Battery drops & charger overheats?

Axiond · January 2018

Hello all,

I just bougth this laptop (PREDATOR PH317-51) for 3 days and my battery drops 1% every 2 min (not plugged in) although I switch the battery saver mode on, put the brightness to the lowest - I don't do any heavy task either; just normal browsing, etc.

Today I also have just noticed that the charger overheated (trust me, you can make a pancake on it) and this started after I installed ThrottleStop.

Do I need to get the battery replaced or is there something else I can do to fix this?

Please advise

Thank you very much in advance!

Hi,
Try a battery reset, switch off the laptop, disconnect from mains(remove AC adapter), follow the instructions in the video, once completed leave the laptop to rest for 15-20 Mins before starting again.

Hi,
No problem, it could be a faulty charger( manufacturing fault), if the battery reset doesn't help you may have to get in touch with Acer support and explain the problem, they may send you a replacement charger.
BTW, I forgot to mention to reinstall Microsoft ACPI- Compliant control Method Battery driver as well in Device manager. Uninstall the driver, reboot and let Windows install the driver.

Hi Brummyfan2,

Thank you for responding.
I will update you ASAP

About the overheated charger, do you think it's caused by the battery or throttlestop?
it was just a bit hot before I installed & configured TS.

I'm not sure if I want to uninstall TS as it significantly decrease my laptop temperature.

I have done everything but the battery still drains very fast (22% in less than an hour and it's on the max battery saver mode)

is it normal?

I will update on the charger as soon as I can

anyhow, thank you

Hi brummyfan2,

Just want to update you on this:

1. The charger doesn't overheat anymore.
2. Max Temp. 75 - 76c under heavy load - auto fan & cool boost mode ON (ThrottleStop is definitely the best for this laptop)

Battery is a bit better but still disappointing overall

I need a suggestion though; should I remove the battery instead (for longer battery life?) as I don't really move around much with it?

oh and one more thing, do you think I should repaste the CPU & GPU for better temp. and performance?
if so, how lower would I get by doing it?

Thank you

Hi,
Please follow the instructions for manually calibrating the battery in the link below, monitor the performance after few cycles, as for the temps, 70-75C under load is not bad at all, so you don't need repasting, if it goes to 85-90 then you need to consider repasting.
