#LENOVO CRITICAL UPDATES STUCK BIOS MANUAL#

There are web pages with information on these beep codes, but your best bet is to look at the manual for your specific PC or motherboard, as it’ll be most accurate. (Other machines may have a digital display that shows error codes instead of beeps, or a series of lights that turn on in a specific order to indicate a problem.) It could be a failing stick of RAM, a CPU that’s overheating, or a video card that isn’t seated properly.

But if it makes a specific sequence of beeps-say, one long beep, then two short beeps-it’s trying to tell you something. If your PC just makes a quick beeping noise when it boots, then it isn’t registering any hardware problems. If you don’t have one, you can order one on Amazon (Opens in a new window) and plug it into the speaker header on your motherboard. This speaker exists to give you error codes when something goes wrong. When your desktop PC boots up, you’ll usually hear a small beep from a speaker that lives inside the tower. HDMI-to-VGA adapters (Opens in a new window), for example, only work in that direction-if you're trying to hook a VGA computer to a DVI monitor, you'll need a different type of active converter (Opens in a new window). If you're using adapters, those could be the culprit as well-either you have a faulty dongle, or you're using it in a way it wasn't intended to be used.

Remember, not all cables are created equal: if you're trying to run a 4K display at a high refresh rate, you'll need an Ultra High Speed HDMI cable, rather than an older High Speed model. If you're using DisplayPort, make sure it's certified by VESA (Opens in a new window) for HDMI, it may have a certification label on the packaging you can scan with the HDMI Cable Certification app for iPhone (Opens in a new window) or Android (Opens in a new window). In addition, make sure your cable has the right specs for the job. You might also try a different cable type-say, an HDMI cable instead of a DisplayPort cable-to see if that solves the issue. If you have any extra cables lying around, try another one-maybe the cable you’ve been using is damaged, or one of the ports is malfunctioning. If you have a graphics card, your monitor should be plugged into that, not the HDMI port on your motherboard.
