Hi
I have repaired an Inspiron 15 5547 with the known hinge issue. It also required a new WiFi Antennta, due to the cables being damaged. After replacing the top palm rest the laptop will no longer boot. Following a user guide most of the laptop parts had to be removed. the laptop was fully working prior to the work.
Fault:
Upon pressing the power button the fan starts to turn. after a few seconds the laptop powers down. No display is shown on the screen and no beeps. The white power light flashes once.
If you connect the power cable in the white power LED flashes once
If the laptop is left by itself after a fail boot the fan starts up and spins highly.
Diagnostics:
To check the laptop is performing POST I have disconnecting the LCD screen and then removed the RAM.
I heard 8 beeps - for LCD
On the RAM removal i heard 2 beeps.
All connectors are in place.
On one test boot the hard drive white illuminated for a split second and it looked like the laptop was going to boot, however it powered off.
I have held the power button down for 30 seconds, without the battery and power cable in.
Has anyone had this issue before?
Am i looking at a motherboard failure?
I doesn't show any fault lights apart from a single flash of the power white LED light.
Thank you.
