In the event of a hard drive issue, it is time to start looking at our other tutorials or seek out a trusted professional. If you then see an error message, you’ll know that it’s a hard drive or drive connection/detection issue. The easiest way to verify this issue is to disconnect or remove the hard drive and power the laptop back on. It may give just a dark screen with a blinking cursor, start to load the desktop and only give a black background, or give a boot device error message. A bad hard drive or corrupted operating system can cause “black screen” by failing to load the operating system. If none of that solved the issue, then it is time to check the hard drive. If not you just identified a memory fault. If you get display after that it is possible the module(s) became unseated and needed to be reseated. You can verify this by powering down, swapping the original memory back in, and powering back on. If that gives you display, then you just found your issue. If the laptop powers on and you get a beep code power it back down and put new memory in. If you don’t see obvious physical damage from a fall, liquid spill or electrical damage then the most likely cause is a bad DC jack. It is usually determined by process of elimination of every other possibility. If it doesn’t, or it doesn’t power on, you may be looking at a bad board or bad power jack.Ī bad board can be harder to pin down. If it does, the motherboard is probably fine. The code itself doesn’t matter we just want to hear the motherboard complain about it. A functioning motherboard without RAM will give a beep code. Plug power back in and press the power button. Remove the covers, take the hard drive and RAM out, and set aside. Most of the time you’ll have panels on the bottom to access the memory and hard drive. Power down, if you haven’t yet and remove the battery. Motherboard, RAM and hard drive are the probable culprits here. If you see no indication of power and no hard drive status, it is time to look at the internals. You may need to review your laptop manual to ensure that you are enabling the external display correctly. If your external display works correctly, again refer to Cracked Screen. Try connecting another monitor or TV to the HDMI or VGA connection(s) on the side. Refer to Cracked Screen for more info on that subject. If it sounds like a normal startup and you hear beeps and boops or Windows startup sounds that is a good indicator that your black screen is actually a bad LCD. If something lights up and stays lit, it must be getting power. Check for any LEDs or keyboard backlighting to determine if power is being received to the circuitry. Black screens on a laptop can be an indicator that it isn’t even turning on or that the display isn’t getting power. Getting Power?įirst, verify you have power. Keep in mind, those can all be caused by age, wear and tear, surges, drops and spills. It could be caused by a bad LCD, motherboard, memory, power connection (dc jack), or even a hard drive. Causesīlack screen is typically an indicator of one of several possibilities. Some are easier than others and if you’re not feeling particularly brave they may leave you wanting a professional. There are several possible causes and I’m going to walk you through figuring them out. These are all referred to as Black Screen problems. You find yourself staring at a black screen, no logo, no loading screen, not even a blinking cursor (or maybe you DO only get a cursor)? A few moments later….you are still waiting. You open your laptop, hit the power button, and wait. Other solutionsĪside from disabling PSR, one solution also suggested turning off Frame Buffer Compression ( i915.enable_fbc=0) and mode setting ( i915.modset=0).Does this sound like you? You sit down at your desk ready to get that report done, watch a movie, or play a game. Price to pay to remove that screen flickering. Byĭisabling it, we lose that optimization at the cost of power efficiency-a Memory leaking from the frame buffer, causing us to see unsynced content. PSR addresses the latter by “remembering” a few frames into memory (the frameīuffer) so that refreshing takes less work. But it’s not that efficient whenĭisplay is static: reading from a website, idle time, etc. Like games, scrolling, or watching movies. It is good if you’re viewing dynamic content Most monitors have a 60 Hz refresh rate, so every second it updates what It’s directly tied to how a monitor displays contents to us. An optimization to reduce the power consumed by your computer, especially theĬhip.
