Was saving this PC worth it after being scammed by a customer?? Hp Omen 25L!!

[@steventechno]

I think using IPA is a good solution. The fact that it not only does a great job removing dirt, but it also evaporates very quickly. Recently I did acquire an old beast and it would not work at all. Hit the power button and it would shut off 1 second after pressing the power key. I pulled the board out, and there were dust bunnies on the back which I assumed created a short. I cleaned it up and wouldn't you know it? It works completely fine. That was just with a good brushing.

[@LesCalvin3]

I like 91% usually. It evaporates quickly, but not too quickly like 99%. I'm just careful not to expose the plastics to it too much.

[@Arachnoid_of_the_underverse]

[@doug4short]

WTH?.... I'm an electronics tech (10yrs) and retired USN electronics tech (20yrs). Isopropyl alcohol (IPA) is a VERY common pcb cleaning solution. Now it should be a high purity (99/98%) and not the generic rubbing alcohol (70%) from the local pharmacy. Little tid bit of knowledge, IPA (at least the ones with high purity) do not conduct electricity.

[@curtis.albrecht.79]

AT2 (HSL-41, 1988 - 1992) here. I used to "wash" my hands with copious amounts of Trichloroethelene after avionics maintenance. Worked great! Causes cancer. Today, brake cleaner and/or WD-40 is the solvent of choice, for cleaning my computer parts. But, yea. PURE IPA also works well... Drugstore 70/30 has a LOT of water, which can damage computer parts/electronics.

[@strawberrysherbet96]

What about 91% gotta use that cause Walmart never sells 99%. It works for me and I have tried 70% once which works too but I let it dry overnight cause it’s pretty close to 50% too lol.

[@doug4short]

@@strawberrysherbet96 Gotta work with what ya got. I'd do like you already are and extend the drying time or give it a bit of a bake. The lower purity ones will tend to leave a film though (this may or may not bother you depending on what your cleaning). Cheers.

[@soupdragon151]

Pure water is non conductive as well its the ions in it i.e. impurities that conduct

[@HardWhereHero]

​​@@strawberrysherbet96it's fine to use the '91% especially if you make sure it's dried out pretty well. Take the component and kind of fan it in the air, that will throw off any unevaporated liquid. Just don't pull a Linus and launch it across the room.

12:50 No doubt it can boot without thermal paste, and it can boot if the processor cooling fan isn't running, but if it doesn't have good contact with that heat sink, I think that the processor can fail very quickly. Please tighten those screws.

[@falkwulf3842]

In your first video, at 15:10 you were asking about the pattern on the back of the board. That is a tale-tale sign that the board has been HOT!!!. I used to work for a repair shop that had some success reflowing solder and fixing a dead board using an oven. It does work some of the time, of coarse there are videos on YT about it, and because of that many people try it themselves to varying degrees of success. All that boards that we reflowed using the oven looked nearly identical. Why you might ask. It is the rosin cooking out of the 60/40 solder.

[@soupdragon151]

It tends to be temporary in my experience it looks like its worked only for it to break down again maybe weeks maybe months later but its will happen in the not too distant future

[@Thomas_Tolson]

I like the content bud! I own a repair shop myself... one thing with factory systems like these, I usually leave the board plugged into the case. If the case has a power switch that illuminates, like the "beep codes", they will blink and give you the same code as a beep code.

[@andrewober]

I purchased a 25L with similar issues. I'm fairly confident that Windows update pushed out a bad bios update that bricked the motherboard. I'd bet money that that is what happened here.

[@robparker2613]

Hey man your video just popped up on my channel and I watched it! I just wanted to suggest that many times when I have a bad motherboard That doesn't work and doesn't have noticeable damage the problem ends up being a corrupted bios! Usually, someone tried to do a bios update and something went wrong! I can't tell you how many MB's I've saved just by flashing the bios of the MB through a programmer! Pretty easy to do and you can save or make yourself a good chunk of change!

If the CMOS battery is under 3V its a good idea to replace it.

I like my C3032s above 3V at all times. They are usually fine until its 2.7-2.8 but i have seen batteries reading above 2.9V that were causing issues.

[@fxgamer-11yt]

cleaning the watter damage that you found behind the socket mounting bracket might of brought the mobo back being its corrision is conductive it can short the power turn on sense for the cpu and have a false turn on and it wont send power to the cpu

[@fragalot]

some motherboards have a BIOS setting for behavior when power is restored, and you can have it just boot up. Problem you've replaced the CMOS battery many times so that setting ought to have reset by now. I think the board is kaput since it doesn't even give beep codes. If it was a working mobo, it would still give beep codes if it had no CPU and/or no GPU.

[@OldChevy79]

I use robing alcohol and wind decks 1/2 and 1/2 to clean PC and parts

[@gerydblackmore5484]

always best to check the battery in circuit if possible, anything below 3.0 volts, replace.

[@cracklingice]

Restore power after AC loss is a setting in the bios that will cause the machine to turn back on if there's a brown out or whatnot.

[@JohnnyT002]

I had the same problem when I got my first computer back in 1999 from a clearing house company. I didn't know better back then and I didn't realize it was a used PC . It stopped working after a week and I sent it back when it came back it worked for a few days . Later on my friend look at it and there was no power going to the motherboard. Then I took it to a shop in Manhattan and they changed the motherboard and it worked after that.

[@alibro7512]

Before you showed the water damage I was going to ask if you were able to confirm all jumpers are in the correct position? Your customer probably had a go at cleaning up the mess but missed the bit under the CPU.

[@dwcinnc]

I just purchased one of those keyboards, love it. Fortunately, water only damaged motherboard.

[@erintyres3609]

Visual inspection should be somewhere near the top of your list. Does the board have any water damage, anything burned, any leaking capacitors, any components broken off, any traces cut, any bad connectors, etc. Some damage can be repaired. Update: Yup, you found water damage at 15:38

Hey man, love you show. I have been doing computer repair/upgrades since the early 90's, before windows during the DOS days. Let me help, as far as batteries goes, the 2032 is a 3.2 volt battery new, any voltage below 3 volts replace. When you are trying to figure CPU vs M/B which is bad. In my life I have only had one CPU bad. Mostly look at motherboard when you have to pick between the two. Asrock make great motherboards, I have tried them all and finally ended up choosing Asrock, they work.

Cean up on the back of og mobo where the corrosion was w alcohol & a brush & install a new mobo battery & try it again. It might come back to life...The psu will not start if a short like corrosion exists so it may work after cleanup of corrosion

[@NEFeldman]

So for my back up PC, it’s housed inside a Lian Li PC08WX in black which was the predecessor to the PC011 versions. The case is fully Aluminum with tempered glass. Anyways, this was my main case for about 4 years before moving my main rig into first, the 011XL, then 011EVOXL. I have a Gigabyte Z270N Gaming 5 Mini ITX Board currently in it now. The only positive over what you did is it has the NVMe slot on the back of the motherboard. I was totally thinking to swap to a full ATX board, but for the purpose I’m using it for doesn’t fill the need. No extensions were necessary in the case as well.

[@ItIsNot1984]

Get a supply of 1 pin dupont jumpers and you can extend any of those headers. Just gotta be careful not to screw up the pinouts. The jumpers are super cheap.

[@Chris-ji8jw]

Yeah, i thought it was, actually, the motherboard. I just had a hunch; i guess. Thanks for sharing!

[@Wint3rshad3]

When diagnosing motherboard problems I like to run a test without any ram installed because I know the mobo will yell at me if there is no memory installed and at that point you know its at least doing checks and the speaker is working if there is a speaker installed. Also put the board on a flat surface and give it a good look around to see if its bulging, warped or bowed in anyway, ive had some that would be warped in certain areas and just putting pressure on said area would make them fire up to life.

[@michaelshifflett6597]

just something that might be an issue is some motherboards are sensitive to which slots are populated by the memory sticks.

[@brokenpatriotvideos]

FYI. I was at Dollar Tree and saw those cmos batteries. I was kinda shocked especially since i just bought 2 at Ace Hardware for 10.00.

[@mikeelek9713]

I would guess a dead or damaged CPU and then a bad mobo as the No. 2 reason. Regarding isopropyl alochol, I've seen others uses this. I've done it myself. This works well as a cleaning agent, because as you know it evaporates quickly and doesn't leave behind any residue.

[@gdjaybee742]

You can get an M.2 to PCIx 4x slot adapter and reuse that M.2 drive on the new mobo. The mobo is new enough that the BIOS should support M.2 on the 4x slot via adapter.

[@malem67]

Auto start is usually a BIOS option the setting is called something like power on at AC restore .

[@softtaco8264]

Invest in a heat detector...find the hotspot...it is NOT supposed to turn ON by itself. The guy that owned it was prolly tinkering inside while it was powered and shorted a component on the motherboard

[@mikesgarage394]

I have had the auto power on when power was removed while the board was learning a new configuration, i.e. after cpu or ram swap.

[@troylaquerre5466]

Old school Hewlett-Packard tech here. If the computer does not post Take everything off of the motherboard one at a time. Take one stick of ram out and try to boot it. Then go to the expansion cards.

My Asus board died exactly 3 months outside of the 3 year warranty so it was a good guess. Definitely would guess mobo over cpu all things being equal. My previous Asus board lasted 10 years before it died.

Congratulations on over 20k subscriber's!! I am pretty new and checking out some of your videos.

[@TheRepeatloader]

just a quick note- power automatically comes on.. if power switch still works- its usually chip related, if the power switch does not work-- its powersupply or shorted motherboard (usually) ... just a fast way to look for the issue- I was going to say it was motherboard but you found the problem..(motherboard) :) great video

[@TheGameBench]

Okay, I went back and watched the other video again as a refresh on what people were complaining about, and I'm sorry but if you think spraying IPA on a motherboard and cleaning it with a toothbrush is bad... then you're probably not the "computer technician" you think you are. You cannot damage an electric circuit with a neutral liquid if it's powered off, and there are liquids that you can spray on it that can't damage it even if it's powered on. For applications where they can't have downtime, they take a pressure washer to industrial power equipment and servers... while they are powered. This is a special blend of chemicals that are not conductive, which normal people won't have, but you just need to remove power first and fully dry it before powering it on again. As for the toothbrush... nothing wrong with that as long as you aren't ham-fisted neanderthal and you just get overly aggressive. I've brought so many mobos back to life use this method. HOWEVER, I would absolutely remove the CMOS battery first. Also, I have worked for several PC repair shops and I run my own now... you need to know the laws in your state and how this is handled, but you just can't be expected to hold on to their computer perpetually. You eventually have the right to sell it if they don't ever come back to pick it up or they refuse to pay.

[@mtzkustom7818]

Ham-fisted neanderthal got me. 🤣

[@gerydblackmore5484]

I believe Greg Salazor just did a build with that mother board, his was an Asrock with no m.2 aswell. In my experience when it comes down to the MB or the CPU on a desktop system its generally the MB.

[@Woodwerker]

I was thinking MB was bad - I have only had one CPU fail in my whole life and I have been building PCs since the 1990s.

[@falkwulf3842]

Same here, Ive been building since the late 80's and I can count on one hand how many bad CPU's I've come across. 99.999% of the time its the mobo.

[@JetScreamer_YT]

I used to repair computers here and there. I had to stop. A couple people (after I fix their computer for free) blamed me for breaking thier stuff. I made sure their computers were operational, and never took a job again. It's a shame, because I have talent, and I love doing building and repairing. I like that you're very thorough, and protect yourself. Doing that would have helped me back in the day.

[@lain__d]

You should have tried turning it on without memory/graphics card plugged in at all. This would create a situation where the motherboard SHOULD beep for a known error (no graphics card/no memory) and you would be able to tell if the motherboard was doing any sort of POST tests at all.

[@Addeatt]

I had the same issue with a motherboard, I would spray a ton of IPA and clean it up 2-3 times. Mine ended up working just fine.

[@Roobotics]

I'd detour and see if that water damage can be resolved before following through with the swap, gonna have to mess with all the cables, plus it's far more resellable with original mobo as a SKU and all the features there like m.2 etc.

[@emmetthorath4542]

Awesome. I thought the motherboard. Its almost always the motherboard or bent pin in my case. Learned the hard way. Start with the cheap fixes first.

[@Voidsworn]

I often use Vaseline as test thermal compound. Also, it tends to absorb old thermal paste from the CPU and heatsink, cleaning it a bit when I wipe it off.

[@lsimpson50]

Good result, nice video.

[@cecilb7927]

I use IPA cleaning PCBs a lot. It with power and battery removed conductivity isnt much of a problem and it dries fast without leaving resudue. Distilled water would be fine as well, but alcohol is a better solvent for crud. I have had HPs and Dells that turn on as soon as they have power. There is normally a setting in the BIOS for that. I also like using a known good CPU, I keep a celeron or Pentium from the different generations just for troubleshooting, they are cheap, maybe $15 each used.

[@LordLeeCH]

A good test is to unplug everything but the cpu. No video, no ram, etc. You should get post beeps for ram and video. If you don't get any beeps, it's motherboard.

[@NiPPonD3nZ0]

I've stoped unglueing those cooler supports and swapping the hole backplate assembly... a T25 and 3 screws is easier than dealing with that stupid glue!

[@twizz420]

I've had the bristles from an "ultrasoft" toothbrush get under surface mount components and rip them right off the board before. That's why I only use a very soft paintbrush now. Iso is fine to use, but not rubbing alcohol. If you can't get at least 99% iso then don't use it. In 70% iso, the other 30% is water. That's why it's bad to use rubbing alcohol. If you drop a phone or something in water, don't turn it back on. Dunk it into a container of 99% iso. The iso displaces the water, even if the water has gotten into the circuit board(s). Also you can use chlorine-free brake cleaner as well. It tends to work a little better because it's pressurized.

[@johnhudson7055]

Did you look for the BIOS reset jumper? It is an HP afterall? I'm betting bent pins in the socket. Did not see liquid damage coming.

the only thing is I dont know if you tried it is reseating the cpu but if its the motherboard coming on its most likely something in bios or the motherboard burn I seen that too

[@justinhart-nishikawa3105]

I believe they actually wash circuit boards with something like isopropyl alcohol at some point in the manufacturing process. I actually washed a shitty old PSU in my bathtub with soapy water before, and it was fine. I made sure to discharge it and sprayed it with electric parts cleaner after and blow dried it and let it sit outside on top of an ac unit fan on a hot, dry day for good measure.

[@soupdragon151]

So long as you remove all traces of water immediately afterwards it should be fine its letting water stand around that causes corrosion and of course any evaporation residue

[@cuistotadomicile]

Since you find out what was the problem on that board I would totally clean the board with IPA and I would test it again to see if that fix the problem

You should ask for the diagnostic upfront. Let them know you will apply it to the repair. That is common practice. Even if you are not a professional, I assume you have a business license.

[@Gaspode-uj8jt]

Regarding the original Omen PC powering up when the PSU was turned on, I have seen this behavior in many KZbin videos featuring HP and Dell systems. Would it be worth it to try a PCIe to NVMe adapter in the X1 slot? By the way, you make great videos. Looking forward to the next one.

They would've had to have been in a pretty small room and/or vaped really heavily to do that kind of damage to the motherboard (if vaping was the cause). As for washing a motherboard/parts in a dishwasher, it's effective on heavily dusty/grungey boards but shouldn't be the go-to solution since water deposits could potentially get trapped under the tiny electronic parts. Heated drying is an option, however, since the temperature isn't enough to cause any problems itself, but mineral deposits could remain can cause problems. Seeing the dust that was inside of it though (in the first video) makes me glad that I clean my gaming computer at least every 2-6 months.

Also had this tiny short near the sio but taking the shorted part off and putting it back fixed that.
