Envy 14 - Date and time is always wrong. Time to replace CMOS battery?

Hi guys,

I've had my Envy 14 for roughly 1.5 years now and all of a sudden I always get incorrect time/date no matter if it's manually put it or synced. After doing some research it seems like the CMOS battery may need replacing (Although I thought that are meant to last 4+ yrs :/).

I'm a bit of a novice when it comes to fixing computer hardware so I have just a few questions if anyone can help me -

1. When I open up my laptop the circular object wrapped in yellow plastic I'm guessing is the CMOS battery?
2. If it is, I've noticed my CMOS battery is not glued on to the motherboard. If someone can open up their envy can confirm if theirs is psychically stuck to the motherboard or just connected by wires and floating about?
3. Does the Envy 14 have a specific CMOS battery type, and/or where could I get one?
4. If anyone has replaced their CMOS battery, is it pretty straight forward?

I'm a bit worried as I've never tinkered with computer hardware before. If anyone has any suggestions that may fix the time problem before I attempt to replace the CMOS battery that would be great.

 

That's no ordinary battery, per se. You have to get it from HP or a third party vendor.

Part #: 581926-001

You can find it in HP's part store, eBay, or Google that part number and a list of vendors will come up.

It shouldn't be floating about. Likely you don't need a new one but need to glue or tape it down and make sure its connector is firmly in the socket.

See page 51 of the service manual: http://h10032.www1.hp.com/ctg/Manual/c02835360.pdf

 

Mine isnt stuck to the MoBo either (lost stickiness), but I dont have issues otherwise.

 

Hm mine has also lost stickiness. What I am wondering is whether or not the CMOS battery has to be/is meant to be stuck to the motherboard. Is there some sort of connectivity through the battery when attached to the motherboard?

Seems like this battery is not easy to come by. Hopefully I can find a fix without having to replace it :/

 

No, there's no connectivity through the battery. Though with it flopping around, its connector could come lose. Which is probably what has happened to yours.

As stated before, make sure its connector is firmly in the socket and then tape of glue the battery to the motherboard.

These batteries are designed to last 5 years or more.

 

I need help too. I have an Envy 14 with 1600x900 Radiance Panel a 120gb SSD and I added the slice battery. My time was off as well and I bought the new battery from HP and installed it, guess what? It still is off, it only goes off when the computer is shut down.

I tried.
1. Removing the slice battery and seeing
2. Changing to a different primary battery, I have two
3. Opening it again and attaching the battery with black electrical tape.

Do you think it has to be firmly attached to the motherboard to work? It looks like the previous owner had a few black strips of tape holding his in place, would love some advice.

It was a surprise to see my thread resurrected . I do check these forums once in a while as my Envy is still going strong.

All I did to solve the problem was making sure the wire connecting the CMOS battery was clicked in with a 'click' sound to the motherboard. I believe mine wasn't connected properly which would explain the time/date inaccuracies. No tape is needed to tape it down, just make sure is connected properly. Hope this helps.

 

Hey, just to reassure people, the same thing happened to my Envy 14 - I opened, found the CMOS battery and it was taped and well connected, so I thought "damn it" - Nonetheless, I went ahead and disconnected it and plugged it in again and that fixed the problem! It's been around 2 months now and everything is perfect.
