How To Fix Any Laptop - Wont Turn On, Wont Open, Turns Off Right Away, No Power Solution

hey guys jamin here pc monkey i'm bringing you another do-it-yourself computer video today in this video i'm going to take you through the entire troubleshooting process of a computer that either won't start at all or starts and then turns off right away before ever reaching that initial startup logo screen if your problem is something else you're going to need a different video a couple commonly misunderstood issues is if your computer starts you can hear the motherboard clicks you can hear the hard drive clicks uh the fan turns on but the screen just stays black that is a video link below in the description that'll be a computer turns on screen stays black fix also the other issue that may be misunderstood as this one is if your computer starts you see that initial startup logo screen but then it shuts off or then it gets stuck that's a bootloop fix video that'll again be in the video links below this video is specifically if a computer starts and shuts off right away before the logo screen or if it doesn't start at all so to start with the first thing we're going to try is a static discharge procedure some people refer to it as discharging the capacitors whatever you want to call it maybe you've seen this done before if you call a warranty repair line this is the first step oftentimes they have you do to fix your computer so to start off doing this you're going to unplug your charger flip your computer over and take out your battery most likely you'll have a computer sort of like mine where there's a switch maybe two switches that you press or slide to remove your battery easily if you don't have a computer like that maybe your battery's inside your computer at that point check out a disassembly video a tear down video or a battery replacement video on your exact model computer that'll show you how to open up your computer get inside and either remove your battery or just unplug it from the motherboard once that's done we're gonna hold down the power button for one minute after you've held it down for a minute we're gonna put your battery back into the computer or if you have an internal battery plug it back into the motherboard and then we're gonna plug your charger back in try turning on your computer if your computer turns on at this point you've identified the static build up as the reason why it wasn't working try to limit the use of your computer around sources of static so don't use your computer in bed around blankets or pillows don't let your cat sleep on it try to limit the sources of static also a big one make sure you're not plugging your computer directly into the wall make sure you're using a surge protector a healthy one if this problem persists and you have to do this procedure every time you have to turn your computer on consider replacing your surge protector your battery and your charger one of them could be bad if your surge protector is reasonably old i'd replace that first if you want to think about replacing your charger later on in this video i'll show you how to test it to make sure that it's working properly if you've confirmed it's working properly then consider changing your battery if your computer is not turning on at this point unplug your charger again take the battery out again hold the power button down for another minute after you've held it down for a minute we're going to put one of them back in but leave the other one out so we're gonna put let's say your battery back in leave the charger unplugged try to turn your computer on if your computer turns on we've identified that your computer is good the battery is good the charger is what needs to be replaced sometimes the computer can sense when one part is bad and it'll stop itself from turning on to protect itself from being damaged so again if your computer turns on at this point replace your charger if it's not turning on we're going to repeat the process only this time we're going to leave your charger in so we're going to take your battery out hold the power button down for another minute once you've held it down for a minute we're going to leave the battery out and plug your charger back in then try to turn on your computer and you probably guessed it if your computer turns on at this point we've identified your battery as being bad replace your battery if your computer's still not turning on then we've eliminated this test we'll move on to the next test the next test is going to be checking your ram for any ram issues so to do that first thing you want to do unplug your ram plug it back in it's called reseeding an item so make sure that it's not just loose if that doesn't work we're going to actually test to see if one of your ram sticks is bad to get at your ram most likely you'll have an easy access panel or door on the bottom if you don't have an easy access panel like i do you'll have to take off your entire bottom case if you have to do that your best bet is to search for a tear down or disassembly video on your exact model computer that'll tell you exactly how to get into the bottom case and it'll limit your chances of breaking anything if you can't find a video here are some pointers first remove all the visible screws then remove your battery if you have a removable battery watch out they sometimes hide screws under there they also sometimes hide screws under the dvd drive and sometimes they hide screws under the bottom feet so watch out for all those places if you have an easy access panel then you're in luck it's a lot easier i'm just going to remove a couple screws and gain access to some commonly used components so there's my ram this is a very normal way that you'll see ram in a laptop there'll either be two ports for ram or one port if you only have one port and one stick of ram you'll have to buy another working stick in order to do this test if you have two sticks they'll generally be on top of each other or side to side now the way to test your ram is to take one out at a time they're usually held in by two spring loaded arms on either side you pull those apart and the ram sticks release like that and then you can slide it out so you take out one stick and you try to boot your computer again if your computer turns on it means that stick is bad that stick is good and you have to replace that one if you want help in finding compatible ram look below in the description there'll be a link on how to buy the right ram because not all ram is compatible with all uh computers if it still doesn't work at this point then you take out the other stick and you put back in this one and then you try booting your computer again and then same thing if it turns on then this thick is bad and the stick was good after the ram test you didn't find anything wrong with the ram and your computer's still not turning on we're going to move on now to what's called a bios reset we're going to unplug the cmos battery on your motherboard leave it out for about 20-30 minutes and then plug it back in that'll reset your bios and eliminate any errors that could be causing your computer to not turn on okay so your computer may not look exactly like mine or maybe it does i have one main bottom case that needs to come off to get inside you may have several easy access doors that have to come off first if if you want to be super safe about how to get into your computer look up a disassembly video on your specific model so you know what you're dealing with but most computers you'll have to remove your bottom screws watch out for any screws under your battery watch out for any screws under your dvd player some computers may have screws under your rubber feet and some computers you may have to take off your keyboard and undo some screws under there first in order to get this panel off so again either check all these places if you're comfortable or if you want i'll look up a disassembly video on your specific model so this is your cmos battery it's a little round component here it looks like a watch battery inside it's wrapped in black electrical tape and it plugs into a port another common cmos battery presentation is on this motherboard here that's another common way you can see a cmos battery on a motherboard so if your cmos battery looks like mine in my lenovo all you would do is is unplug it from the port don't pull on the wire just put your fingernails on either side of that thing and slide it out a little at a time wiggle it out and then you've unplugged it so that's a bios reset leave that unplugged for a while and then just plug it back in if you have this other kind of cmos battery here uh the way to get this out there's a spring here that holds it in and a spring underneath here that pushes it up so we're going to want to push this battery back and up be very careful though because this right here is very breakable if that plastic part snaps off then your battery won't be secure so just be very careful push in and up like that and it comes out like that and then again you would leave it out for a time and then you would slide it back in and snap it back down in into place after doing the bios reset if your computer is still not turning on we're going to test your charger now i know we tested it lightly at the beginning but we're going to actually physically test it with a multimeter now to make sure that it's actually working properly and consistently so i'll show you how to test your charger now if you have one you probably know how to use it if you don't have one they aren't that expensive i think i got this one for not that much more than 20 u.s online but to show you how this works i have my universal adapter here and i have it set to 19.5 volts which is a very common volt rating for laptops i'm going to show you how to test it to make sure that it's working properly when i say setting it to volts i mean this one right here the v with the solid upper line and the dotted lower line not this volt with the squiggly line it'll be this one i'm then going to take the other end of my charger carefully take off my probe covers make sure that they don't touch now i'm going to put the black or ground on the outside of my charger casing and just hold it right on the outside like that because that's not where the power is flowing through on the outside then i'm going to take my red probe and put it on the inside and i'll zoom in and show you what i'm doing so this is my multimeter here's my adapter here's my adapter end that i'm going to test to make sure the right bolt is coming out and here are my two probes so i'm going to take the black probe or ground hold it on the outside so it's touching the outside casing and i'm going to take my power one and put it on the inside as you can see it's reading 20 volts on the multimeter which is close enough to 19.5 but what you'll notice is that it's nice and steady it's not dropping drastically or going up drastically it's a steady 20 volts which is a healthy charger now to show you what i look like if it's not the right voltage i'm going to take my universal adapter and it's at 19.5 now i'm going to switch it all the way down to 15 volts for a 15 volt a computer now i'm going to do the same test take my black probe on the outside touch the inside with the red one as you can see right there now we drop down to 15 volts so if your charger is supposed to be 19 volt and you're getting at 15 volt then it's not healthy or if you're not seeing a steady amount like this if it's going down drastically or up drastically again that's not a healthy charger after testing your charger you've confirmed it's working properly we're kind of left at this point with a motherboard issue we've tried the static discharge that didn't help we've tried checking your ram that didn't help we did the bios reset that didn't help and we've confirmed your charger now is working correctly we're left with your motherboard for those of you who are a little more tech savvy maybe you know how to solder or desolder things from a board check out the video link below in the description that'll show you how to test your power jack with a multimeter just like we tested your charger to make sure that the charger is delivering the right power to the power jack and the power jack is delivering the right power to the motherboard again that's only for those of you that can solder because if you find your power jack is bad you'd have to remove it and solder a new one onto your motherboard for most of us we're not going to do that for most of us if the power jack's bad the motherboard's bad so for a motherboard replacement that's kind of the most involved repair you can do on a computer check out a motherboard replacement video or a teardown or disassembly video on your exact model computer so you know exactly what you're looking at when you get in there how to unplug everything correctly and how to plug everything back in correctly so hopefully this helps you identify the issue with your computer not turning on we've identified all the possible causes taking you through all the steps at this point if nothing's worked you've identified the problem it's your motherboard so you will be able to fix your computer if you have this problem any questions or comments if you got lost anywhere or if you think you have a unique situation check out the frequently asked questions below in the description uh if you don't see yours there leave me a comment i do get back to you guys
