Computer shutdown without ac power

[bramdc]

When i disconnect my AC power cord, my laptop falls without of power

in a short time but my battery has still enough off power.

I tested the battery, (see picture below)

Will that mean that my battery is broken or too old??

our could it be another problem?

thnx for your help!!

Discussion / Observation

Battery is likely "just old" and needs to be replaced.

In spite of the lack of failure  message, 58% - if the charge is falling quickly , is not enough charge to handle the  full requirements of the computer.  Also, if the maximum charge is that same 58%, the battery is at least "weak".

Important Update: Expansion of the Battery Safety Recall and Replacement Program for HP Notebook Computers and Mobile Workstations announced in January 2018 – Additional Batteries Affected

HP urges customers to recheck all potentially affected products

In cooperation with various government regulatory agencies HP has announced an expansion of its worldwide voluntary safety recall and replacement program for certain notebook computer and mobile workstation batteries announced in January 2018. The potentially affected batteries may have been shipped with certain HP notebook computers and mobile workstations sold worldwide from December 2015 through April 2018.

The batteries have the potential to overheat, posing a fire and burn hazard to customers.  It is essential that you check or recheck your battery, even if you did so previously and were informed that it was not affected.

HP’s primary concern is for the safety of our customers. Because these batteries pose a fire and burn hazard, it is essential to visit the HP Battery Recall website at www.hp.com/go/batteryprogram2018 as soon as possible and check your battery.

Battery will not charge when system is warm to hot

If the “not charging” issue is (only) apparent when the system is running hot (or near that point), the battery and charge system are likely overheated as well – the charge system will resume operation when the computer cools down.  Short Version:  An overheated battery / computer / charging-system will not charge the battery – this is normal behavior.

Battery seems “stuck” in a particular charge setting         

The battery might be OK and just need calibration (balance / set).

The steps to check / calibrate / replace the battery are included in this document:

thank you for the respond!

i noticed that on the test the voltage of the 4th cell is 0V.

Isn't that worrying?

the battery does not qualify for the replacement program.

buying a new battery is the smartest idea?

with kind regards

You are welcome.

There is no "fourth" cell.

There are three sets of two-cells each in a six-cell battery.

What?

Easy to understand explanation contributed by  HP Retired member Steelers_81

The way battery cells are design is 2-cells are in parallel to each other, which looks like 1-cell. Since the Zbook 17 G3 is a 6-cell battery, it would have a total of 3 cells that have 2-cells in parallel. 

That is the reason why on the HP Battery check, it only shows 3 cells.  Depending on how the cells are placed, some units will have information on cell voltage 1 to 3.  Other will have cell voltage 2 to 4.

If a unit have 8-cell battery, then it will show cell voltage 1 to 4 on the HP Battery check.

Were it my computer, I would replace the battery.
