Hi there, Thank you for sharing your review with us. We're sorry to hear that your Philips Norelco OneBlade 360 is not turning on. We recommend trying the following suggestions to resolve this issue. For safety reasons, the Philips OneBlade only operates cordlessly. Please ensure that your OneBlade is not plugged into an electrical socket. If it is, please unplug it and then try turning it on again. It's possible your OneBlade isn't charged properly. Switch it off, then insert the charging cable at the bottom and plug it into a 120V AC outlet using the original Philips adaptor. Check the blade for clogs or wear. If it's clogged, rinse or soak it in lukewarm water. Don't tap it on a hard surface. Replace damaged blades. Buy new blades in our online shop. Some OneBlade models feature a 'travel lock' that can be deactivated by pressing the on/off button for 3 seconds. If your OneBlade model features a digital display, a padlock symbol will be displayed when the travel lock is activated. If the issue persists, please get in touch via Social Media. We’re available on Facebook (@Philips) and X(@PhilipsCare). Don’t worry, if you don’t use Social Media, you can also reach out to us via the contact page: www.Philips.com/contact. Hope to speak to you soon! Best regards, Philips Consumer Care
