FX eating battery while sleeping

Hi all,

I got my P-172X FX and since then I have been putting it to sleep unplugged every night. I've always went to bed with the battery at 99 or 100% and woken up with it at about 93 or 94%. However, starting 3 days ago, I wake up and my battery is down to the last 10%. Indeed, one of the days it actually shut down because the battery ran dead. Last night I made sure to watch the computer before shutting the screen to make sure it didn't freeze before sleeping and the process went fine, as far as I could tell. However, I woke up this morning and the battery status was red.

I haven't installed anything new or added any new hardware (I added speakers about a week ago but those have their own power supply). Does anyone have any idea why my laptop would be doing this?

Thanks,

Dan

 

The best thing for you to do would be to check event viewer (start>right click computer>manage> click event viewer). My best guess is that you'll probably see something related to windows update occuring at 3AM, which I think is default for windows update. I've seen reports that say that when there are updates pending, even when the computer is hibernating!, that the computer will wake up and try to install them. This might not be the case, but checking event viewer is the first thing I would do regardless. Let us know what you find. If it is windows update, simply set it to go active at a different time than 3AM, or set it to manual updates.

P.S. pretty smart with the unplugged battery at night (to preserve battery lifespan I presume). I think I'll start doing that.

 

Jakamo,

You're right; it did wake up and install updates last night. It didn't do so the night before however. I changed the settings and I'll see what the battery status is like tomorrow morning and let you know. Thanks for your help.

 

If the updates aren't the culprit you might have a battery that has reached its charge/discharge life cycle and is dieing.

If i remember correctly our batteries only have about 350ish charge cycles before they start deteriorating pretty hard.

I hope its just the updates though that's an easy and free fix

 

try disable "wake on" features

 

I set the automatic updates to "manual" and last night it went back to only losing about 6% charge. Thanks very much for your help, Jakamo. I would never have guessed that it was the updates!

 

no problemo

 

Could also be Windows Search re-indexing your drives and/or superfetch doing its thing.
