Laptop won't boot after onboard battery is changed.

Hi there.

I have an oooooooooooold HP ZT3020 laptop. Amazingly it was working untill two days ago... beside that the battery has been dead for a long time. But now the onboard battery died too, because I had to set the date/time every time I boot it.
I bought a new onboard battery (CR 1220) and expected the computer to boot as always.... but as you probably figured out, nope! No harddisk-indicator, dead screen.... only the Wi-Fi indicator is on, and the DVD-drive scrambled a little... and the fan is running too. No error-beep from the BIOS or so.
What can be wrong? It worked for 8 years now... yeah yeah... I know I'm demanding, but changing the onboard battery should kill it??? Beside damaging the BIOS maybe? So I wondered if anyone knows how to kinda hard-reset the BIOS? Taking out the battery usually does the job, but onviously not in this case.
I'm looking forward to some nostalgic responses. :o)

Best regards

A dead or disconnected CMOS battery will reset BIOS settings. Can you boot the laptop to the BIOS screen? Power on and keep htting F2 or F8 (i think thats HP) when you see the HP logo.

If you get to BIOS, check to see that your harddrive is recognized and that it is in the Boot list.

BTW, I have had a dead laptop battery for years now myself. I know.

Hi again.

Computers are wonderful... because sometimes the problem is solved after messing around with it... :o)  I took out RAM, harddisk and CMOS battery once more... put it all back... except the laptopbattery. Bingo! Here it looked all normal again... I also stuffed the battery back in, and it still worked and could reboot.
I think the ooooooooooooold BIOS got totally scared to get a brand new CMOS battery again, that it got messed up. Amazing, huh?  It's all working again.
And Mez4343... no, there was no BIOS-screen or anything... but who cares? Now it's back on track. Thanks for your time. Easy points. ;-)

Best regards

well thats good. so if you cant even get the BIOS screen to show after hitting F2 then that would point to a hardware device not plugged in all the way. so what you did with reseating the memory and battery fixed it. 1 more year!

I thought HPs use F1 or F10 for BIOS setup; Dell uses F2.
