HP Envy 13t shuts down on 50% battery

[drbrandman]

Laptop is about 2 years old.  For months now, laptop will just immediately shutdown; no warning; no error messages. Can not start it up again without either recharging it or putting it on power.  Happens when battery indicator is at about 50%

In power plan have set critical batter down to 5%; low battery setting is 20%.  No error messages of any sort when system does start up again.  When shutdown occurs, appears as if it is going into hibernation - not a total crash.

I have run through the battery diagonistic at boot (F2 on startup) and it tells me the battery is fine - does not need to be recalibrated.  This is very frustrating.

The simple OK message from the battery test can be misleading. You need to take a deeper dive into the advanced test results to see how old the battery is how many cycles and the charge capacity of each cell. 2 years is long enough that the most likely thing is you need to replace the battery.

Thanks for your reply. Where does one look to take this deeper dive? I do not see any "advanced" button to push while viewing the brief report, nor do I see a log file left behind on the drive.  Also, it's not so much that I am complaining about battery life, as it that I want the system recalibrated so I see a better picture as to where I am on the current battery charge.

Not super easy to see:

This is the test in HP Support Assistant. The one in pre-boot UEFI diagnostics (esc then F2 and component tests-power/battery) is similar. 

Post back advanced results. If the battery is bad calibration is not going to be an option.

Thanks - ran the Battery diagnostic again and looked at the advanced information, after bringing batter to a full charge. (I am now in the process of fully discharging battery after setting Low and Critical Battery levels as low as they can go). Then will charge it again.  Things of interest to me were 

a) Battery showed OK

b) Showed still at 80% capacity

c) Cell 4 shows 0 mV

[Huffer]

Actually 95% capacity. That is a healthy battery but now we know that. 

Can you calibrate it now?

[drbrandman]

I'll see how the calibration process works - fully charge, then fully discharge, then recharge.  However, the way I have been using my laptop, that should have been happening alot.  I get up in morning, and laptop has been on charger.  I go through my morning routine with laptop off charger. Usually within 2 to 2.5 hours, it just suddenly hibernates. Battery display usually shows about 50% at this point.  Then I recharge.  Only real difference is that the Criical Battery level is set to 10% and low batter to 20%.  I never get a low battery warning.  We'll see how this goes.  I'm concerned that one cell is dead. Read up on replacing the battery - doesn't seem terribly difficult, but not as simple as some other laptops I've deal with.

Will report back with my results.

That zero report on one cell is normal. Mine shows 2 zero cells:

[drbrandman]

Well, I am going to just accept things as is. After going through the procedure - Fully charge; discharge; recharge, things are exactly the same. When I was discharging, the system blacked out at 52% battery. When I plugged the laptop back in, it was showing 52% battery. There was never a warning message. I will (or already have) learn to accept that the machine will do this at this battery level. Battery life (depending on what I am doing) is a little over 2 hours to get there. Oh well.

Hello!

I have almost the same problem with my notebook HP Envy 13-d005np (battery with 3 cells). I bought it in 2015 and is no more under warranty. It hibernates without warning at 30% - 35%. I've already done:

- a manual calibration;

- many tests with hp software (uefi included);

- installation of the last bios available;

- format the hard drive and install the OS (Windows 10 64 bit).

Any suggestion? Thanks.
