    AC Adapter or Faulty Battery?


    Hi there!

    Well, after what it seem to be like my triumph against sudden reboots (probably I just needed to fasten some screws to get all in order) I have a little doubt, since always, I noticed that my laptop battery tends to "discharge" when I do extensive tasks, name it doing video encoding or streaming with the GPU encoder. In any case, seems like it discharges, and tries to charge back, but at a very slow rate, all of this, using the AC adapter.

    I seldom use the battery as I'm always working on home, and plugged, but this obvious discharge cycles are wearing the battery (32% according to AIDA64).

    I've been told in Acer forums that probably the AC adapter is not enough to keep up with giving power to the PC and keeping the charge of the battery, it's a 45 Watt AC charger, the original taht came with this PC, then I was told that in some parts this laptop was sold with the "for gamers" tag (It's a fast hardware, no doubt, but for gamers?... dunno) and this particular, while being the same model, had a 65 watt AC adapter instead of this one.

    Now, the guy, very kindly, recommended me to better look for the 65 watt adapter, so this doesn't happen...

    What I would want to know is if, this actually is because of the AC adapter, or because the battery is either faulty or temps (this last is kinda unlikely, it's strange but, when streaming, I don't notice any super high temps, it maxes to 65 C at most, sometimes is even less...)

    In either case, I'm already hunting for a 64 watt charger and a replacement battery in case this one dies, but I wanted to still check with you in case I'm missing something here...

    The laptop in question is an Aspire E5-553-1786, APU AMD A12 9700P, Radeon R7 (512 MB), a new HGST 1 TB 7200 RPM spinner, and... pretty much that is XD.

    Thanks in advance for any comments.

    Cya!

    A 45W power adapter does seem a bit weak for that machine. Acer Aspire E5-553G-109A Notebook Review - NotebookCheck.net Reviews shows a similar laptop from that model (same CPU but faster graphics) pulling 63W at max load.

    Do you have a Kill-a-Watt or similar power meter? That way you can confirm how much power you are actually pulling from the wall.

    You can also try HWiNFO (HWiNFO - Download) to see if it can get the charge/discharge rate of your battery (a negative charge rate means that you are draining the battery).

    Run this command to get a battery report file which will be output to your desktop. The report might indicate your battery is due for replacement.

    powercfg /batteryreport /output %USERPROFILE%\Desktop\battery_report.html /Duration 10

    Hi guys! Thank you for the answers!

    @PolarNettles: When the described problem happens, it doesn't show a negative discharge rate, but just goes down to, lets say 95 percent and tries to charge from there, but ver, very slowly (even stating that will take 30 mins or even 1 and a half hours to charge 5 %) and the charge rate is very very low.

    @Steve C: I attach my report here, according to AIDA64 the wear level is 32% more or less, It used to be that last year, but I calibrated the thing manually and reseted that score, but is now again at that wear level, which I can't assume is accurate, but shows some unnecessary stress to the battery...

    Thanks for the answers guys!

    Does the slow charging only happen at high charge levels? What is the charge rate at, say, 50%?

    Never tried leaving the batt at 50% I'll see if I get the chance to try.

    First, it has to be said that the Output voltage of the new charger must match the Output voltage of the old charger or damage can be done to the laptop.
    After that, a higher wattage charger will charge any battery faster, not just a problem one. If the charger were the problem than any correct voltage charger will solve it, but a larger one is better regardless.

    Lithion Ion Batteries have a lifespan measured in recharge cycles. When a battery approaches the end of life it discharges faster, takes longer to charge, and may not take a full charge. Sound familiar?

    If the battery is more than a couple years old than that would clinch it for me.

    Thanks again for the answers!

    First I tried using the batt at 50%, does the same thing when in full loads, charges very veeeeery slowly, doesn't loose charge because it's already on a non full state...

    About the charger, I've been told about replacement parts on Acer, the charger they recommend (in their forums at least) is one that has 3.42 A and 19 V (I assume this can't harm the laptop... unless I'm told the contrary)

    On the other side, I'm seeking to replace the battery as well (when this one dies), they have two 4 cell models, one from Panasonic and One from Samsung, and I wonder which one would be good to pick (Currenty, this one is Panasonic, and I'm believing this came with some sort of damage from the fabric, since it always behaved like that, and has just 1 and half year...)

    Thanks again for your answers, and sorry for being absent so long, job is hectic for me nowadays.

    Cya!

    Look on the back of your current, OEM, charger.
    What does it say for Output Voltage?

    It says 19 V 2.47 A, which gives 45 W, rounded up :P
