The US Department of Energy has approved an $8.6 million grant that will allow the nation’s first utility-led geothermal heating and cooling network to double in size.

Gas and electric utility Eversource Energy completed the first phase of its geothermal network in Framingham, Massachusetts, in 2024. Eversource is a co-recipient of the award along with the city of Framingham and HEET, a Boston-based nonprofit that focuses on geothermal energy and is the lead recipient of the funding.

Geothermal networks are widely considered among the most energy-efficient ways to heat and cool buildings. The federal money will allow Eversource to add approximately 140 new customers to the Framingham network and fund research to monitor the system’s performance.

I stumbled on PTM7950 listing on AliExpress and thought to try it out. My Laptops and PC were working fine in my opinion until I checked out that I had the following Temps :

Relevant PC Specs :
CPU – AMD Ryzen 9 3900X 12-Core Processor [CPU Max : 83 ]
GPU – AMD Radeon RX 5700 XT [GPU Max : 89 / Hot Spot 100]
Laptop Specs [Asus M16]:
CPU – 11th Gen Intel Core i9-11900H [CPU Max : 100]
GPU – NVIDIA GeForce RTX 3060 Laptop GPU [GPU Max : 75 / Hotspot 80]

Decision to Use PTM7950

The above mentioned temps on PC GPU and Laptop CPU made it clear to me that I need to apply PTM7950 and I while the process of repasting of PTM on GPU for PC was very uneventful.

Things were bit different for the Asus Zephyrus M16. I could always respread the LM , but didn’t because the way it was spread all over the place and as I already opened the machine up , thought to apply PTM on both CPU and GPU.

While opening was relatively straight forward, I did get a surprise of Liquid Metal on the CPU , cleaning the LM was cumbersome, cleaned it up carefully and to the best of my ability.

After closing up the laptop and turning the power button I was presented with :

• Blank Screen / No POST
• Power light constant ON
• Battery light would blink twice and then give a gap and repeat
• Keyboard backlit in red
• Fans not spinning

I started googling and searching and the unanimous reddit verdict on such a condition was “LM is conductive and you didn’t do a good job and it has fried the circuits” a.k.a Motherboard dead.

Additional Remedies

Going to page 2 and 3 of google (indicates how desperate I was) revealed more ways to find out the problem, none worked, but it included:

• Removing the battery, pressing the power button for 45-60 second and connecting battery again before trying
• Drain it’s battery and then turn it on
• Let it run for 10 minutes
• Connect adapter and then turn it on after doing a power reset
• Ensuring the display cable didn’t break or is properly seated and connecting external display [but as the system was not POST so never tried that]

While I gave up thinking the motherboard is fried, One YouTube video mentioned that the Error code of “battery light blinking twice and then repeating after gap” means a corrupt bios and you will need to remove the bios chip and put it in a programmer to get it sorted (video did not show where is the bios chip)

Hope and Revival of Asus Zephyrus M16

The above mentioned video made me think maybe it’s not a dead motherboard. While the method which I tried (and worked for me) was mentioned in different asus related queries but not with something where fans wouldn’t work and the keyboard would be red lit.

How It Was Revived

You can follow the steps mentioned below to get your laptop back to working if you are facing similar symptoms:-

1. Open up the back case
2. Remove the battery connecter
3. Press power button for 10 odd seconds
4. Remove Ram
5. Connect battery connecter
6. Rest the laptop on its screen with keyboard in the air, and press the power button
7. Laptop did POST and went to windows [a bit slow as running only on mounted ram]
8. Turn off laptop
9. Repeat Step 2 and 3
10. Insert Ram removed in step 4
11. Turn on Laptop , it works fine
12. Turn Off Laptop
13. Put the back case back and screw them up

Conclusion

Congrats if you got your machine to work.

Just thought to share it ,as it was really frustrating thinking that I burned the motherboard, even while being so careful with the removal of LM as that is mostly the defaulter … If you got some queries you can get in touch over X @Hackology.

While I reduced PC GPU temps by 20 degrees, the impact on laptop wasn’t profound , although I am glad it’s still running and might wait a few days before reapplying as reseating the conductors over and again might ruin the PTM.
