No "Low Battery" Warning Appears Before My HP Laptop Hibernates

[ADonMartini_790]

Honestly, this has been happening for a little while now; fortunately, it hasn't done any harm other than annoy and frustrate me, but I finally ran out of patience and decided to ask the HP Support Community for some assistance.

The title is self-explanatory...whenever I use my HP Pavilion laptop without a charging cable hooked up, especially early in its use (it's a little over two years old now), I usually get a couple of warnings that the battery is running low on power: first, the screen dims once the battery gets to about 20%, and a "low battery warning" message appears on screen once it gets to about 10%-12%. However, maybe two times out of three, I get no warning signs at all of a low battery. The screen doesn't dim, no message appears, and the computer instantaneously goes into hibernation in the middle of activity. What's more, once I connect the charging cable and restart the computer, the battery icon shows the battery is at 0%, even if the same display read in at 30% nearly a half-hour earlier. Maybe once out of three times, the monitor brightness will dim ahead of a potential cutoff, but too often as of late, the "low battery" warning may appear literally two seconds or less before the laptop goes into hibernation. Fortunately, I haven't lost vital information when this has happened so far, but I don't intend to wait until it does before I ask for some help in fixing it. The only real thing I've done is adjust the Control Panel's Power Options from "HP Recommended" to "Balanced (recommended)," but the sudden shutdowns haven't stopped.

As usually done before I post a message here, I do an online search for the issue, and I found that this also seems to be a common issue for other users, as the below links suggest:

• Low Battery Warning Does Not Appear
• HP Pavilion battery drops to 0% without warning
• Laptop shuts down without warning on low battery when not plugged in
• Why is my HP laptop turning off without giving any low battery level warning?
• Laptop shuts down (low battery) without warning.
• laptop shutting down before battery is low

I don't know if my case is unique from the others, so I didn't blindly repeat the suggestions made in these previous questions; instead, I wanted to check with the community and ask what exactly seems to be the problem, and what exactly could be done to correct the issue. Whatever help given is appreciated.

Thanks in advance,

Hello @ADonMartini_790 .
You can edit the power plan and select up to what percentage you want the computer to be put to sleep.

If the percentage is not respected, then keep Windows and make sure you have updated the bios.
Before updating the BIOS, check the installed version.
Simultaneously press the Windows key + R, a window will open and type msinfo32 and click OK, look for the line that indicates BIOS date and check if the version is the most current compared to the one on the https://support.hp.com/mx-es/drivers page, if you have already checked the version and you do not have the latest version, then download it to update it.

If it does not work either, it is because the battery for all the time it has been in use is already worn, so, with this I mean to imply that the battery can drastically change the percentage of charge status, and the system may become unable to detect these changes and may be the reason that the operating system does not respect the percentage that you have put in the power plan to suspend the computer.

Hello, @GOLD_MASTER -- I appreciate the time you've made to reply.

I'll test out your recommendation and let you know how it works out in a couple days. I've had the computer for a couple years now and have used it a lot; on average, the battery lasts for about a hour and fifteen minutes without a charger before suddenly suspending itself. Assuming the battery doesn't need replacing, I'll apply your technique to see if it helps at all.

Thanks again,

@ADonMartini_790 .

Consider that the battery already has a useful life span, and commonly they do not perform the same in one year or after one year of use.

[ADonMartini_790]

@GOLD_MASTER: that makes sense, I guess -- perhaps the useful life runs out faster depending on how active one is with their device. Not that I have a huge problem with keeping the charger attached to the computer at all times, but conventional wisdom says that it kills the battery's ability to hold a charge if it is always "charging" needlessly at full capacity. So far, the battery can go about an hour and a half -- give or take -- before it runs out, and doesn't display the low battery warning before hibernating altogether. I'll try to tweak the settings like you say, and hopefully it might save me the trouble (for now) of having to invest in a new battery altogether. Thanks a ton for your advice 🙂

And to everyone else, feel free to chime in with any other suggestions you may have to resolve this issue -- even if the battery isn't as strong as it was when it's new, the warning system could at least be better. The worst time to warn me that a shark is coming is after it already bit me, and this is no different.

Thanks in advance,

What you could do is calibrate the battery to make it perform a little better, however, the battery is a candidate for replacement as its life/performance cycles are not very long.

[ADonMartini_790]

Hello again, GOLD_MASTER; sorry for the wait, as the last few weeks have been busy. Useful info, as expected; I'll be sure to keep you posted once I'm free to sit still and apply any tweaks/calibrations as recommended, at least giving that a change before I move towards a full replacement of the battery.

That is, unless I get frustrated enough to just do it -- LOL.

Thanks again,
