Why is short DST not available on my HP laptop?

Daylight Saving Time (DST) is the practice of setting clocks forward by one hour during the summer months and back again in the fall. The goal of DST is to make better use of daylight hours. Most smartphones, computers, and other devices automatically adjust for DST changes. However, sometimes DST settings can get out of sync, leading to issues like short DST not being available.

There are a few potential reasons why short DST may not be showing up as an option on your HP laptop:

Incorrect DST Settings

The most common reason is that the DST settings are incorrectly configured. Go to the Date and Time settings on your laptop and double check that “Adjust for daylight saving time automatically” is enabled. If it’s disabled, enable it and choose your time zone. This will sync your clock to use the correct DST rules.

You can also manually set DST start and end dates. Make sure they match the DST schedule for your time zone in 2023. DST in the US starts on March 12, 2023 and ends on November 5, 2023 this year.

After updating DST settings, restart your laptop and check if short DST now shows as an option.

Outdated Operating System

Your OS version may be outdated and missing the latest DST rules. HP releases periodic OS updates that include DST calendar changes.

Go to Windows Update and install all pending updates. Reboot your laptop and see if that fixes the issue. You can also manually update to the latest OS version available for your model.

For older laptops, updating the OS may not be possible. In that case, you’ll have to manually change DST dates as a workaround.

BIOS Clock Issue

Rarely, the hardware clock in the BIOS may be set incorrectly. This can prevent OS DST adjustments from working properly.

To rule this out, check the date/time in BIOS and make sure it’s accurate. If not, change the settings to sync with an online time server and your local time zone.

You’ll typically need to press F10 or DEL during boot to access the BIOS. Change the settings, save changes and exit. Boot back into Windows and check for short DST.

Troubleshooting Steps

Here are the key troubleshooting steps to resolve short DST missing on an HP laptop:

1 Go to Date and Time settings in Windows
2 Enable “Set time zone automatically” and “Adjust for DST automatically”
3 Manually set DST start and end dates for your region
4 Restart laptop and check for short DST option
5 Update Windows OS to latest available version
6 Reboot and check for short DST after update
7 If issue persists, enter BIOS and confirm date/time is correct
8 Make changes if needed and save BIOS settings
9 Start laptop into Windows and test for short DST again

Following these steps will synchronize your system’s DST settings and resolve any mismatches. Short DST should then become available as an option.

Why HP Laptops Specifically?

There are a few reasons why HP laptops are more prone to having DST issues like missing short DST options:

HP’s Approach to BIOS/UEFI Firmware

HP laptops utilize proprietary HP firmware for the BIOS and UEFI instead of leveraging the industry standard coreboot BIOS. This increases the likelihood of low-level date/time bugs. If the hardware clock in UEFI gets out of sync, it can prevent correct DST adjustment in the OS.

Slower OS Updates

HP can be slower than other OEMs in testing and rolling out the latest Windows updates. This may result in outdated DST rules on older laptops. Automated DST adjustments rely on up-to-date OS builds.

Region Specific Issues

DST rules vary across regions. HP may not thoroughly test DST implementations across all global time zones. So laptops shipped to certain regions can exhibit issues like missing short DST.

Daylight Saving Time Complexity

In general, DST rules have become more complex over time. OEMs struggle to keep up with frequent DST rule changes across global markets. This can manifest as DST bugs on specific models and regions.

So in summary, HP’s firmware design, slower update release cadence, uneven global testing, and the intricacy of DST rules contribute to a higher rate of DST date discrepancies on their laptops.

How to Prevent Short DST Issues

You can take the following steps to avoid short DST not showing up on your HP laptop in the future:

Manually Update OS

Rather than wait for HP to push OS updates, manually install the latest Windows version yourself. This gives you access to DST fixes as soon as Microsoft releases them.

Change Update Settings

Enable automatic Windows updates so you always have the most recent DST rules. Reboot as soon as updates are available.

Use DST Registry Tweaks

There are some registry modifications that force Windows to use the United States’ DST calendar regardless of your time zone. This can act as a temporary workaround if localized DST is broken.

Confirm Time Zone

Double check your configured Windows time zone matches your physical location. Incorrect zones can lead to mismatch between expected and actual DST.

Use Desktop DST App

Consider a third-party DST app to override system settings. These apps sit in the tray and automatically adjust clocks based on custom calendars.


In summary, short DST not appearing on HP laptops is typically caused by incorrect DST configuration in Windows or the BIOS firmware. Following the troubleshooting steps outlined can help resolve configuration issues and enable short DST. Slow OS updates from HP contribute to a higher rate of DST bugs on their laptops. Manually updating Windows, using DST tweaks, and confirming your time zone can help prevent short DST problems in the future. With the right fixes, you can get short DST working properly on your HP laptop.
