Update all firmware on HP DL380 G5 server

The simplest answer is, in this case, the correct answer: You will no longer be able to get firmware updates for HP equipment which is not (a) under its original factory warranty, or (b) covered by an active support contract with HP.

This has a number of implications, chief among them:

• As a sysadmin you will have to ensure that you have an HP support contract to get continued firmware upgrades for machines that are beyond the factory warranty period.

• As a business this alters the cost of continuing to operate equipment beyond its initial factory warranty period (as you now have to purchase support contracts, which adds to the cost of the equipment).

Ultimately what this means is the cost/benefit analysis of running HP hardware has just become more complex. How that analysis plays out for you, your company, or your clients will depends on your own internal requirements, constraints, and budgeting (and likely on your company's relationship with HP -- A company buying $500,000 of HP gear every quarter will likely get more favorable support contract terms than one that buys $50,000 every 5 years).

I think you purchased a bad battery.

You could try a full power off of the system (removing power cables) and try again. But you've most likely acquired a bad battery.
