Sys. Clock

[ncb1931]

I have a problem with my sys. clock keeping time. It will sometimes keep the right time but generally I will have to reset it via internet time. This problem has occured since I installed Windows 7 priemium.

I have a Dell Laptop XPS M1530

Check Cmos battery.

Is the time accurate at boot?

You may need to replace the computer's battery.

The computer battery is reading 100%. How do I check the CMOS? I am a newbie so make it as simple as possible.

The time is always off after a shutdown & then when I start back up.

I meant to just check the CMOS battery. If you are sure it is not the battery, you may want to read these posts.

Changing the battery will not be the issue here but accessing it may well be

If this laptop is still under warranty from Dell then they should do this change for you on request.

If it is out of warranty or the time that dell will take is an issue, and you feel up to the task you can do it yourself

Have a look here for instructions ....

Where is The CMOS battery located in the M1530 and how is it attached etc????

If you need to go at the battery attached to the motherboard of your laptop.
Download the manual from the Dell site for your machine.

Thanks for the advise folks. Thanks to Barman58 for the disassembly instructions. I believe it to be the cmos battery but being a one eyed shaky old 78 yr old young man will take it to a local geek. However I will keep u fellas advised on th final result.

In addition to the above, reset the time server to time-b.nist.gov. Using the Windows server that is the default caused the time to change irradically on my computer.

 

[ncb1931]

I have reset the clock to every time server listed in the USA to no avail===Thanks Anyway

How are you determing that the battery is 100%...by a monitor such as SpeedFan? If so, then you need to understand that the Vbat voltage is that of the circuit that powers the CMOS while the AC is running, not the battery itself. The only way that I know of to get the actual battery voltage is by manually checking it with a DVM.

If the battery is low, or your system just isn't keeping accurate time, this would be a workaround, but one that you might live with until you found a better solution:

I was going by the battery icon which I keep at the bottom of the taskbar --It reads 100%--U could be right-I still am thinking about going into the cmos bat myself but hate to screw up a $1500 laptop. Thanks

 

[ncb1931]

I am slow & old but it finally will come to me. I C what U mean about the battery. I was going by the icon which is telling me the bat is 100% "charged" nor 100% good aha The light finally clicked on. I can work around this clock thing just have to reset my clock several times a day.

 

[Barman58]

As I said in my earlier post the manufacturer should fix this fault for you if the system is in Warranty, In fact even if the machine is less than about 3-4 years old I would not expect the CMOS battery to be depleted. Of course there are cases of Bad batteries

My concern here is that there could be something else that is causing this with the state of the battery being a symptom and not the cause

the battery we talk about here isn't the battery that is powering on the laptop. This battery is like a watch's battery except that it is about 1cm diameter and is placed inside the computer. It keeps special information about the computer's hardware such as the time. This is why, when functionning correctly, when you close your computer for exemple for one month, when you power it on again, it will have the right time and date.

This is this battery that you need to change. However, I understand that with your age, you don't want to dissaemble your costly laptop. As many suggested, you may want to send it back to Dell if it's under warranty. If it isn't, go to your local computer shop and ask for it to be changed.

By the way, the battery looks like that :

I hope I was of help.

The computer was shipped from Dell on 6/18/2008. After these last posts I C where it could be several things other than the cmos bat. U guys R really technical. May C if Dell will do anything however I expect nothing other than the year warranty which I did not extend. Think I will set on it for awhile & think (dangerous for me). I can work around it but it bugs me.===Thanks Again
