I have an inspiron1545 and the other day I got time of day clock stopped message. I replaced the coin cell battery inside but now it won't turn on. I get no lights with charger in. it's just dead. Please help.

Not relevant to members in other countries around the world but have you checked the fuse (sorry but got to ask).
Have you tried removing the battery and running with only the AC adapter connected and likewise battery only and no AC adapter connected, is there a power light on the AC adapter and if so is it illuminated when powered on and finally is the laptops power jack secure when connected.

Tried all combinations power wise. The AC adaptor is illuminated. I don't think the battery was charging beforehand because the power light was flashing. It's just totally dead now since replacing the battery inside.

Try removing the battery and the Ram then holding down the power button for around 30 seconds, this will dispel any static charge that can sometimes build up and prevent booting, once done reassemble but leave the battery out then try booting up.
It is possible that your AC adapter is faulty, did you check the laptops power jack, these can become loose and cause a short which will also prevent booting.

I have 19.6v on the back of the power jack with the adaptor in so this doesn't seem to be the problem. Any more suggestions?

At this time I can only think of a short in the MB, go back over the reassembly process when you changed the RTC battery, any stray or missing screws etc?

[Craig Malkin]

Problem solved. Thanks for your help. A missing screw from the mobo. My battery still won't charge but minor problem

Good news and thank you for posting the solution as it may help others in the future with the same or a similar issue.
This is the very reason why laptops are expensive to repair, they can be so tricky,
