So you turn on your laptop and it powers on, but the screen does nothing. Your first instinct might tell you that the computer is broken. Don’t go throwing it agains the wall or out the window just yet, you may want to try one of these tricks first to save some of your hard earned money from buying a new one. Sometimes computers get stuck in sleep mode and it ends up resulting in your screen doing nothing when you turn your computer on. Hopefully this is the case for you because there are a couple things you can do to easily fix it. I’ve seen these methods below work on Dell, HP, Toshiba, Acer and most other Windows based laptops. Try These 3 Steps: 1.) While the laptop is turned off, take the battery out and keep your power cord to the laptop plugged in to a power source. Press and hold the power button for up 30 seconds. If you see the screen light up during this process, you can then hit your power button and start windows normally. 2.) If step 1 did not work, then try removing your memory (RAM) card and then re-insert it. Sometimes this will do the trick to reset the memory. Just be sure you remove the battery from your laptop and make sure it is not plugged into a power source when doing this step. 3.) If steps 1 and 2 don’t work, I suggest hooking your laptop to an external monitor. If the computer is working on the external monitor you may have a bad LCD screen or possibly a loose connection to the screen. If you do have a bad screen, those are not very easy to switch out unless you have prior experience doing so. I would suggest taking it to a local computer repair for a diagnosis.
Just a Warning: This will removal all data, music, photos, settings, literally everything, and the entire process is done from the iPhone without the need of using a computer. Back up before beginning if you need any of your personal data again, this will erase everything from your iPhone if you do not have everything backed up to the iCloud or a computer. 1. Launch “Settings” and tap on “General” 2. Scroll to the bottom of General and tap on “Reset” 3. Tap on “Erase All Content and Settings” 4. Enter the iPhone passcode if one is set, and confirm the reset by tapping on “Erase iPhone”
Here is a quick tutorial on how to wipe out everything from your Macbook and restore it to the factory settings. Step 1 To start, make sure that all of your files are backed up elsewhere. When you revert your MacBook Pro back to factory settings, you will also be wiping out all of the data on your hard drive. If there is anything you want to keep, take the time to move it all onto an external hard drive. Step 2 Once your files are backed up, shut down your MacBook Pro. Plug it into the AC adapter, and then boot it back up. Finally, press and hold “Command-R” (the “Command” and “R” keys at the same time) to start the restore process. Hold these keys until the Apple logo appears on the screen, and then release them. You will be taken to an alternative boot screen with a “Mac OS X Utilities” menu. Step 3 In order to complete a system restore, you will need to connect your computer to the Internet. Select “Wi-Fi” from the Utilities menu and find the router you will be using. Enter your Wi-Fi username and password to connect. Step 4 Depending on which version of OS X you are using, your Utilities menu will be slightly different. Look for either “Internet Recovery” or “OS X Recovery,” and select whichever one you find. This should present you with a “Reinstall OS X” option. Click on it, and then wait as your MacBook Pro connects to the Internet and gathers information on your laptop from Apple servers. You may be prompted to provide your Apple account information, including username and password. If so, provide it. In any case, this process will eventually reach the point where your MacBook downloads the latest version of OS X, as well as the standard programs that Apple includes pre-installed on every laptop. Your hard drive will then be automatically formatted, and the computer will restore itself to factory settings. Step 5 Once the reinstallation process is completed, you can either restart your computer, provide your Apple ID information, and start copying your files back over to the computer from your external hard drive, or you can turn the computer off and go about selling it to a new owner.
When you rely on your iPhone for business and its screen goes black while you are miles from the nearest Apple Store, don’t panic. A black screen can have several different causes, most of which you can troubleshoot. In many cases, you can solve the issue yourself, but if nothing works, your iPhone will need to be repaired by a professional technician. Dead Battery Don’t skip the obvious — the iPhone battery could be dead. Connect your iPhone to a wall socket using the power adapter that came with it and then press either the “Home” or the “Sleep/Wake” button. If a drained battery is the cause of the problem, your iPhone’s screen will light up and display an empty battery icon. If the battery was completely drained, the screen may remain black for up to two minutes before the icon appears. At this point, if you see the empty battery icon, you only need to wait for your iPhone battery to charge. Crashed App If you launched an app just before the screen went black, that particular app might have crashed. Press the “Home” button twice in quick succession to see a list of recently apps, each with an icon and preview. Swipe up on the suspect app’s preview to force it closed and then press the “Home” button once to return to the home screen. Launch the app again to see if the problem repeats. If the issue with the app persists, remove the app from your iPhone or contact the app developer for support. Unidentified Cause Restarting the iPhone can fix a number of unidentified problems. Press and hold the “Sleep/Wake” button until the red slider appears. Slide the slider to the off position to turn off the iPhone. Press the “Sleep/Wake” button again to turn on the iPhone. If the screen remains black and you don’t see the red slider, reset the phone. Press and hold both the “Sleep/Wake” and the “Home” buttons at the same time for at least 10 seconds. When you see the Apple screen, release the buttons. iOS Issue If you haven’t had success by this point, your iPhone is likely having trouble with its operating system. Restoring your iPhone to factory settings is the next troubleshooting step. A restore erases the contents of the iPhone and installs a clean version of the iOS. To do this, connect your iPhone to your computer and launch iTunes. If the “iPhone” button appears in the iTunes interface, click “File,” hover over “Devices,” and select “Back Up” to create a backup of your iPhone’s data. When the backup process is complete, click the “iPhone” button, select the “Summary” tab, click “Restore iPhone” and follow the on-screen prompts. If the “iPhone” button doesn’t appear in iTunes, disconnect your iPhone from the cable, but leave the USB end connected to the computer. Press and hold the “Home” and the “Sleep/Wake” buttons simultaneously for approximately five seconds, until the iPhone switches off. Press and hold the “Home” button and connect the USB cable to the iPhone while holding the Home button until iTunes prompts you that it has detected an iPhone in recovery mode. Click “OK.” Click “Restore” and then follow the on-screen prompts. Hardware Fault If nothing works and your iPhone is still unresponsive, the issue is likely caused by a hardware fault and is beyond your power to fix. Contact Apple either online or at an Apple Store. Apple may offer a replacement iPhone or repair your existing one. In either case, you lose all your data that occurred since your last backup.
Your iPhone is plugged in, but it’s not charging. Why won’t the iPhone charge? Is the iPhone broken? Is it time to freak out? Probably not, in fact there are some really common reasons an iPhone won’t charge, and most of the time it has nothing to do with the iPhone itself (unless it was damaged, but more on that in a moment). How to Check if Your iPhone is Not Charging First things first, how do you definitively know if an iPhone is charging the battery or not? When the device is plugged into a power source, look in the status bar for the battery icon. If there is a lightning bolt next to the battery icon, the iPhone is charging. iPhone battery charging indicator If the iPhone is plugged in and it’s not charging the battery whatsoever, and there is no lightning bolt next to the battery icon, read on for the likely reasons and how to fix it. 1: Check the iPhone Charging Port for Debris, Lint, Obstructions One of the primary reasons an iPhone won’t charge is remarkably simple; the port on the iPhone is clogged with dust, debris, pocket lint, or some other obstruction. Something quite small can easily prevent a charging cable from fitting properly into the iPhone, so the very first thing you should do is check the charging port on the iPhone and look for any crud or build-up in there. See some lint or some other wad of gremlin or crud? Get it out of there, preferably with something like a Q-Tip, toothpick, or a dry toothbrush. If you have a can of air, blowing it in there can help too. Check the port if iPhone is not charging Once the charging port is cleared out, try charging it again. Seriously, junk in the port is common (that applies for Macs with MagSafe too) and it can prevent a device from syncing, charging, or getting any power at all. It probably works now, right? If not, keep reading. 1B: Wait, Check the Cables Plug End too! Before moving beyond this one, be sure to check the plug end of the cable as well, sometimes it can accrue stuff on it that would prevent the connection from forming as well. Thanks to several commenters who pointed this out as a possible reason why a cable wouldn’t charge properly. 2: Change the Wall Outlet or USB Port Plugged Into The next most common reason an iPhone won’t charge is because of where it’s actually plugged into. Sometimes the wall outlet itself isn’t working or the light switch is turned off, so if you’re using a wall charger then change the outlet. If you’re charging the iPhone from a USB cable connected to a computer, sometimes the USB port on the computer itself is the problem. Try another USB port on the computer, PC or Mac doesn’t matter, that often fixes the issue too. Oh, and another perk to using a wall outlet is that it usually charges the iPhone faster too. Sweet. 3: Check the USB Cable for Damage Damage to the USB charging cable will prevent an iPhone from charging. This can be somewhat obvious in some situations, and if the cable is fraying or torn, well, there’s your problem. If your cable is damaged, you need a new USB cable to charge the iPhone, it’s that simple. Fortunately, you can get cheap Amazon Lightning USB cables that are certified and they work great and are quite durable. * Another potential USB cable related issue that can make an iPhone not charge the battery are cheap knock-off cables that are low quality. You’ll usually encounter an error that the cable is not certified on the iPhone (or iPad) itself if this is what is causing the charging issue. 4: Reboot the iPhone Rarely needed, but sometimes a simple reboot can resolve a software issue that basically refuses to acknowledge the device is charging. This is somewhat rare, but it can happen. So if you’ve tried all of the above and the iPhone battery is still not charging at all, force reboot the iPhone by holding down the Power button and Home button until you see the Apple logo, it may help. 5: The iPhone Was Damaged and Won’t Charge If the iPhone has been severely damaged, it often won’t charge. Usually a simple screen crack won’t make a difference, but if the iPhone was run over by a dozen cars or fell out of a 50 story window, it’s probably toast and won’t charge because the hardware is damaged. Another very common reason for charging and power problems is water contact, or dropping an iPhone into liquid and not drying it out properly. If the iPhone has sustained excessive water damage and was not dried out properly and sufficiently, the iPhone battery is often destroyed, and other electrical components in the iPhone can also be damaged as well, which will completely prevent the iPhone from charging. Fortunately this is usually pretty easy to determine, because if your iPhone took a deep swim and it’s now not charging the battery, that’s almost certainly the reason why. Try drying it out for 72 hours or so in silica or rice, it could revive it, otherwise you may just need a new iPhone or hardware component to fix the problem. Often if an iPhone is physically damaged, either by blunt force or by liquid, the iPhone won’t even turn on or respond to normal fixes for that like leaving it plugged in for a while let alone charge when connected to a power source. If the iPhone is broken, well, you’ll need to take it in for service, or get a new one. Those are the most common reasons an iPhone won’t charge when connected to a power source, so if the battery isn’t moving at all, you don’t see a charging indicator, and device isn’t working, try the above steps before going further.
A family member just gave me their Toshiba laptop and told me he was just getting nothing when turning it on. So when I got home and powered it on I immediately got a black screen with a blinking underscore at the top left of the screen as pictured below. My first instinct tells me it has something to do with the hard drive. Either the hard drive itself is not getting a stable connection, some sort of memory error – or worst case scenario, the hard drive is faulty and no longer works (which means it needs replaced). Luckily there are a few things you can try that may lead you to a quick and easy fix. Steps To Follow: 1) Un-plug your laptop. 2) Remove the battery 3) Hold the power on button for atleast 10 seconds (This drains the CMOS Battery and any remaining power hiding in the system) 4) Access the bay where your HDD (Hard Drive) is plugged in, and remove the HDD. 5) Plug in external power and power on. At this point windows should attempt to load normally but since the HDD is removed it will stop and give you an error and a prompt. 6) Turn off laptop via power button (Hold it if you have to, windows won’t/can’t load without the hdd so you’re not damaging the system files) 7) Unplug the external power, and drain CMOS reserve again 8) Re-insert HDD, battery, and external power in that order. 9) Power on and hopefully successful return to normal operation If this does not work after trying it a couple of times it is likely that your hard drive needs replaced. In my case, it was a faulty hard drive which I replaced for under $50 by ordering it on Amazon.
