Dell Inspiron 1570 Power on problems.

Hi All,
Hope there is a Dell expert out there as I am having issues getting this Dell Inspiron 1570 up and running.

The problem is when you attempt to power on you get a brief flash of the power light (blue) followed by 8 orange flashes. Doesn't attempt to power on no noises from fan just sits there flashing orange. According to most forums the problem is to do with charging or battery. I have so far replaced the battery with a genuine one and also changed the charger for a genuine one. Still getting the same issue. Just in case the power socket was faulty I changed that to, still giving the same symptoms. It has now become a damage limitation exercise and as a final resort ordered and replaced the system board but again no result, getting exactly the same flashing light sequence. I've tried disconnecting the connector to the screen in case that was causing the problem but still not attempting to power up any help would be appreciated.

At this point I'd try swapping memory, the HD and remove the optical drive.

You have covered just about everything there is.

If the above doesn't work it might be time for a new laptop.

Thank you for your answer Scottcha, Have also tried the memory trying a stick at a time in each slot alternatively plus removing keyboard hard drive and optical drive would be nice if I could lay my hands on a proper service manual with the error codes on. Only thing left is the screen and cable. strange thing it was working prior to being left on shelf. I have also tried disconnecting battery and power cord holding down power button for 10 seconds re-inserting battery and power cord, switched on , same sequence of flashing lights. Maybe I have been sent a faulty motherboard. I have now left the charger in place and will try in the morning in case battery is very low.

Don't know if there are flashing codes in it though.

My original diagnosis was the motherboard. Having received the board and fitted it I was still getting the same symptoms so logically I considered it may be something else like memory battery or screen cable all to no avail I had ordered a second board just in case which I fitted today and it resolved the issue. There are times when you begin to doubt your own logic.
