DV7 - Power switch, logo and power & disk LEDs flashing

[britesc]

Hi,

First off I am very partially sighted and have worked on this project for some months. So please be kind to me. 🙏

I have replaced the motherboard, CPU and fan, also Bluetooth module, on my laptop. It is at last back together but when I attempt to power it on, I get the following response.

1. The Power Switch.

2. The Power LED.

3. The Orange Disk Activity LED.

4. The front cover powered HP Logo.

All flash at a steady 5 seconds Off 1second On.

Nothing else responds, no display or drive or fan noise.

This only happens when the laptop is on external power from the adaptor unit. (The LED next to the power socket is illuminated).

If unplugged, nothing happens whilst just on battery.

(I am assuming the battery is not charging).

Could anyone please advise me on what I now need to do. I have trawled the web, with difficulty, but am unable to fathom this out. I cannot afford major financial outgoings.

Thanking you in advance.
