Hi, I client has this notebook and once I turn it on, I get a short white LED capslock blink. Power adapter is fine, I get a reading for 19V. I see also a white LED on the side of the notebook - on the power input jack and lower near the end. When battery removed, I also get the same LED blink status.

I did a CMOS and RAM refresh, still same trouble. Also, the PIN pads for the input were a little corroded, I wasn't getting any reading on the pads, so I cleaned them up  and now I'm getting a voltage reading but still same issue. I hear no HDD spin. Could it be the CPU is dead?

I get the diagnostic tool to check disk and memory and those tests passed.
