HP Elitebook 2570p not starting

[dan_7382489536]

My Elitebook 2570p is refusing to start, any help would be MASSIVELY appreciated! Thank you. [Linux Mint 19.1]

I had the laptop running and I shut down (or at least I think I did) before taking out the six cell battery - I did this because with that battery in the laptop is too big to fit into my little neoprene pouch, so I was intending to put the 3 cell battery in.

When I put the 3 cell battery in I noticed that some of the LED indicators were on, when it should have all been switched off. I suspect, although I don't know for sure, that the laptop may have been restarting when I whipped the 6 cell battery out.

Now the laptop will not start. I've tried a hard reset (power button down for a minute or so with PSU and battery out). No change.

Indicators as follows:

1. Power supply connected
2. The battery (lightning symbol) LED comes on immediately (orange)
3. After ~ 1 second the power LED comes on white, and the battery LED begins to flash white/orange * continuously.

* The battery LED flashes white/orange cycling every 0.75 seconds (timed), white and orange phases look about the same length.

NOTE: This sequence above is the same whether I apply the power from the PSU, OR from either battery.

There's no sound that I can hear although there's only an SSD in there, and the laptop will not start or do anything else beyond this point.

Also, cannot get it to start from a bootable USB , don't think it's getting anywhere near booting tbh.

Does the LED pattern above indicate anything specific?

Many thanks for reading.

I wish we could help you from here, but we can't. The problem is that we HERE, have no way of diagnosing or repairing hardware problems. And, with the PC not even starting, even HP Tech Support, who have the authority and tools to REMOTE into a PC across the Internet, can not access your PC.

Software failures invariably present with error messages of some kind on the screen, such as No Operating System or No Boot Device. In these cases, reinstalling the OS from media such as DVD or USB fixes the first; rebuilding the boot records using various utilities fixes the second. But any time a laptop simply refuses to turn on, that tend to indicate a serious hardware failure.

If your PC is still under the original one-year HP warranty, or if you have purchased an extended warranty from HP and this is still valid, then you should contact HP Customer Support to see about having it repaired or replaced under warranty.

If you live in the US or Canada, contact information is on this page: http://www8.hp.com/us/en/contact-hp/phone-assist.html#section1

If you live elsewhere, contact information is on this page: http://www8.hp.com/us/en/contact-hp/ww-contact-us.html

NOTE: After you get through, stay on the line until you are finally able to talk to some one -- it can take a while!
If you have trouble finding a phone number, then try: 1 (800) 474-6836

If your PC is no longer under warranty, you will have to contact an HP Repair or Service Center to see if they can examine the PC to determine the cause(s) of the problems, if it can be repaired, and an estimate of the repair costs.

If you live in the U.S., here is a link to the HP Service Repair Centers:

If you live outside the U.S., here is a link to HP Service Centers, by Country/Region: https://support.hp.com/in-en/service-center

Good Luck

Sorry for asking; I just rather thought the clear description of LED flash sequences on startup might indicate to someone on an HP forum, which item(s) of hardware I ought to be looking at as a culprit. Apologies if I've wasted your time.
