I went in expecting a board repair job on this one. Was actually much simpler... Spoilers below...
Took out mobo, removed BIOS (aka CMOS) batt for a few mins.

Thank you SO MUCH! My laptop showed no signs of life, but with the help of your video, I checked the voltages and resistances, reinserted my ram, and unplugged my cmos battery for a bit...and it lives! At least, it now gives me an amber/white blinky code that says i need to replace the cmos battery entirely. But i will now be able to buy one and install it no problemo! Thanks again 😊

A giant ship engine failed. The ship’s owners tried one expert after another, but none of them could figure but how to fix the engine. Then they brought in an old man who had been fixing ships since he was a young. the old man immediately went to work. Two of the ship’s owners were watching, hoping he would know what to do. After looking things over, the old man pulled out a small hammer. He gently tapped something. Instantly, the engine lurched into life. He carefully put his hammer away. The engine was fixed! A week later, the owners received a bill from the old man for $10,000. “What?!” the owners exclaimed. “He hardly did anything, ask him to send us an itemized bill !” The man sent a bill that read: Tapping with a hammer………………….. $ 2.00 Knowing where to tap…………………….. $ 9,998.00 Effort is important, but knowing where to make an effort makes all the difference!

Mate you are a life saver! I had this exact issue. I followed this breakdown/troubleshoot video and the laptop was brought back from the dead. Amazing! Thank you.

@AlvarodeJuanRodriguez 5 месяцев назад

you're a life saver my friend. I've had my dell xps 16 9560 with this problem, jus sitting in the shelve, for about 4 months. Today i decided to send it to a repair shop, but first, i wanted to look it up on the internet. Found your video i decided to try and do the bios reset and now i have a working computer again. thank you so much.

@AlexKiraly 2 года назад

Thank you SO MUCH! I've replaced the battery from 56 Wh to 87 Wh, and my 9550 would not turn on anymore. Neither would it with the old battery. I came across a forum post linking your channel and I thought to myself, "finally the solution". This is the first time I actually had one of these weird issues that was solved with a bios reset. I did not remove the video connector, instead i propped the mobo at 90 degrees and removed the battey, waited around 5 minutes and put it back. Reconnected the power adapter like yours, and the power light did come on. After connecting the battery too, the charging LED was blinking three times orange and one time white. Held the power button down for a quick reset, did that a few times. Third time it came right up and everything has been fine since (this was 2 minutes ago though). Many thanks!

@stevemercure902 3 года назад

I've been repairing computers as a career for many years now. My best guess goes right along with you, that it was removing the battery from the BIOS chip that cleared some kind of corruption. I have seen a laptop or two fail where simply reseating the memory chips also returned the system to life, but not that often. Thanks for an enjoyable video.

Just fixed a Dell XPS 15 9560 with no power thanks to your video. You have the best video out there. I can share the pictures but it seems the cmos battery cables were too loosely installed and had actually wriggled out unplugging it. A board screw was actually crushing one of these cables to the point it nearly severed it. After patching that wire and making sure the wires were more neatly tucked underneath the board assembly - it boots up perfectly. Thank you Adamant!

@dash8brj 3 года назад

Sometimes just removing a ram module, starting the computer, then shutting it off and putting the ram module back saves having to remove the board to find the cmos battery on Dells. Changing the amount of system ram will often force the bios into a "soft reset" - doesn't reset all the settings, but enough to kick the laptop back into life.

I was just about to spend possibly some hundreds of bucks to have someone fix it for me… After watching this I was still skeptical that by merely reassembling stuff you can solve the problem. Nonetheless since the warranty of my device had already expired there is no harm in giving it a shot myself, and it works! Thanks you so much for the instructions!

@kalpeshjogi5551 3 года назад

Exact same problem. No power, no response. I followed same set of steps. Disassembled everything, put everything back together and hurray it started working. I think it required cmos reset, which was achieved by disconnecting the cmos battery(coin cell battery), keeping it disconnected for few mins and connecting again. After putting everything back together, it started receiving power, but it was showing amber and white light sequence on the front indicating memory problem. I inserted RAM modules one by one and then it all started working. Thank you so much.

@lemccoy 2 года назад

Just had to do the same. I only disconnected enough to lift the motherboard up about 90 degrees and pull the cmos plug. Left for 10 mins, put back together. Had to do the 30 second power button hold as well. Then reset time in bios and disabled sleep mode in bios. Windows 10 started up then locked and slept, I guess it failed in the middle of that process. Power button again and it seems to be back to normal. Many thanks!

I once brought back to life an Asus (Desktop) system by removing the CMOS battery. The thing is, this removal did NOT work immediately like yours. (Yes, I tried several times, battery in and out following procedure) I was convinced I was going to scrap the MB after trying everything I could think of to get the thing to fire up. NO JOY, so I pulled the battery (I'm cheap), thinking this MB is going in the trash. Next day I decided to give it one more chance, and put the battery back in fired it up, and Wha La !!! The dang thing came to life! I could NOT have been any more surprised (or happy) than I was. This "fix" was something you never forget

@mdc1802 Год назад

Thanks for the vid mate. I watched this yesterday (after I ordered a new power port) & my laptop started working again. Put it back together & it worked for a while then died again so I unplugged the battery and just run it off the power adaptor. It still shuts down now and then but I managed to transfer my files to a hard drive. It's only 2 years old so it's pretty disappointing. It's a good laptop, fast & powerful, when it's working and the keys aren't breaking. Won't be buying a Dell again, but they all have their faults I spose.

Whenever I find these sort of issues like the laptop comes back after a CMOS reset, I always update the BIOS. Those errors are almost all the time due to bugs in the BIOS which the manufacturers often state as "fixed system does not intermittently start".

Ram modules sometimes buildup static for some reason.

It was probably something in the machines that caused it.

On at least two occasions I've had a "no power up" PC start working again after I simply took it apart and reassembled it.

On the second, I still have no idea what got healed when I put it all back together.

I think Sorin on " Electronics repair school" channel would of described this as a stuck bios, fixed by pulling the CMOS battery. He also shorts the positive and negative terminals of the CMOS battery connector on the motherboard after he removes the battery to complete the reset rather than leaving it for a few minutes...much quicker!

@marcellipovsky8222 3 года назад

Yup, he call it "stuck start-up chip". I had a Toshiba Portege once, which did not boot. I did all the reset things, but it did not help. I haven't had the knowledge I do now thanks to Grant, Sorin and Northridge Fix. So the laptop was left on the shelf to to look at later. I've reconnected it after about 3-4 months later and what happened? It booted just fine. I only had to set up the BIOS. Till today, the laptop is working just fine. Other case in another Toshiba laptop (also portege, but newer) was a batery not charging problem. I thought the battery got dead so I bought a replacement. After a week, the client started to complain about the battery life, so I opened the laptop again. Guess what happened. The battery got swollen and I had to return it. For the sake of testing I still had the old battery so I reconnected it and guess what, it started charging! It did charge up to 70% of its original capacity. bare in mind that the battery was about 2-3 years old. Till today (a year or more later) the laptop and the battery work just fine. (with the expected battery capacity degradation)

@hardies1 3 года назад

One simple thing that you can try with a laptop that is acting like this is to disconnect the battery and the charge cord, Then press and hold the power button for 30 seconds. Release the power button and reconnect the battery and power supply. Then try powering up the system and see what happens. What this does is to drain all of the residual electricity from the components on the motherboard essentially resetting the board.

@FireballXL55 3 года назад

Nice video as usual, I have had a few like this and I like you are not totally sure, but I hazard a guess that the power management gets confused and won't let it out of standby. I assume they have just shut the lid rather than power down. Did you notice what the main battery state was straight after you rebuilt, because I wonder if the main battery has gone too low for it to restart from standby, and confuses the APM.

When their voltage drops below 3 volts, they don't have enough power to properly power the bios chip. Weird things start to happen, like boot issues and clock not keeping time correctly. It's always a good idea to check the easy stuff first. I think when you removed the battery, it reset the Bois.
