This issue has been going on for a few days now where the battery on my laptop will not charge. If the charger is plugged in the laptop works fine but stays at 0% for as long as I use it and will die if I unplug the charger. Does anyone have any advice for me before I take it to a shop? 

My laptop is an Acer Predator Helios 300 from about 4-5 years ago. I don't really know how to give any more Spec info but if someone can point me where to find it I'm happy to share if it can help me with this problem.

    (1) Search 'cmd' in Windows start menu.
    (2) Right click command prompt near top of menu.
    (3) Click run as administrator.
    (4) Enter 'powercfg /batteryreport' at command prompt.
    (5) Then return to the desktop. Open file explorer.
    (6) Then search for' battery-report.html' in the c:\windows\system32\ sub-folder. Double-click to open it in the browser.
    (7) Post screenshot of the first part of the report if possible that compares design full charge capacity with its remaining full charge capacity.

    Is this what you're looking for?

    Hasn't cycled. Further down the battery report you probably should see a steep drop off in battery charge level that started a few days ago. Can you also post a screenshot of that section of the report?

    Is this what you're looking for? There isn't any data from the last few days. 
    The left column is full charge capacity. The right column is design capacity

    Try this. Open Device Manager. Right click and uninstall all the battery drivers in the batteries folder. Then shut down Windows normally without resinstalling anything. Unplug the  charger. Gently insert and press a paperclip into the battery disconnect pinhole for about a minute. Plug the charger back in. If the battery charge LED is lit steady orange, wait till it turns steady blue before powering up. If unlit while turned off, report back.

    It did turn a steady orange when I put the charger back in and I left it for the past couple of hours. But when I just came back to it it was still orange. When turned on it still displayed 0%. Any other advice? Thank you very much for your help with this so far.

    This suggests the battery's own internal charge controller has failed for some reason. It may not be  recoverable. Shut the laptop off again. Keep it plugged in. Wait at least 24 hours to see if the steady orange LED finally turns to steady blue. If it still doesn't turn steady blue after 24 hours, then you probably should replace the  battery. New replacements should cost about $40usd for the PH315 series.

    Ok. Thank you very much for your help and advice with this all. 
  • It would also be interesting to confirm the battery wear, with the hwinfo64 program, in the smartbattery tab.

    @egydiocoelho Agreed. The wear level seems too low for a battery that old. Another indication that the battery's own internal charge monitor may have gone bad.
