HP ZE5185 Clock Problem

This laptop seems to work perfectly except for the time. It only keeps the time when the laptop is on. It wont update with the windows XP time server, I have to set it manually.
I have changed the CMOS battery with no luck. The old CMOS battery was a rechargeable Maxell ML1220 at 3 volts and it still had most of its charge.
Does someone know if I am using the correct voltage for the battery or is there something else I am missing?

Replacing the battery should do it. As long as you've got 2.7-3.3v coming from the battery you should be alright. These rechargeable can indeed run out of juice though and it's also possible that some part of the mechanism or firmware that works to keep it charged could be having problems.

None of that would explain why Windows' own time update fails though. What kind of error does it give when you attempt to update the time? Or does it update and shift out of whack immediately?

Hi. Try updating the BIOS first by downloading it from


The input jack to recharge my battery has bad connection

YES. This seems to be a common problem. I am just researching doing this with my Gateway.
Things to remember.
1) Shops which do this have the parts to do it right.
2) You might get a better price if you remove the motherboard and just send the mother board for soldering.
3) AND THIS IS VITAL. Some jacks are soldered in such that power is delivered to both sides of the motherboard using a copper sleeve. If you try this at home, you might not get the connection right.
Sorry for the bad news - talk to a shop which can do the repair. I saw prices of $90-$130 for everything except the shipping of course. . .
