Moral of the story, always check the devices input voltage and current ratings lol. Good to see you back!!
Quite useful actually. Reminds us the importance of reading the actual power requirements.
Being a while, good to see you. important information, I remember a job I did weeks ago where the charger the customer brought with it is greater than the power specification of the laptop which spoilt the board, not repairable.
You mean the voltage provided by the charger, right?
It could do with a 6v zenna diode cathode connected to the socket +, the anode end goes to the first mosfet via a transistor and resistor.
Keep the mosfet off if the voltage is above 5v.
Thanks for the warning. First I've ever seen a 5V laptop.
google Chromebooks are also 5 volts..
Me neither, definitely a wake up call to triple check the voltage 🤓👍
At 4:33 you can see that it already comes up after connecting the ground and at 4:34 the Logo shows up before connecting plus. It was just starting up from the first attempt of removing the battery and would have needed some more time
Worked on so many Lenova products and so many have no protection at all.
Got qualified as a Lenova service engineer through work.
They have a huge amount of stuff missing to bring the costs down.
Teribble brand new 5% have dead HD within a month.
pointless video? no information about tech stuff are pointless. your video is much appreciated
That's got to feel gut wrenching to see smoke coming out. I'll try to remember that the next time I go out on a computer housecall. PS. I've missed your shows for the past 6 months, don't know why TH-cam has not been showing them to me when your video's come out.
"don't know why TH-cam has not been showing them to me when your video's come out" - Because their recommendation system is utter garbage, that's why.
Surely if they were going make it 5v, they could have used a different connector.
It's purposely made with normal DC jack, so you can brick it... Lenovo's are just shit
@Aleksandar Z me too... thinkpads are brilliant. X201 I use, no trouble at all, despite liquid spills and many drops.
@@ДимитърАндонов-ъ7е "Lenovo's are just shit" - That's not true. The normal-sized ones (the ThinkPad series) are good, MUCH better than HP laptops for instance.
Good suggestion, it would have avoided people plugging with high voltage chargers. If you don't find that specific charger, then you can't charge
I would love to see the current market laptops. Your thoughts on them on durability, and all around build duality.
I love your work btw!
Nice to see you back! Always check input voltage ⚡⚡ 😉
thank you sorin
thanks for the heads up gotta check the specs at the back of the laptop every now and then thanks sorin
welcome back sorin ...great info for your watchers
you have a way of making repairs interesting, thank you and keep it interesting as always
It uses 5V because that is basically a tablet, not a laptop. They just use tablet parts inside a laptop case.
Glad to see you Sir.....Thanks for everything....God Bless You
Thanks for sharing your experience
frozen frozen! In fact it shows Lenovo logo just 1 second before applying 5v again!
I never saw a pointless video from you, it's always thumbs up worthy.
Thanks for the tip ! I really like your videos.
Good info and good fix
Thank you sir for ur information about that kind of laftop
Sorin i met you in 1997 i was down from Scotland with wullie in the gold datsun car i met you outside your house
its not the first time your tools have gone missing YOU SHOULD LOCK THEM UP so the others cant take them
i love ur videos bro its really helpful
I think there should be more low voltage options with everything electrical. Good to run green with solar.
Thank you very much for this information about laptop.
Can you do an update in the next video in regards to the solar panel project (maybe the conclusion) and also you said something about some games at some point. Are you still game-ing, or the Helium stuff cover all your time?
The laptop start before you touch it.
Rule number 1:
When we do hard reset on laptop ( unplug the battery) you have to wait more time to boot the laptop, because the bios reset
Big Thanks From Algeria.
It's not a laptop. @5v it's just a tablet.
i have a few 5V Laptops and i mark them next to Socket with little tag and 5V so i cant accidentally apply 19V You/they could also install a 7V Zenner diode to fuse and earth to kill the power if the wrong power is applied as sockets are very standard and accidents can happen..
Why would you plug a charger into something without checking it's voltage requirement first? That's like electronics repair 101...
Because jobs are done in a rush and you do assume that every power supply is the same. So slow down and just check power supply
One would think it would come with one of the small charging ports, making it harder to use the wrong charger in first place.
Thanks 👍 for the info I thought all laptop only use 18v and 19.5v only. That's cool 😎 thanks.
A very useful 6 minutes Sorin. I see that LEVANO have discontinued this model, on their site at least.
And this is why i request the power supply of any laptop that come for no power issues... :) btw
Lenovo would you burn the laptop using a power connector like 5.5x2.5 19v ( asus ) instead of a smaller one ... mediacom ( in Italy ) was making 5v laptops but using a power connector that not is used by any other brand.
many thanks, but what you mean there is no hard disk drive? there is no M2? so where the data stored?
good job mate.
they probably used parts from phones which are made with 5v as the main vcc. It's actually a pretty clever trick to get a laptops price very low.
The board in this laptop looks very similar to the board in a dirt cheap windows tablet I have. It also charges with 5v but from a very tiny barrel connector (jack)
I dont get how you just assume it needs a 19v charger, I know its standard but dont you get the chargers of the customer?
Welcome back
I used to work in IT support, Lenovo's laptop would break down extremely often, these were the high end laptops too. Out of 50 new Lenovo laptops, 1 or 2 out of 50 would die after a year. I would never buy a Lenovo. The HP high end laptops would last forever, forever i mean 15years+ before they started to break down. This was 10 years back so things may have changed after watching this video, I doubt it.
Thank you for the advice. However, i have a question on a different brand, HP. I have three HP laptops with the same problem and that is they cant switch on but all the voltages are present on the motherboard. The power switch is receiving the required voltage of 3.3v and the switch is responding to key press by going to 0volts when the key is pressed. I am suspecting the SIO chip. The models are HP G62, HP635 and HP CQ58. I would like to confirm of the issue before ordering the chips.
Wow that is indeed a dangerous laptop. Thanks for the info.
yea man, it's so bad for health.
we're back like never before!!!!
where do you get the leads that connect to your power supply like what you have can you show me please?
Short and sweet
Ok thanks sir
Never assume always verify and have a sand bucket nearby just in case :)
Why he is saying better with 19V 1A instead of 5V 4A. In these both case the power is about the same 20W. Why 19V1A(19W) better than 5V4A(20W)?
Because 19 v is still safe for humans, but will strain way less due to low current consumption
Hi I need a little help I have a Lenovo ideapad u310,it’s been in my wardrobe for many years as it wouldn’t switch on or show any signs of life, even if the power cable is plugged in, I’ve dismantled the laptop to see if by resetting the battery and bios battery would help but it didn’t, just nothing happens. Was wondering if you can help in any way please I’m based in the UK so was wondering how much would it cost for you to have a look at I feel like it’s just a waste really. Please let me know.
Where is the Wi-Fi card please? I’m struggling to find it
My 10 yr old nephew has Powerspeck Notebook computer i7 model 1710
It has these issues:
Gets overheat easily
Turns off randomly
Battery does not charge
A lot of applications always open
Search engine open
Uninvited Notifications
What's the best thing to do? How to diagnose first?
tackle overheating issues first, remove all heatpads heatsinks and fans clean them properly then apply new thermal grease reseat all fans and heatsinks and replacing the heat pads if any, and fingers crossed its sorted, this can cause pc to restart if they get too hot
if pc is still restarting focus on memory modules, remove them clean the gold contacts blow the dust out the memory slots try them one at a time in each slot and iif you have one slot only try another memory stick instead
70% of all computers that have no heating problems but keep restarting have faulty memory or hard drive, so yes check or replace your hardrive after you check your memory, then start detatching wifi cards cdroms card readers etc and usb ports and keyboards each time you remove something retest for restarts
battery not charging ? check your battery voltage with a multimeter
once youve waded through this and your laptop/pc is working again then you have to delete the drives partition and reinstal windows fresh, make sure you back up the bare minimum needed cos your computer is likely infected
as soon as windows is loaded instal some antivirus before you import back any files and you should be good to go
also get an adblocker and some pop up blockers for chrome or explorer and increase your memory if you have many open apps and web pages 8gb is the bare minimum needed, 16gb is best bang for buck, 32gb is for the pros
@@jasonr9157 Thanks Jason, I'll try to do that.
is there a way to fix a cpu failure on dell vostro laptop? is there a possibility it could just be a corrupt bios?
Спасибо👍
Imagine in a home FULL of devices (like mine) where kids a wife label NOTHING and there's a dozen charging cords to choose from. Using standard 5.5x2.5 or 5.5x2.1 jack is RIDICULOUS, but DRIVES SALES OF NEW DEVICES 😠.
I bought one Lenovo computer, and will never again.
Hello sir, Please I need some help!
My laptop turn off while unplugged and it will start getting hot and won't turn on till all the battery juice has gone off.
Is this laptop have a ssd slot?
haha, I saw lenovo, and was expecting a 2 hour video filled with disappointment. You have had such bad luck with the lenovos!
Nice one
This is what happens when they use cheap tablet motherboards in a laptop form factor without protection
It think it's the DC jack that's the source of all evil here. When you're presented with one you simply don't expect anything below 9 volts really.
my fusion laptop is 12 volts
It is feasible to fix such a CHEAP device? I mean, after a second issue, just replace the thing.
Ha Ha Ha Ha Soring do you know how much Bios reset we have in the Lab? 1 laptop on 5 came to the lab, its alaways happend, i liked you say its sick :-), thanks for ur video very like it
plug 19v charger and kaboom....
I need to join classes it's possible?
Great. 😍😍😍😍😍😍
Ouch, what a booby trap, ie, 5V.
Happened to me once with a Packard bell 🤦🏻♂️😂.
When it's already not turning on you can get away with it (a white lie🤷🏻♂️😂)
Let’s smoke 💨 the board 😂
Lol I had Ideapad 300s only for web and movies
Worst garbage I ever own :D
sensei
big phone with 5v
5V Laptops....WTF
That’s exactly why I don’t buy Lenovo.
🌹
This "laptop" is a junk! Actualy is a tablet or phone motherboard with a big screen. I have one named Prestige, a rubish, he died în less than 6 months...
What will more invent to foolish the customer?
😍😍❤
That's just piece of sh@t
I agree, it reminds me of a cheap Prestigio shitebook I once bought for my uncle and had to repair later. They are designed to fail the moment their warranty expires
Such a stupid device i don't even know why are they making those toys...except for money ofc...
👍😳🔥
FOR ME IS CHINA TABLET NOT LAPTOP ....
Lenovo's rubbish design
haha i burn 2 also
Hahaa, so i'm not the only one :))))
lol
@@electronicsrepairschool hi boss please can I get your contact. I got some systems that I can send to for repair
@@electronicsrepairschool It sounds like Someone needs to Investigate and Sue The People making these Laptops if putting in a different type of Charger ruins The Computer
Just look on the back, the voltage is listed there. Common sense really.
It's not common sense really, because they put typical DC jack that is used for 19 v typical for laptops. If they used USB c or microusb, it would be common sense 😉 that's just a way they sell more devices and they knew it
@@ДимитърАндонов-ъ7е I say again, Just look on the label on the back, the voltage is listed there.
@@ralgor100 it's just poor and greedy design
LENOVO = SUCKS :)
