I have the similar problem. I will try to remove the HDD and RAM, then will do a reset. I hope this works. Thanks.

tried took off the hard drive and memory, did the hard reset, put all back again. turned on, still blinking. 😞

Yah, it still blinks, but you'll notice it turns off after a number of blinks. (mine turns off after 4 blinks, meaning the graphics is not functioning properly, probably needs to be resoldered). After a hard reset, use the power adapter, not the battery.

Sandpaper on memory modules????   Not a good idea

HP Recommended

I said lightly rub and clean it will engage to connect the system

HP Recommended

With Sandpaper....a bad idea

try a hard reset instead: ( it is much safer)

Remove the battery and unplug the DC power adapter.
press and hold the power button for more than fifteen seconds.
plug in the DC power adapter (leave the battery out for now)
press the power button
