Problem after replacing RTC battery on COMPAQ Presario 6000

I replaced the CR2032 battery on the motherboard, without difficulty. I should have downloaded the instructions on doing this from the excellent HP/COMPAQ website. What I should have done next was press the START button BEFORE switching on mains power. When mains power is switched on, the computer switches itself on, but does not BOOT-up. The VDU is blank and the HDD activity LED is unlit. How do I recover the system.

Check your work.

A dead battery could do that. So check you got it in right side up and if that fails put the old battery in.

RTC battery Change

Thanks Bob. Already done what you suggested. No luck. Thanks.

Tell a little more.

Did it work prior to this?

Does that CMOS RESET do anything?

Are you sure that we didn't bend the little battery contact too much and lose contact with the battery?

RTC battery replacement problem

Thanks, Bob. Prior to the battery replacement the computer worked perfectly. As the battery had expired, the system required me to reset the date and time, manually. After this, operation was normal.

I can't use this reply to answer my questions. Hopefully the clue is in my questions.

Beyond that, it is possible some card or cable was dislodged. When I write "check your work" I meant but didn't write you need to give all the cards and cables a gentle push home.
