CB715-1W-30JY Acer Chromebook C715 not charging

andrei172747

my chromebook isnt charging and the original charger isnt working, when i try charging with a phone cable(keep in mind the chromebook has type c charging port) the red light stays on for a bit then it starts flashing, can someone please help me?

[Edited the thread to add model name to the title]

I don't find any reference for a C715 model, could it be a CB715? Your full model number is usually on the same sticker as your serial number, it should look something like xxxxx-xxx-xxxx. Typically laptops need more power than a phone charger can provide.

so, I am updating my problem a bit, the original charger isn't working with the laptop but it is working with other devices such as my earbuds or a different phone, the only way I can charge this laptop at the moment is by using 2 type c charging cables and that is still not enough, the original charger is working but not with the laptop for some reason

So I have found on my USB-C charged laptops that the plug needs to have just a little bit of tension when in the socket to get good contact. I do that by giving it a half twist when it's plugged in. Your system wants 45W of charging, and the phone type chargers are typically 10-15W, so that would make sense that you need two of them to do much of anything. Try using the stock charger with a twist on the cable to see if that helps.

also the same issue as with the old one

billsey

I assume you have tested on both sides? There almost has to be something wrong with the charging circuit, except that you said you could charge by connecting two phone chargers… I'm stumped.

maybe its the laptop not accepting the required amount of wattage? last time I charged the laptop with the original charger was 1 month ago and it still didnt charge correctly, before i charged it that time no ports were working as well and idk what i did to make it work tbh lol

billsey

I can't image any scenario where it would accept a 10W or 15W charge, but not a 45W, 65W or 100W charge. I admit I'm not deep into charging circuits, but… I wonder if it might be a voltage thing? The stock charger, and any charger that outputs enough current, is going to do it at 20V, the phone chargers are at 5V.

the new charger is the same as the old one in terms of amperage, voltage and wattage and it still doesnt work

billsey

That's kind of what I'm trying to say… Any charger that meets spec is going to provide 20V@2.25A or higher. The phone chargers that seem to be working, albeit slowly and doubled up, provide only 5V. That seems to be the biggest difference between the two. If there were something wrong in the charging circuit that, for instance, tripped a internal breaker at 7V, the 5V chargers would do something, the 20V chargers would do nothing.
