

Step 3:

Go to 'Change advanced power settings' and select 'Battery'. Click 'Critical Battery Action' and set it to hibernate.

Next, click 'Critical Battery Level' and set it to 5%.

Step 4:

Once all settings have been updated, you should close all applications. Remove the power cord and let your laptop discharge until it automatically shuts off.

Wait for a few hours, please plug the power cord back in and charge up to 100%.

Note: if you want to calibrate your laptop while not in use, you should make sure the following options are all 'Never'.

Let the notebook sit for a few hours until it shuts down automatically. After calibrating, ensure all the power settings are set to their normal values before using the notebook.
