I have an Aspire A515-57-731E (Model N22C6) laptop that came with a 65 watt barrel jack charger. Laptop is I7 with Iris XE configuration. Under heavier workloads the charger gets extremely hot to the touch and fails to charge the battery at same time as powered on. Work's fine under lighter load.

After searching the Acer site it appears a 90 watt charger is available(P/N: ZL.Z01AA.00J). The question is will this help the issue? Will the laptop even be able to utilize the extra power or is it locked in at 65 watt? I know some manufactures lock in a specific max.

On a second note it appears the USB-C is locked in at a 65 watt max Power Delivery so that is a no go. Can this be confirmed? A USB-C charger would be cheaper but if locked at 65 watt no better.

Thanks!

    That 90W barrel plug power adapter (ZL.Z01AA.00J) will work fine but I am not sure if it has the correct 3.0x1.1mm pin that fits the barrel DC port of your laptop, the Acer shop just states "Blue tip". Instead consider using a 90-Watt USB-C charger, Thunderbolt supports up to 100 Watt and not limited to 65 Watt regardless of what guides imply. https://www.zdnet.com/article/best-usb-c-laptop-charger/ These are the barrel plug (brick) adapters recommended by Acer for your laptop:

    This is the adapter you are using now.


  • Note, that all charger adaptors have a cut off fuse if they overheat or there is a short in the laptop, as then the adaptor cuts off and disconnects and doesn't work, its the same with your laptop temp settings. Don't use any non oem power adaptors that acer dosent list for your laptop, as it could be a fire hazard and/or will damage your laptop.

    I've got the same laptop the model A515-57-56UV and I don't have that problem, my son plays heaps of games on it and abuses it no end and this laptop with its 16GB ram PCIe4x4 boot drive works perfectly.

    This is my A515-57 laptops 65W adaptor with its 1.1mm tip

    That is indeed the charger currently have. When entering the laptops serial number into the accessory finder the 90 watt shows up. Assuming compatibility based on the filters but you are correct it does not confirm the 3.0 x 1.1mm plug.

    I would much rather a USB-C on the Thunderbolt. The manual found at: https://www.bhphotovideo.com/lit_files/1016719.pdf only mentions USB-C charging for the A515-47 which is 65 watt. Only mentioned Thunderbolt 4 for the A515-57 which should do 100 watt but I know OEM's restrict that.

    Am using the OEM adapter provided with the laptop. Same one as you posted.

    The thermal cutoff has never enacted as always supply's power just gets extremely warm and seems insufficient for the job. Could just be a bad adapter as that does happen.

    Is indeed a decent gaming machine! Interesting how he uses it without charger issues. Never had had the machine shut off or overheat just the charger display these symptoms.

  • Yes, you might have a faulty adaptor, but most of these chargers do overheat on all laptops, the same happens on my Nitro 5 AN515-56 i7-11370H / RTX3050 gpu 32GB DDR4-3200MHz laptop that has an oem Chicony Power 135W 19.5V 1.7x5.5x11 adaptor and that heats up also, and this is supposed to be a high-end Acer gaming laptop that is made for gaming. Leave your adaptor like it is maybe get a 65W USB-C charger and use that as an alternative and test it out. Good luck and hope I've helped you out.

    This is the TBT4 USB-C specs of the left side port of the Aspire A515-57 laptop:

    Interesting that the same issue occurs. For a high end gaming, heck any gaming laptop it should be better matched & quality. A higher power draw is to be expected.

    I am going to try a 100 watt USB-C PD charger and see what happens. Worse that can happen is negotiates down to 65 watt. Can't work any worse then the OEM one.

    Thanks! Have helped a lot!

    The problem is the 1.1mm socket.
    I had to return the computer to after-sales service after 3 months. The contact between the socket and the plug was so poor that it caused overheating to the point of melting the plastic around the socket.
    wanting to pass 65w into such a small socket is not logical

    Yes, the barrel pin plug size is the most important item for a compatible adapter, yet this specification is often vague or omitted by online vendors either on purpose (sales pitch) or universal models. Never buy detachable multi-plug adapters. They sell small caliper tools (don't buy a plastic one but a professional stainless caliper) in good DIY shops and you can then measure the ID of your DC port and the diameter pinhole of your adapter plug before buying a new adapter.

    Wanted to provide an update for those in the future with potentially the same question.

    Everything is working great with a USB-C PD charger. No more heat nor charging issues. Would highly recommend.
