PRECISION 5520 - System problem
Hello all
This issue is related to the Precision 5520 with an i7-7820 processor - the computer does not start up correctly.
- Virtually no operations can be performed on it, the reaction time from selecting, for example, the start menu to its launch is several minutes.
- The system date is set to year: 8522
- The date in the BIOS is correct, i.e. it is valid after logging into the system as above.
- The computer runs diagnostics without errors
- M2 SSD, SSD 2.5, RAM etc. have been replaced and checked
- The board was removed and connected directly to the monitor, unfortunately the problem remained
- The computer works fine with Linux (tested on Ubuntu / Fedora)
- The problem is not related to the Windows 10 media (checked on other computers), however, to be sure, a new Windows 11 media has been prepared (the problem is the same).
- BIOS updated, downgrade performed, upgrade - no effects.
Which component on the motherboard could be responsible for such a malfunction? (not a BIOS chip)
The problem concerns 8 pieces - the same model.

Hello Robert,
I recently bought my Dell Precision 5520 (i7-7700HQ/Nvidia Quadro M1200) and I noticed it was over heating at times especially the battery when being charged or playing a game on low settings. The Graphics card reaches up to 76C-77C which it is crazy and the fans running at full speed. Make sure you update the Bios to the latest version via Dell Support Assistant or manually on Dell Website, also There were recent updates to Graphics Card Drivers, Wifi, Bluetooth etc) which seems to help a bit but I never experienced any unexpected shutdowns due to overheating. There are issues with the fans blowing the hot air out in strange direction. Why Dell should have done, the hot air should escape towards the screen and upwards. I did clean the air vents and replaced the CPU/GPU Thermal paste, it helped a bit. I even changed the DDR4 Ram but the system won't take higher than 2400 MHZ, I installed Crucial 3200 MHZ 16GB and Crucial M.2 Nvme. I bought one 97W battery to replace the built in battery because it was over heating. If you tried to open the casing you will see the thermal copper glued to the casing. My advice to you, take it out completely because the thermal copper is blocking more than half of the air vents on the bottom which is the casing which is resulting the laptop heating even more than it should. This will allow air to circulate more into the motherboard, CPU and GPU. It is still good light laptop, I was surprised that you can play some games on low and medium settings which it was shocking for me. All new laptop especially gaming laptops overheats badly which can result in unexpected shutdowns. With new battery and other hardware, I am happy with my second laptop. I updated to Windows 11 x64 and yes it supported it but Dell refused to release any new drivers. All Drivers from Windows 10 x64 worked on Windows 11.
