Acer Predator PT516-51s Performance Results - UserBenchmark. Ajrv31 Member Posts: 6 New User. Unfortunately Acer does not ship Aspire 7 in different colors, so microfiber cloth is the #1 accessory you should buy for your laptop. What accessory you shouldn't buy for this laptop is a dongle. Aspire 7 has almost all necessary ports: 2×USB-A's, Thunderbolt 4 Type-C, HDMI, and Gigabit Ethernet on the left; with one more USB-A, 3.5 mm Hello I just purchased new Acer Nitro 5 AN515-55. It has 2 USB port on the left side and 1 port on the right. After finished setting up the laptop, I tested every single USB port with my wired mouse and keyboard. To my surprise, only the USB port on the right side able to turn on and detect my devices. Meanwhile both USB port on the left side Itis like a + and - sign symbol as though somebody is trying to shift the battery out. Insert the pin on to the hole for 30 seconds. Remove the pin. Flip the laptop. Connect the charger cable, turn on the computer. Only on laptops where the battery is inbuilt you can find the battery reset hole on the back of laptop. cnMember Posts: 1. May 2013. I have an aspire 5733 and the 2 usb ports on the right side wont work.Ive tried flash drives, printer, and nouse on both but nothing is registering on them. Only the 1 on the left is working. Device manager says everything is working properly and ive disabled and enabled and done pretty much anything i can think of. Atfirst check it again with other USB device like pen drive. if it not work, I think your USB driver may damaged. So you may find it through internet. 1. First search the USB driver software (must write your laptop model) 2. Download the mention driver software Then uninstall your previous USB driver. 3. Now install downloaded driver correctly.
