HP Pavilion DM3-1000 Overheating

[AndyR123A]

I've had this laptop for 11 years but stopped using it after the 9th year because, it would always overheat and I didnt have money to buy new parts it would just shut down every 5 mins. Fast forward a year I'm in my Comptia+ class learning how to fix desktops/laptops, So I go back to my laptop to fix it got frustrated couldn't figure out how to open the laptop and left it alone. Fast forward to the present im in need of a basic laptop i've worked in the field as a technician I think I can fix this. So I take it completely apart and find out my power connector had been out of place fixed that. The fan was not working replaced the fan. Charger was not working at times replaced the charger, so now I think to myself should be good lets boot her up 10 mins later crash! The CPU overheated not really sure how to remove the CPU so I assume i'll buy a new motherboard and the processor will come with right ? Wrong! The seller informs me the processor is not included, but all my life I was taught you can't change processors from laptops so I guess my question is 1. How do I remove the processor, 2.What kind of processor fits into HP Pavilion DM3-1000 Intel Laptop Motherboard w/C2D SU7300 1.3Ghz CPU 584079-001, and 3. Should I just buy a new motherboard if this one has been sitting around for 11 years ? If anyone could offer me some advice that would be appreciated. Thank you, Hp user guy 68

@AndyR123A Welcome to HP Community!

I understand that you are facing the overheating issue.

Do not worry. I will try to fix the issue.

I have a few steps to resolve this issue:  

Symptoms of heat issues and causes of excessive heat  

The following list describes some of the issues caused by overheating in the notebook:  

• Games stop responding during play.  

• Windows stops responding during use.  

• Fans inside the notebook become louder because they are spinning faster as the laptop gets hot, to remove the heat.  

• When starting the laptop, it sometimes stops at a black screen and does not open into Windows. Windows usually stop responding when it does open.  

The following list describes some causes of excessive heat:  

• Dust inside the laptop.  

• A new component, such as a hard drive, is added. The extra component causes the power supply to work harder and generate more heat. Extra heat also radiates off the new component and adds to the temperature inside the case.  

• Over time, some cooling fans might slow down and wear out, as the laptop is getting hot, depending on the usage of the laptop.  

• High ambient room temperature.  

Step 1: Removing dust and lint by cleaning vents  

Step 2: Ensuring proper space for ventilation  

Step 3: Updating the BIOS  

Step 4: Using HP CoolSense technology  

Step 5: Placing the notebook in a cooler room  

Step 6: Testing for hardware failure  

If the hardware has failed, capture the failure ID and revert for further assistance.  

 
If the Fan is Noisy and Spins Constantly, PC is Warmer than Normal: Click here for more details. 

CPU is not a user-replaceable part.
