Possible heat damaged i5-2520 in an HP Elitebook 8460P

[Tug00]

I let an HP Elitebook 8460P basically run non-stop as a desktop for about a year & a half. Sometimes I used it as a rendering machine so I know that makes the CPU and GPU get hot although I never got a single shutoff of the computer by the CPU or motherboard because of excessive heat. It has an Intel i5-2520 CPU and uses the integrated GPU with no discrete GPU at all.

Recently I bought a used HP Elitebook 8470P and I turned off the HP 8460P for a few days. Now when I turn it on the fan, indicator lights, and DVD run for about 4 seconds with no video and the computer cuts back off. It isn't a battery or power supply problem. I think that when the computer cooled completely down a solder somewhere broke and now the computer doesn't work, but I'm not sure that is what has happened.

The computer is otherwise in good shape. What can I do to fix it outside of this 'reflow' solution I read of? Will replacing the CPU likely fix it? I think an old i5-2520 probably could be bought cheap on eBay but I don't want to waste money on it if that's not going to fix it.

I guess I will start scheduling overnight shutdowns for my replacement HP 8470P laptop to avoid the same problem recurring.

Thanks

I haven't replaced the thermal grease or compressed air cleaned it no, but I have done the other things already.

I will reapply thermal paste when I upgrade the i5 CPU with 2 cores in my HP 8470P to an i7 with 4 cores as I don't want to waste the thermal grease as at $3.29 and a hassle to order and wait I don't want to use it all or have it dry out as it's not a very big syringe.  If that doesn't work I will buy a used CPU on eBay. Means I need to get 3 doses of thermal grease out of that syringe. 

I clean installed Windows 10 on a 100 GB used HD  before I turned it off for a week so I'm pretty sure your suggestions or a replacement CPU will work.

Thanks.

I have around 100 of the HP 8470P in the warehouse.

If you need any help with it let me know.

Wow, OK. I may need help if I goof up when I switch out the CPUs. I don't intend to do as near as heavy rendering nearly so often with it and I've already configured it to go to sleep after a while of non-use to try and avoid what happen to the HP 8460P.

Thanks very much.

If you live in the  US  I could have offered a unit for free. "You pay shipping"

I have thousands of laptops to pick from.

If we can help in the future let me know.

REO

[Tug00]

I do live in the US. I'll be glad to pay shipping to have a laptop I can use just for rendering while I use the one I just bought for everything else.

Should I PM you in this forum? I live in Kentucky actually.

PM me and lets see what we can do.

Would you need HDD, AC???

Windows 10 and COA would be extra.

Click on Laptops and Hybrids then HP EliteBook Notebook PC's.

Then scroll down to HP EliteBook 8560w Mobile Workstation.

This is the type I was looking for.

Work Stations, most of the time will have 4 memory slots.

4x4=16GB   and some   4x8=32GB

I tested a few that had M.2 SSD slots also.

Some worked but they had dings, rub marks, bad displays just not what i wanted.

Then around noon the warehouse manager informed me that everything had been tested.

We have our first shipping container going out next Tuesday since Hurricane Irma hit us.

I think a Mobil WorkStation is best.
