Greetings,

I had a problem with Acer Nitro 5 some time ago and i'm sure now the problem is the charger. I need to buy a new one but I have a question about the specification:

The original charger have 135w, 6,92A and 19.5V

I can only find acer charges now with these specs: 135w, 7,1A and 19v

I'll have problems with this new one? The new one has 0,5V less voltage.

Thanks!

    Hi @Craios

    They all seem to have 7.1 amp and 19V DC (Amazon), should be OK, 135w is the correct capacity.

    Hi again!

    Thanks for your answer. I decided to buy this model with 7.1 and 19v with 135w. Some strange thins happened at the beginning, like the amber light that indicates if the notebook is charging was blinking.

    Now it charged completely but I noticed that the notebook is warming a little too much. When i'm playing games the temperature was at 95°c. That temperature is normal in a Nitro 5? There is something that I can do about this? Like change the thermal paste or anything like that?

    Thanks in advance!

    Have you cleaned your fans recently? Also check your battery condition (amber light?) by creating a Battery Report in Windows; check what the Full Charge Capacity does over the last 3 days (should be the same) and how it compares with the Designed Charge Capacity. If you decide to replace also your battery ($40) you should clean the fan outlet (while the battery cable is disconnected!) and heat sink inlets as there is a dust trap that may be blocked by lint and dust, you need to remove the fans to access and clean that properly. Never play big games on battery only, always have the power adapter plugged in.

    Hi @Puraw

    I cleaned one time, but I'll do this again. The amber light I refer is light indicator of when the charger is connected. It's an orange light I suppose that turns into blue light when it's fully charged.

    I checked the battery condition with the "acer care" software. It said it was fine, no problems ocurred.

    I noted something that might be the problem:

    • The new charger I bought said the connector's size is 5.5mm x 1.7m.m. I didn't find in the manual in acer's website what is the connector size especifically, but I suppose is this one. The connector connect with my notebook, it's charging normally, but I noticed that connector is slightly higher than my original one. higher enough to not make that second click it was supposed to do when we connect the charger.

    Sorry if I write that much, I really dont know if I should give back the charger and buy another one. The notebook seems to be working fine, just this warming that I don't know if it's normal.

    UPDATE

    I cleaned the fans and the performance of the temperature is way better. I mean, it still reaches 90ºc but the notebook isn't warming up anymore.

    There is a way to check if the charger is delivering the expected voltage? The charger is 19V, how do I check if it's really at that voltage?

    Thank you again!

    I worry a bit about the tip size of your power adapter plug. Color, length of the barrel and the inside of the pin should be exactly identical to the original tip. I use a caliper tool (hardware store, small plastic one is cheap but works OK) and I always check that: You should get a positive click when you fully inset the adapter plug in the laptop port and it should be a perfect fit (no wobbling of the plug when you move the laptop and the plug should go in slick without any effort). Use the Windows Battery Report instead of Acer Care (I have uninstalled Acer Care) type/paste the following in the Command Prompt:

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

    Important is the Full Charge Capacity over the last 3 days and if that stays steady (should be the same as the Initial Full Charge (zero change over at least 6 months). Always less than the Designed Capacity which is just an inflated number quoted by the vendor. If it shows higher you need to "train" your new battery by draining it to 10% charge and let it charge to 100%.

    On the adapter output DC voltage: BIOS will state "AC power adapter wattage and type cannot be determined" when the voltage is not compatible, other than that is the old Multimeter to check the voltage, I have a (Chinese imitation) Fluke and use it regularly for everything in the house. No Windows software to check adapter voltage (Linux got it) but the Full Charge Capacity would not show 100% if the voltage is too low.
