Technician: You have to replace the fuse! That's not a real fuse, and the real fuse does not looks like that! Sorin: No, this is proper calibrated fuse. We will go by the book. This is how the fuse looks like •~•

When you started to put in that wire instead of a fuse, I was horrified - until you made it into a proper 'S' shape, THEN I knew it was a proper calibrated fuse. can't believe!

26:42 info for beginners: if you connect two capacitors like on the video (in series), then you double the voltage tolerance (the capacitors must be the same) but you lower the capacity. And if you connect them side by side (in parallel), then you double the capacity but the voltage stays the same if the capacitors are the same - if not, then the voltage drops to the weaker one. Keep in mind that these smd capacitors don't have polarity (+/-), so here the orientation is not important.

@SerenoOunce Жыл бұрын

To have ~the same capacitance w/ necessary V you'd need *4* caps in both parallel and series, cramming in the largest package size you can fit. Or bodging in a ceramic disk type would be another option if no SMD available.

@basshuntet6128 Жыл бұрын

is it the same for resistor?

@Radek__ Жыл бұрын

@@basshuntet6128 almost the same - the different is that you don't boder about the resistors voltage but about the current tolerance (power dissipation) which that resitors must handle. ... if you connect two resistors 5ohm in series you have 5+5=10ohm. if those two resistors can handle 3wats, then both in series also handle 3wats. If one is 1wat, secnond is 3wats, then if you conetct them in series, the tolerance dorps to the weakest one = 1wat. ... if you connect two resitors 5ohm in pararell then you lower the resistance = it will be 2,5ohm (for more than two resistors you have to use a matematic calculations) and the Power Dissipation (current tolerance) will be greather. If the resistors have the same power disspiation 1wats per each, then you will get 1+1 =2wats.

20:18 Sorin is going to replace shorted capacitor! LOL 😯 😍 btw: He didn't tell you, but that capacitor is important also, to prevent backlight flickering. If you don't replace it, then the light will pulsate/flicker and your eyes will be tired quickly 😵

One of the laptops i repaired about a year ago, has a cartrige fuse glued to the case soldered with wires to the motherboard. I was scared to leave it without the fuse but i needed the laptop up as soon as possible. Not sure why I thought that was a better idea than just shorting it with a thin wire but to my knowledge, the laptop is still in use.

I had an old model of Philips brand USB stick that didn't work (2 Gb). checking under the microscope I noticed that an inductor on the data line had desoldered. I didn't know where to find the same one, so I rimember that "an inductor is a wire" and tried inserting 2 "proper calibrated wires" and it worked. I was very happy and it's all thanks to you. the best teacher in the world

You can buy a selection box of new different value and voltage caps so you will always have some brand new ones when needed. I know from experience it is not easy to keep a stock of everything you may possibly need in the future but it is easy to keep the most common ones. Having the correct value replacement fuses is also very handy 73s Sorin

there's one thing i've understand that sometimes if you wanna diagnose some faults and try to use exact information from the book (Theory) you'll not do the job coz at the end if you can't find the exact part you leave the laptop unfixed, or ending up charging customers more for the thing that could have been fixed. sometime To people like me when it comes to theory am dumb and a slow leaner but when it comes to practical I easily catch up. However, theory its needed 100%

The laptop is nicer because it's a Thinkpad series. You know, former IBM ThinkPads. They were always higher quality and even now with Lenovo they are nicer, better built and more durable.

@carlosgarciaoropeza5480 Жыл бұрын

@ West Senkovec: Yes West. Totally agree: "Lenovo's route (trajectory) as a company was well planned. Leaving politics aside, he moved his headquarters to Hong Kong (first right decision) and bought IBM (second reason for his success)… we are living what followed, if them does not cross the limits, that is, without making the mistake of Huawei"… Another way of saying it, "it has everything to compete in the big leagues and both the apple giant and the two Korean colossi know it" (excerpt from an article in an American business magazine). PS: I liked the Lenovo Thinkpad even though only one has arrived for service but I filmed the entire disassembly with a portable camcorder and made a lot of notes in my blog. I am more familiar with other manufacturers. All the best.

if you series a capacitor, you need to paralled a resistor on each capacitors in the series . This is to ensure the voltage drop across capacitors are the same.

@jozsiolah1435 Жыл бұрын

When a backlight is too low, usually 386 and 486, you can find a component to make it stronger, that is the fuse. In new laptops, when you buy a new battery, the backlight will become stronger. For older batteries, if you refresh it in bios, the backlight will switch to maximum. It is dangerous to refresh old batteries in bios, it may not charge again. The best way, is to start the bios for time limits, instead of full discharging. After a while, old battery may accept full discharge in bios.

So the fuse can blow if you don't disable the battery or remove them before disconnecting the display cable. This is a common issue when you insert the cable slightly angled and it shorts it

You're a proper wind up merchant with the fuses and capacitor, but I'm not going to bite, this time. The worst that can happen in this case is another component inline with the fuse will burn up, but no major risk as it should be current limited. LOL. 😀 Great fix, I like it when no components have to be bought.
