Hi, I bought my acer swift 5 back in March but almost every time I charge my laptop, the left side of the laptop (nearer to the plug) will heat. It can heat up to a point that touching it can be quite painful. I tried to get it fixed but they only cleaned the fan but the overheating problem persists. The laptop cools down maybe an hour after the charging begins but for that hour, I'm afraid that I'm causing more issues for my laptop. 

If anyone knows how to fix the issue or anything regarding it, please help!

Thank you so much!!

    It could be normal, or normal-ish, I don't know the specifics for your laptop nor do I have access to its schematics, but if that's the area where the voltage regulators are placed it would explain the heat.

    Simplifying things a bit, the AC adapter outputs power at 19v most likely, but even the battery of the system doesn't work at that voltage, it works at less, say... 15v, and the rest of the components work at a myriad of voltages, from 5v lines of the USBs to 3.3v, 1.2v maybe for the RAM, etc.

    VRMs, or voltage regulators, are a set of components in charge of converting and smoothing voltages so that they're stable, but that conversion is never 100% efficient, there are losses in form of heat. You've surely experienced something similar with your phone when it's charging, specially when you use any kind of fast charging technology because voltage has to be converted to appropriate level for the battery.

    And that is also the reason why a 5000mAh powerbank won't fully charge a phone if it had a 5000mAh battery, because there are conversions all around. From the battery of the powerbank which works at 3.7v for example to 5v or more which is what the USB interface outputs, and then back to 3.7v for the phone battery. Very crude explanation, but yeah, none of that is 100% efficient (somewhere around 80% maybe? depends on the quality).

    But I digress, the thing is that it may be normal if the area where the power regulators in your laptop lay nearby the power port, or not, if they don't. I'm afraid I can't give you a better answer, maybe someone from ACE if they have access to the schematics could tell you if it is normal or not. Or other members with the same laptop ;)

    I use an ACER Swift 5 (SF514-54T) since last Winter. Now with warmer weather I have really big problems as well, because the cooling system is not powerfull enough. In short terms the CPU cores are getting hot at 98 Celsius and device is switching off by itself. So it seams to be a design problem.

    Acer BIOS team need to fixing their PL2 duration via update microcode to 00000096 DATE 2020-06-16


    The 00000096 microcode allow long time Max turbo power time as upper chart by Intel. It will maximize Icelake U performance
    better than exist 00000032 microcode on lastest BIOS which allow only tiny time on PL2 mode as AIDA64 detect their setting up
    via Acer lastest BIOS below.



    As you see , Acer BIOS team only allow 2.44ms for PL2 mode compare to 18 second on It design provide by Intel. ;)

    That's unrelated @R6E7980XE, it at all staying longer in a higher consumption state would make the thing produce more heat and not less.

    Besides, careful with newer microcode updates, they can surely make things better by incorporating fixes or mitigations for security vulnerabilities but if you're looking to modifying PL limits (which are unrelated to the microcode itself) you may find yourself unable to do so if you run a recent enough revision.

    That seems unrelated to the problem the original poster was detailing too, your problem for example will certainly improve by opening up the computer and replacing the thermal paste that is interfacing the dies with the cooling solution by a high performance aftermarket one and cleaning the fan(s) heatsink if there is dust accumulated.

    It was standard design of the processor. However OEM can use their microcode revision by their choice mate.
    Just like you see the LPDDR4 4266 on my Swift 5 one. The specification of LPDDR4 was 4266 MT/s however Acer BIOS team
    setting its speed to 2666MHz below it specification. It can running but not fully performance of its spec above.

    The PL2 tau design by Intel for those chart above but OEM may selecting the time period by the BIOS for their purpose.
    If they use maximum PL2 period from Intel specification they will deal with short battery life problem.

    Sunny Cove Microarchitect had more headroom than Skylake on power management mate. But look like Acer focus on
    longest battery life instead of performace compare to other brand. :3

    Again, unrelated to @Anisa's issue.

    I very much doubt a manufacturer would go to the trouble of soldering memory chips to the motherboard capable of 4266 MT/s (which on itself is different from MHz/s) and elect to downclock them if the memory controller of the processor would support it (which on itself has little to do with PL limits). LPDDR4(x) doesn't behave the same as DDR4 sticks.

    But I will not stray further from the initial point of the thread: whether it is normal or not to for the side next to the power connector to warm up when it is connected for charging.

    I urge further replies to keep on topic, for the benefit of the original poster and anyone else with the same doubt that stumbles upon this thread.

    Overheat issues from original post can be address via Acer service nearby their resident if need.
    The service guy maybe re-paste thermal on the laptop. 

    But they're not overall fixing if Acer BIOS team not working for my reported issue about CPU and GPU.
    Hope they'll release news BIOS like ASUS team soon. :3

    Hi, I'm facing the same issue too. Have you found a fix? Can you check if the vent on the left side of your laptop (just in front of the screen) has holes in it? I noticed that on my laptop only the right side vents actually have holes, hence allowing air to move out. Is it the same for yours as well?

    Fan and holes in the left side no matter anything. You both have problems with charging plug. Check picture bellow.

    With throttlestop you can do this, ACER did nothing. All problems is in bad cooling system...... on my sf514-53t i have 2.9 GHz on all 4 cores, and temps ~77 C.

    Any idea how to fix this issue? Should I buy a new charger? Or is it a problem with the laptop itself?

    Same issue here. 
    I have tried all the driver option, power management options.

    It also has the latest bios.

    Power socket is fine, tested with a multi meter.
    Booted with a live Zorin linux and also tried another SSD and installed Zorin and using it ON and OFF the laptop charger is fine.

    This is what I have found.

    Off the charger with the laptop set to NOT sleep, Hibernation turned off.

    Display on both battery and mains is set to go off after 5 mins.

    Just on the battery the display goes off, the laptop goes quiet and then I am able to press the keyboard after 5, 15, 45mins or 1 hour and the Display comes straight back on.

    On the charger after 5 mins the screen will go off but then after roughly 10 mins I can here the fan ramping up.

    The hot spot near the charger is the heat pipe near the fan but what starts to get really hot is the surface mount ram, very hot.

    At this point if I press the keyboard its lights come on but the screen stays dark.

    At this point its locked up and the going through a thermal run away.

    The charger has to be in before the screen goes off for this to happen. 

    If I let the screen go off then plug in the charger it will just sit there until I press the keyboard after which it comes back on.

    Remember there is no Hibernation and its not Sleeping it is just turning off the screen.

    I am guessing some sort of power management issue with the Intel uhd 650 video driver is the problem. 

    Annoying,  thinking of just putting Zorin Linux back on as it runs really well on this hardware.

    When you plug the charger in while your laptop is on, the CPU fan works fine but once you close the lid without switching off your laptop and open the lid again. The fan does not start. I tried to update the bios for this issue. But when I checked their website I saw that the latest bios version is 1.18 and the bios that I have on the laptop ( one which is installed when I bought it ) is have version 1.21😐.

    1.21 is a EFI update pushed out in Windows Update, there are no changes to the ROM portion from 1.18. You likely also should be asking a question on your own thread instead of camping on this old one.

    Sorry for bumping an old thread, as this post is quite searchable from Google and I hope I could help other owners as well. I have found a possible solution, which modifies the sleep state of the device. Solution is at end of post, here's the explanation:

    When a computer sleeps, there are multiple states it can fall to. Traditionally, sleep refers to S3 state. Newer computers, including my unit (SF514-55TA), implement a new state called S0, or as Microsoft refers by Modern Standby / Connected Standby.

    The advantage of S0 is that resuming from sleep, is almost instantaneous when compared to S3. However, S0 sleep implementation has been known to causes issues with drivers not responding after waking up from sleep. There are plenty of examples online if you Google 'Modern Standby issues'. My unit, has a similar problem, where the fan does not turn on after waking up from S0 sleep. 

    The solution, which I refered to a reddit post here : Getting back S3 sleep and disabling modern standby under Windows 10 >=2004 : Dell (reddit.com), is to revert to the traditional sleep state of S3 rather than S0.
    Open cmd.exe as admin and run:
    reg add HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0

    To remove the tweak, you can just run regedit as admin and delete PlatformAoAcOverride under HKLM\System\CurrentControlSet\Control\Power again to revert back.
    Or just as admin in cmd.exe:
    reg delete  "HKLM\System\CurrentControlSet\Control\Power" /v PlatformAoAcOverride
    The side effect of this is that the wake on lid open function, from sleep, is no longer working. In order to wake the laptop, you would have to hold the power button until keyboard backlight comes up
