HP Elitebook broken by a Hard Reset

[Marcos1985]

Hi,

My HP elitebook 2170p wasn't typing the keys G and H. So, I read somewhere that doing a hard reset sometimes restore the keyboard functionalities. I performed a hard reset (remove battery, power adpater and other acessories, pressed the power button for 30 seconds and connected the battery), but when I conected the battery the power button lits on and the charger light start blinking constantly each every second. I tried to turn on and nothing happens. No sound, no screen, no fan, nothing. When i remove the bettery and connected only the power AC the same happens. Surprisely, my USB charger port that i had previously desativated begin to work. So I drained the battery charging my phone and still doesn't work. I already performed another hard reset, removed the RAM memory and other components. With everything removed and connected to power cord the motherboard still blinks the charger light and power button lights on withou blinking. I don't know if this model turns on without battery. My question is: what the hard reset did to bronken my computer? Looks like that my computer now is unable to charge my battery!

Any idea of what i can do?

Thanks for attention!

A pretty old machine. I suspect it was having troubles already and the hard reset was its coup de gras.

I bought it a year ago. Do you that a new motherboard could be a solution or buy another one?

A new motherboard would be likely to fix it but unless you can do the labor yourself the cost will approach the price of a new laptop and with a new laptop you get current technology. This is a 3rd gen Intel Core processor and originally came with Windows 7 so it was manufactured like 5 years ago.
