# Lambda Laptop keeps losing timezone

## post by jamualford on Oct 17, 2021
Every second or third time I turn on my Lambda laptop it is on the wrong time zone and I need to reset it. Is this a CMOS battery issue and if so are there instructions to change it?

Hi Jamaul,

How are you resetting the timezone? Assuming you’re using a systemd OS, you can change the timezone with the `timedatectl` command. You’ll have to find your specific timezone first. For example, I’m CST which equates to America/Chicago, which can be found by the following:

> timedatectl list-timezones \| grep Chicago  
> America/Chicago

Then, to set the timezone:

> timedatectl set-timezone America/Chicago

If this doesn’t work, I’m not sure if a CMOS reset will work but here is how:
1. Unplug the machine from the charging cable
2. Follow this [guide](https://files.lambdalabs.com/guides/Gen4-Tensorbook/Motherboard/index.html) to remove the bottom tray
3. Remove the battery.
4. Press the power button for 10-15 seconds.
5. Reinstall the battery.
6. Place the bottom tray back on with the screws.
7. Plug in the charging cable and boot again.

Hopefully this helps and should you require more assistance with this, I’d highly recommend opening a ticket with us by emailing [support@lambdal.com](mailto:support@lambdal.com)
