Re: HP Probook 450 G6

If do you mean 3 long - 2 short ok. If you see 2 long - 3 short is related to a firmware error in the ec, and not to Ram.

With ram inserted which blink sequence?

Re: HP Probook 450 G6

Have you checked if there is signs of oxidation/water damage?

The current draw test suggested by mcplslg123 would also be important if you can do it

Check also this...

Uploaded small movie of blinking. Without ram.

You dont have a dc supply?? If yes, then measure SDA/SCL/DRAMRST# on ram slot. It's very important to see activity on SDA/SCL lines and that can be observed only on DSO. If you dont have these tools, i'll suggest to get in touch with a professional nearby who has the necessary skills and tools.
