A Dell computer entering power saving mode usually means the monitor has lost its video signal, not that the monitor itself has failed. Wake the PC, confirm the monitor's selected input and cable connection, then restart the computer. If no Dell logo ever appears, treat it as a startup or hardware problem rather than a Windows power-setting problem.
Open your browser’s bookmarks or favorites list, select the saved link, and choose Delete or Remove. On a computer, you can usually right-click the bookmark; on a phone, open the browser menu, choose Bookmarks or Favorites, tap the item’s menu, and select Delete. Check the list again to confirm it disappeared.
Open Photos, tap Albums, scroll to Utilities, and tap Duplicates. Review each group, tap Merge, then confirm Merge [number] Items. iPhone keeps the best-quality version and moves the extra copies to Recently Deleted. This feature requires iOS 16 or later; if Duplicates is missing, leave the phone locked and connected to power while Photos finishes indexing.
On an iPhone running supported iOS 18.1 or later, open Settings > Apps > Phone, turn on Call Recording, and place or answer a call. After the other person answers, tap the Call Recording button. Both participants hear a recording notice, and the finished recording is saved in the Notes app. Availability varies by region and language.
On a Windows PC, press Windows + Shift + S to select part of the screen, then click the preview to save or edit it. For the whole screen, press Windows + PrtScn; Windows saves the image in Pictures > Screenshots. Pressing PrtScn alone copies the screen so you can paste it into Paint, Word, or an email.
To speed up a video on iPhone, open iMovie, create a movie project, add the video, tap the clip in the timeline, tap the speedometer button, drag the speed slider to the right, and preview it. Tap Done, then share or save the edited video as a new copy.
Open Settings, tap General, then About. Read the Model Name to see the iPhone you have, such as iPhone 13 or iPhone 15 Pro. For stronger confirmation, tap the value beside Model Number to switch from the part number to the A-number model identifier, then compare it with Apple’s official iPhone model list.
The YouTube audio renderer error usually means Windows and YouTube cannot share or reach the selected audio device. First restart the computer, then select the correct output in Settings > System > Sound, reconnect headphones or speakers, and restart the Windows Audio service. If the error remains, test another browser and update the audio driver.
If Windows says “incorrect PIN entered,” stop guessing and confirm that you are entering the Windows Hello PIN for the selected account, not the account password. Restart the PC once, then choose Sign-in options to try your password. If the PIN still fails, select “I forgot my PIN” and follow the account-verification steps. Do not continue after a lockout warning.
DISM Error 87 usually means the command syntax is incorrect, an option is misspelled, or the option is unsupported by that Windows installation. Open Windows Terminal or Command Prompt as administrator, enter the DISM command with spaces and forward slashes exactly as shown, then run CheckHealth, ScanHealth, and RestoreHealth in that order.
