As laptop batteries age, they may start to misreport their information to the computer, causing the Puppy battery monitor to fail.

Batterup is a very simple replacement that will keep working. It displays the time remaining until shutdown and pops up a warning message when the battery is getting low.

Please note:
1.The Batterup tray icon does NOT change its appearance with the status of the battery.
2. It will start to show the time remaining AFTER you unplug the charger and the battery begins to discharge.
3. If you need an icon to tell you if your charger is plugged in, this tool is not for you.
4. Your laptop has an LED indicator that tells you when the battery is fully charged. If you need a tray icon to tell you the same thing, this tool is not for you.

Anyone who wants to try Batterup should send me a PM.

--------------------------------

The default warning time is 10 minutes, but you can easily change it.

1. Go to the folder /root/Startup
2. Open the file batterup_start in a text editor.
3. Line 3 is:
Code:
WARNTIME=10   # minutes from shutdown

4. Change the 10 to whatever time you want.
5. Run Utility > Batterup Restart

-----------------------------

Update: If the warning message pops up while the machine is unattended, it will stay up for two minutes. If no action is taken during that time, the machine will power down.

-----------------------------

Update: Batterup uses two methods for triggering a warning. The primary method is to estimate the time remaining in minutes. But some batteries cannot provide the information required to make that calculation. Then the fallback method is to compare the remaining charge to the battery's own "design capacity warning" value.

But some batteries also fail to provide that information reliably. So here is a third method. It uses the battery voltage as an indicator because voltage tends to drop as batteries discharge. This has been confirmed to work by Don604.

Open /usr/sbin/batterup in a text editor and find line 51.
Code:
WARNCAP=$(grep "design capacity warning:" $BATPATH/info | awk '{print $4}')

Delete it and insert these lines.
Code:
UNITS="mV"
WARNCAP="10000"
REMCAP=$(grep "present voltage:" $BATPATH/state | awk '{print $3}')

This will take some trial and error. Adjust the "10000" to get a good warning point for your battery.

looks neat...quick test on 4.12 was fine so nice an compatible.

One feature I noticed is its easy to alter where it gets the battery info from...I had to make a custom vattery for one persons machine.

Thanks for testing this.

When working with zaivala here, I discovered that some batteries report their data in mWh instead of mAh. I believe that Batterup should also work with these batteries, but it has not been verified.

If you have access to this type of battery, could you please test it?

Well as it happens this notebook does use mwh.... incorrectly (it actually should be mAh) but the time remaining is correct. And yes its a battery in a poor state...gets 25 minutes max Smile...so perhaps a good test.

I like the flexible wrapper/config

Thanks. Since P=VI, I was pretty sure that it would work.

You'd said

Update: Batterup uses the battery's present rate of discharge to calculate the time remaining. But some batteries do not report this information. In that case, v1.4 displays the amount of charge remaining in mAh or mWh and triggers a warning message when the charge drops below the battery's design capacity warning level.

I just installed ver 1.4 on this Dell Latitude E6410, Lucid Puppy "Super 2".
Hovering over the yellow icon shows
Quote:
Battery BAT0: stopped charging
Does that seem OK?

Thanks,
Sheldon

Is the AC currently plugged in? That message appears when Batterup checks the "charging state" of the battery and gets the report "charged". That means that the battery is not currently discharging. Batterup needs to see the battery discharging in order to determine how much time is left.

OK, I unplugged the charger.. AHA! Now it says

BAT0: 152 minutes left

Excellent. Now you need to experiment a bit. You currently have 152 minutes, based on your CURRENT rate of discharge. If you start watching a video, your discharge rate will increase and your remaining time will decrease quickly. So the default warning time of 10 minutes may not give you enough time to shut down before the battery dies. I originally had it set at 5 minutes but it sometimes wasn't enough if the discharge rate suddenly jumped.

Excellent will try with 3.01 and AnitaOS based on Mikeb's report will be excellent if it reports a true reading, great work thanks.

No reply? There has been almost no feedback on this project. If it has no practical value, I will remove it.
