Notebook Boot and Lockup

After I install a new SDD (also after removing) on the Probook 430 G2 from my wife - now is not working any more. 

I only get a 7 times white blinking together on the LED that is in the caps look and in the scroll (num lk) keys. 

If I am not wrong this is not on the table here: https://support.hp.com/sk-en/document/c01732674.

According this post https://h30434.www3.hp.com/t5/Notebook-Boot-and-Lockup/Caps-lock-and-num-lock-blink-for-7-times/td-p... (the only result for 7 times caps look blinking on HP laptops on Google), it should be a BIOS or CMOS error: I tried pressing Windows+B and Windows+V with the original HDD and with a USB Stick with the last BIOS, and I removed the CMOS Battery. Nothing helps. 

It seams the new SSD is broken and has broken the HP laptop: 

I tested the SSD (only with a shot look with gpared - like Disk Management in Windows) with my external HDD to USB adapter: is seams the SSD are working, but I was shocked as I want to save the data on the HDD from the laptop, I seams the HDD is broken. I check the HDD in two other computers: the HDD is working (I saved the data). - An incompatibility between the HDD and the USB adapter? - No, I checked another HDD that was working before on the USB adapter: same issue: the HDD is not working with the USB adapter any more. - It seams the new SSD has broken the HP laptop and the USB adapter. - But the curious thing is that the SSD is still working on the USB adapter. I am confused.
