    HP 15 ab584tx thermal shutdown due to IC overheating

    Model: HP pavilion 15 ab584tx
    Issue: Thermal shutdown (Boot screen Error Code:90D)

    I did the initial cleaning and repasting, but it would still shut down. I managed to narrow down the problem to the IC APW8858 overheating. I had the IC replaced, but within a few hours, the new IC was short. The local technician I gave it to says it may be an inherent CPU/GPU issue and may need a motherboard replacement. I want to make sure that if this board can be resurrected or it is gone beyond repair.

    I'd appreciate any help or guidance on this issue. Thank you very much!

          no schematics available.. try to post all the power rail.. and alw.. maybe theres a short somewhere that is why IC APW8858 is overheating a power management ic.. hp15 with i7 6th gen pro. with built in graphics and separate nvdia bga graphics ic.. APW8858 powers the i7 processor.. focus there.. maybe a short mosfets .. i7 processor rarely fail but there is always an exemption .

              Laptop overheating after replacement thermal paste
              by Veyron7887
              Hi. I have Asus X55C laptop from year 2013. It has i3-2328M CPU. I replaced stock thermal paste with high quality thermal paste. Before thermal paste replacement, I measured CPU temperature Around 65-70 degrees Celcius with stock thermal paste. If after the replace thermal paste, I measured CPU temperature around 80-84 degrees Celcius and fan don't stop when system is idle. I replaced the thermal paste several times but still did not change. Where is the problem?

              MSI GP62MVR-7RF - weird fan / thermal issue
              by gurj1979
              Hey guys, I need help with my personal MSI GP62MVR-7RF. Annoying fan / thermal issue.
              Machine Idle. Fan will spin medium speed for 4 seconds, then off for 1 second. Repeat forever.
              CPU and GPU are cold. No load, just sitting doing nothing.
              It's clean inside, nothing blocked. New MX4 paste.
              Updated BIOS, EC, and VBIOS but nothing's helped.
              Schematic shows 2 thermal resistors, but they're OK.
              All thermal signals are good, inc PCH.

              Has anyone ever come across this ? Any idea what to do ?
              Could it be a faulty CPU / PCH / KBC ? I REALLY don't want...

              Samsung S22 plus reboots and heats up occassionally or after use
              by alltvrepairs
              Hi,

              I’ve noticed that my S22 occasionally freezes and shuts down—about once a day. I’ve already done a factory reset, installed only the essential apps, and updated the software. I also tried enabling power-saving mode to limit the CPU to 70%. This reduced the frequency, but the issue still occurs from time to time.

              When it shuts down, the casing becomes hot and stays that way. I then need to restart the phone by holding down Power and Volume Down.

              I’ve run diagnostics and enabled Developer tools to monitor CPU, GPU, and refresh rate. Unfortunately,...

              Dell Latitude 3510 Overheating & Fan Control Issue – Need Help
              by Ven
              Dell Latitude 3510 (Intel Core i7-10510U) CPU Overheating

              Issue Description:
              1. CPU Overheating to 100°C
                • When I start the laptop from a cold state, it takes about a minute to reach temps around 80-90-100°C, and CPU thermal throttling triggers.​
                • When the CPU fan is running at full speed (by disconnecting PWM and TACH cables), CPU temperature stays around 50-60°C.
                • However, when the fan is connected normally to the motherboard, it does not kick in at high temperatures.
                • I also noticed a few times that the fan kicked in for a very short time, but it does not stay on consistently.

              Yoga 530-14ARR NM-B781 Ryzen 3 2200 – overheating and shutting down under load
              by Maniackk
              Hi,

              I’ve got a stubborn patient here. The laptop powers on and works, all components like the screen, keyboard, touchpad, etc. are functional. The issue is that it heats up very quickly under load (within a few minutes up to 95°C) and then shuts down shortly after. Subsequent attempts to turn it back on right after a “hot shutdown” result in it shutting off within a few seconds. Interestingly, if I enter the BIOS, it can stay there for 2 days without shutting down (most likely due to low CPU load and low temperatures).

              The cooling system has been cleaned, thermal...
