r/AcerNitro

I have an Acer Nitro AN515-58 with an i5-12450H and RTX 4060. While playing GTA RP, my CPU temperature stays around 90°C and the GPU around 70°C. I’ve already cleaned the fans and replaced the thermal paste. Is there any way to improve these temperatures?

**TL;DR:** My Acer Nitro 5 started flickering LEDs and beeping on boot after 2 years. Turned out the stock 230W adapter was degraded. Replaced it with the 280W OEM unit. Problem gone. But here's the thing — it probably shouldn't have been 230W in the first place.

## The symptom

One day my laptop started doing something weird on startup: both LEDs would flicker, a short beep would sound (like the charger got unplugged), and the network card wouldn't initialize. Unplugging the adapter from the wall and plugging it back in usually fixed it — but not always on the first try.

During actual use? Perfectly fine. Games, heavy loads, long sessions — no issues whatsoever. Only on cold boot.

Wiggling the DC jack did nothing. The click-lock connector felt solid. No signs of physical damage.

## The diagnosis

The cold boot behavior was the key clue. When a laptop powers on, it draws a spike of current during POST. If the adapter can't handle that spike — voltage drops, and the system interprets it as "charger disconnected."

Why would a 2-year-old OEM adapter suddenly struggle? Because electrolytic capacitors inside power bricks degrade over time, especially if the unit runs hot regularly. And mine ran hot. A lot.

Which brings us to the real problem.

## Why the stock 230W adapter was always the wrong choice

My colleague has a Nitro 5 too — i5 10th gen, RTX 3050. Same 230W adapter. His runs fine.

Mine has an i7-12650H and RTX 4050. Also 230W.

The i7-12650H has a higher TDP than the i5 10th gen. The RTX 4050 draws more than the 3050. Combined peak consumption on my config can approach — and briefly exceed — 200W under full load. That leaves the 230W adapter with almost no headroom.

Running a power supply near its maximum rated output continuously causes two things:

- It runs hotter

- Its capacitors age faster

Acer's service manual actually lists 280W as an official adapter option for the AN515-58. The part exists. They just didn't ship it with i7/RTX 4050 configurations. Whether that's a cost-cutting decision or an oversight in the product spec sheet — you decide.

## The fix

Replaced the stock Delta ADP-230JB D (230W) with the OEM Chicony A21-280P1A (280W).

Part numbers to look for: **KP.28001.001** or **KP.2800H.001**

Same 19.5V, same 5.5×1.7mm locking connector with the click. Drop-in replacement.

Result:

- Zero boot issues since

- Adapter runs at ~40°C under load vs noticeably hotter before

- Working well within its rated capacity now (~65-70% load instead of 85-90%)

## What you should check

If you have an **AN515-58 with i7-12650H** (or any higher-TDP variant of this laptop):

1. Check your adapter model — if it's 230W, it's undersized for your config

2. If you're experiencing intermittent boot issues, LED flickering, or single beep on startup — your adapter is likely degrading

3. Don't just replace it with another 230W unit. You'll be back in the same situation in 12-18 months

4. Get the 280W OEM (KP.28001.001) — it's the right spec for this hardware

The 230W might work fine for lighter Nitro 5 configs (i5, RTX 3050). But if you're running the heavier silicon, your charger has been quietly suffering since day one.

P.S. I apologize, English is not my native language, so I used technical means to be understandable and more people could solve their similar problem to mine.

This were the updates I did recently and now it's like when I turn off charging button it shuts down , sometimes it works all ok , sometimes does wierd shit like this idk wt to do !! Help guys

Am i cooked? Need assistance, tried every possible diagnosis on internet i think the ones people say when it doesnt turn on.

It suddenly turned off and didn't turned on when i was using browsers editing a report online.

The lights were off yet until now both charging or power on, but i think i have some hope here

(It did started once and i used it gradually increasing stress like gaming in end nothing was wrong until then) Later i shut it down at night normally, and again in morning it didnt turned on.

So if it started once or twice, that means it isn't died right?

As much i think its not a mobo problem but give some advice urgently in need, and not in warranty. (Been 2.5 years now).

If you guys Need more info to troubleshoot then just please ask.

A guy said it will be 8k in inr then he gone to 4k inr slowly convinving me saying its an ic issue on mobo etc. thanks you community please help!

My Acer Nitro 16 is out of warranty. I called a few places and they said Liquid Metal is risky and they prefer normal grease even if it was their pc. Some places dont even have em. Im wondering, is it really necessary? Can i just use normal grease? What would change

Its not in other drop down boxes as well

My resident evil requim is constantly crashing, any fix?

Is that the CPU or GPU fan? Got it from the market and found out this one was replaced by a random ahh fan thats apparently useless although it runs on 6000+ rpm. Need to replace it with an ORG one.

I normally don't ask this since I'm used to this, have been since 2023 or so but I've grown tired of it.

The model is a AN515-51, I've used notebook fancontrol as well, but it doesnt do any difference. Why could this be? I just cleaned the lap half an hour ago
