> I have a Dell Lattitude e7450 laptop that ran out of battery while I was watching a show. I tried to follow a solution from a subreddit that involved removing the battery and holding the power button, but it did not work. The laptop has been plugged in for an hour, but it still does not show any signs of life. The only thing that happens is that the leftmost LED on the back flashes briefly when I press the power button. This is not the first time this has happened, but I do not know what caused it or how it was resolved before.

How to troubleshoot a Dell Lattitude e7450 laptop that does not power on after running out of battery

If you have a Dell Lattitude e7450 laptop that does not turn on after running out of battery, you may be facing a common issue that affects many laptops of this model. This issue is caused by a faulty power management system that prevents the laptop from charging or booting up properly. Fortunately, there are some steps you can take to try to fix this problem and restore your laptop to normal operation.

The first thing you should do is to reset the BIOS (Basic Input/Output System) of your laptop. The BIOS is a program that controls the basic functions of your laptop, such as booting up, detecting hardware, and managing power. Sometimes, the BIOS settings can get corrupted or misconfigured, which can cause your laptop to not power on or charge correctly. To reset the BIOS, you need to follow these steps:

• Unplug the AC adapter from your laptop and remove the battery.
• Press and hold the power button for 15 seconds. This will drain any residual power from the laptop and clear the BIOS memory.
• Reinsert the battery and plug in the AC adapter.
• Press the power button to turn on your laptop. You should see a message that says “BIOS defaults loaded” or something similar. This means that the BIOS has been reset to its default settings.
• Press the F2 key repeatedly to enter the BIOS setup menu. You can also press the F12 key to access the boot menu and select “BIOS setup”.
• In the BIOS setup menu, go to the “Exit” tab and select “Save Changes and Exit”. This will save the new BIOS settings and restart your laptop.

If your laptop powers on normally after resetting the BIOS, then you have successfully fixed the issue. If not, you can try the next step.

Step 2: Update the BIOS

If resetting the BIOS does not work, you may need to update the BIOS to the latest version. Updating the BIOS can fix some bugs and improve the performance and compatibility of your laptop. However, updating the BIOS is a risky process that can potentially damage your laptop if done incorrectly. Therefore, you should only update the BIOS if you are confident and experienced in doing so. To update the BIOS, you need to follow these steps:

• Go to the Dell support website and enter your laptop’s service tag or model number. You can find the service tag on a sticker on the bottom of your laptop or in the BIOS setup menu.
• On the support page, go to the “Drivers and Downloads” section and select “BIOS” from the category list. You should see the latest BIOS version available for your laptop. Check the release date and the version number to make sure it is newer than the one you have currently installed. You can check your current BIOS version in the BIOS setup menu or by typing “msinfo32” in the Windows search box and looking for the “BIOS Version/Date” field.
• Download the BIOS update file and save it to a USB flash drive or an external hard drive. Do not save it to your laptop’s internal hard drive, as you will need to access it from outside Windows.
• Plug the USB flash drive or the external hard drive into your laptop and restart your laptop. Press the F12 key repeatedly to access the boot menu and select the USB or external device as the boot option. You should see a message that says “Press any key to boot from CD or DVD” or something similar. Press any key to continue.
• You should see a screen that says “Dell BIOS Flash Utility” or something similar. Follow the on-screen instructions to update the BIOS. Do not turn off your laptop or interrupt the process until it is completed. This may take several minutes.
• After the BIOS update is done, your laptop will restart automatically. You should see a message that says “BIOS update successful” or something similar. This means that the BIOS has been updated to the latest version.

If your laptop powers on normally after updating the BIOS, then you have successfully fixed the issue. If not, you can try the next step.

Step 3: Contact Dell support

If none of the above steps work, you may have a hardware problem that requires professional assistance. You should contact Dell support and explain your situation. They may be able to offer you some troubleshooting tips or arrange for a repair or replacement of your laptop. You can contact Dell support by phone, email, chat, or social media. You can find the contact information on the Dell support website or in the user manual of your laptop.
