Hello everyone.
This is my development machine. I've been using it since two years and half without any problem except sometimes it wouldn't wake up from sleep.
Lately the issue became more frequent and powering it up would take few seconds to show the POST screen.
Then the computer refuses to power on at all. Now only the caps lock button flashes 7 times then stops. The charging light is always on whenever a power source is connected (battery or charger).
I tried long pressing on the power button, after several seconds it would go off then when the button is released... -

Working on a hp x360 15-eb1043dx that will not turn on and the power light just flashes. It pulls 700ma when flashing. Under the thermocam I found a component I am unable to id that light up. If someone can help would be appreciated. I put the number that are on it in better test....

un65tu7000fxza - I am experiencing the flashing red light on the power led. So I purchased the replacement kit for the mainboard and power supply. I still experienced the flash red power light. So I purchased a new ribbon cable, The flashing light stopped for a minute, I could hear sounds on the TV but no picture. I did the 60 second reset and it went back to flashing. What could possibly be the issue now? All the LEDs are lit up from what I can see.
Thanks for all responses. -
