Battery drains suddenly from 18% to 5% , laptop hibernates

[ashb4444]

Hello,
I bought a new Aspire E5-572G-525V laptop and using windows 8.1, but I am facing a battery issue. I have noticed that whenever the battery level reaches aound 18%, the battery suddenly drops to 5%-critical level without giving a low battery indication and the laptop gets hibernate.
I have tried all the possible ways like to set the low level battery level indication in advanced battery options, re-installing the microsoft battery driver etc. but nothing has worked.
Is the battery is defected or is it any hardware or software issue? Please help. Thanks!

How long ago did you purchase this?

In the past, I have had to "train" my laptop batteries. You do this by using the laptop on battery until there is absolutely no juice to start it up, charge it again, to full - Try not to overcharge it, then use it on battery until it absolutely will not start - do this about 4 times, and it will train your battery. To make this easier, you will have to adjust your Laptop power settings, so it does not go into sleep or blank out the screen in 5 minutes, give it s good 20 minutes before the screen blanks, and 30 before it goes into sleep mode or shuts off. Power settings should be in the same area where your Screensaver settings are. Then just use the PC until it shuts off on you, keep turning it back on until it will no longer turn on, then charge it full again, repeat 4 times.

However, some new laptops have firmware that will do this for you, Check in your BIOS, I suppose you can only get to it through advanced startup in the PC Settings section of 8.1. Get into your BIOS (if you can, because that is an ongoing issue with Windows 8, 8.1 and 10 - Not being able to get into BIOS from Windows while using UEFI boot mode).

Because it is pretty important that you do be able to get into your laptop BIOS, if you can't, go into the tutorials section and search "Legacy Boot mode" or "Legacy BIOS" and bookmark what you find, it will tell you how to enable Legacy Boot if you can't get into your BIOS from Windows 8.1.

But assuming you CAN in fact get in there, once you get in, check for any utilities that can train your battery. You also may have an alternate WinRE partition or a Diagnostic partition with such tools on it. Before Windows 8, these partitions were accessible via F keys or from your BIOS. Today, it's all done from within Windows PC Settings under Advanced Startup. Look for a Diagnostic partition, if you have one, it will be marked in your advanced Start menu, which will appear after the laptop reboots once you have pressed the initial "Advanced Startup" options in PC Settings. If your laptop has such a battery training tool, use it, that will save you having to drain your laptop manually.

But once you train your battery, it should no longer jump all the way down like that.

Well I have a Dell Vostro (Intel i3) that does exactly this, from 18% right down to 5. If you have a warranty, you may be due a new battery. Sometimes a new battery will be bad. Might have a bad cell or something. But I would train it first to see if it still does this. Just use the laptop until it dies, charge it up to 100, then do it again, about 4 times. Then, if it still does it, get the battery to 20%, then bring it to where you got it, then demonstrate it, Unless you bought it online. If so, contact the seller and explain it just how you did in your 1st post. But it may not be the battery itself, might be the power block on the laptop, You'll have to find a laptop repair that can test it for you. Sometimes where you bought it will be able to do that too.
