This is a creative way to repair the hinge issue. Ive done many of these when the LCD cover is not available or customer is on a budget. Only thing I would recommend is dont use the entire flat bar. You can just use a square cutout where the damaged hinge is. great content!

Hello! I have an e7440 that doesn't power on. it keeps the power light on for about 10 seconds, then the battery light flashes and goes off. I've tried new cmos batt, reflash bios chips, to no avail. Is there any known cause of this?

hi HP PROBOOK 430 G6 DA0X8IMB8E0 Rev E (!) MODÈLE X8I bios thanks

Thanks for the knowledge sir

Thank teacher

(5:55 exactly) Winbond 25Q128BVSIG. If that motherboard uses a 10th or 11th generation Intel CPU, I would copy the BIOS files to a new (blank) SPIFlash memory and install it to check if the new copy works. I would apply this same procedure if you use an eeprom for the data that "communicates" with the Super I-O. Excellent repair without a diagram but with the data sheets and the experience acquired to date. I loved it. A sincere congratulations. All the best. PS: If you make a video (with your way of explaining things) when there is time or opportunity, many of us would watch it (it would be a reference to consult😊).

I am interested if the replacement chip will come with the correct firmware or you will have to use the Texas Instruments Application Customisation Tool to program the new chip via the SPI interface? Will there be a part 2 on the video

Great Video! Maybe it could have been a frozen EC chip? When you took out the board to photograph you disconnected the RTC and main battery so the BIOS got reset so it could have resolved the issue at this point and been nothing to do with the DIMM module? If the memory wasn't detected in the slot due to dust or bad seating I think a HP laptop would be able to detect this and give an error code in the form of a blinking sequence on the caps lock key. You could remove the module and try and power on without it and see if you get a light pattern to prove this point.

Maybe rust, carbon build up on the pins or the RAM or both. Changing the ram fixes it then maybe the previous ram was faulty or incompatible.

Incompatible SODIMM? Was it single or double density RAM?

Amazing job! Thank you!

Hi. Pretty good idea but looks like a lot of work... I haven't had to deal with this myself but would suggest trying screw rivets. They would just leave a nice blank screw head on the outside. Enjoy your channel. Paul from Canada

do u think u could repair mine?

Very good videos and tutorials. I appreciate the work involved in graphically blending real images with cartoons. I am a subscriber and look forward to more videos.

All the measurements on the ceramic capacitors and even better aided by the thermal camera itself indicate that the TPS65988 IC is damaged (at least I am totally convinced of it myself). Another way to expose it, without needing to remove the IC yet, if I remove (desolder) the three ceramic capacitors one by one and measuring continuity between the pad removed from the pins 9, 25 and 46 with respect to chassis ground,; With only one of those pins (any of the three) indicating a short circuit, I would order replacing that IC with a functional one (new or used), without any discussion, clarifying to the technician that I do not want to find any solder bridge. between the attached (neighboring) pins when I personally examined it under the microscope. Excellent preliminary (initial) work, please replace that IC and let's see what happens (it's just the first battle in this fight)... if necessary we should continue the troubleshooting. All the best.

I love your vidéos, always very useful, a very clever approach !

Thank teacher

Ah, so we are both going to battle, armed with a lot of very hot air, flux, and determination! I do not look forward to anything related to USB-C, but it is inevitable.

Hi what software do you use to put the markings on the pins of components please.

Hi, Please note that I tried the laptop initially with a universal charger (at the start of the video), and then borrowed a legitimate Dell charger from my friend which I used for the rest of the video. This is my first experience of the USB C and PD Controller power setup, so I will be hoping to build on this in the next few months. Please post any comments or suggestions in the comments section below. And I wish you all a very happy new year!

I find this very wrong cause it adds weight to the laptop.In my opinion the best way would be to put a a scew through the brass inserts and with a metal washer to tight the hinge inside the laptop.

I checked that pin # 4 and only got 1.3 Vdc. Tried grounding, but nothing happened. Checked battery output, which read 8.03 Vdc so battery is okay. Am stuck now.

Thank you for all videos and I wish You a Merry Christmas!!!

Sometimes you have to do that kind of work. To do it quickly: a) Brushed Stainless Steel Sheet Metal Plate (Very Cheap) b) rotary tool (dremel) - the device is NOT cheap due to its high-speed motor - but the cutting discs and other pieces that make up the assembly ARE. c) Rectangular silicone rubber sealing strip (aesthetic presentation, that is, it covers the metal plate to look nice or pretty; it is also very cheap) Thank you very much for sharing. All the best.

How were you able to fix it at last pls? I'm experiencing this same issue on my HP 250 G8 laptop.

It's not a good idea

planned obsoleteness

Hi Everybody, the laptop I had for my repair this week turned out to be just a BIOS re-program, so it was not worth making a video on. So, this afforded me the opportunity to put forward my proposed solution for the hinge problem that we see on many of the modern Dell laptops. I've been thinking about this for a while, and this is the most practical and least expensive solution I can come up with! The items used to carry out the work in this video are: 6 x M3 Screws With Washers Flat Steel Bar 1000mm x 16mm x 2mm 2.5mm Drill Bit 3mm Tap File Grey Spray Paint Please feel free put in the comments below your own opinions / criticisms / optimizations on my solution.

Great approach. I repair in a Repair Cafe - max 3 hour stint, before you are thrown out. Also had failures with hot glue. Superglue did not dry fast enough either. My next attempt when I get one will be super glue and backing powder next. Just do not have the time and machinery to do this in a repair cafe, but other than buying a new lid, it is the best solution (in my eyes) Do loosen the hinge slightly.

Story of my LIFE!

Hello. a) If you remove (desoldering) that small ceramic capacitor and then measure Pin 9 on the Super I/0 with respect to ground, that is, place the red tip on pin 9 and the black one to a known ground (screw hole and/or the metal chassis of a USB port): Does it no longer indicate a short circuit? b) On the PU801 (6 pin smd IC) with the multimeter in diode test: Black meter tip to pin 2 and red tip to pins 4, 5, 6, 1 and 3 (one by one) No reading indicates short circuit? c) Are the 5V always present? To run the heat sink fans that protect the chipset. Another way to say it, although the chipset shows an image that it is running hot, the camera temperature I saw was 15 Celsius because the current injected was 100 mA. If, upon increasing the current to 500 mA, I had seen a temperature of 55 Celsius or higher, I would say that the probability that the chipset itself was damaged is very high. In other words, I suspect the Super I/O IC that, since it does not have 1.8V on pin 9, it does not send the order to activate the chipset. Thanks for sharing. All the best.

❤🎉 excellent work.

hI THANK YOU cOULD YOU SHARE TO US repair controller e bike

RIP

Great video again. Thank you!

sadness. i was thinking bios because of the 1.8 but thermal showed it. better luck next time.

Watching the Thermal Camera, the chip burning seems to be the small chip near the Battery connector... and seems to be the Bios Chip.. Not Chipset.. but don't have the schematics... 🤔

More spare parts! Last week I paid $140 for two 17-inch Dell Inspiron laptops. One had broken hinge screw mounts, and the other one had a dead PCH on the motherboard, so I swapped motherboards and added the extra parts to my stash.

can't win 'em all sadly

Excellent

Thermal camera, finally 😊

thank teacher

First thing i'm testing on a faulty board, and the easily.. is the cmos battery.. but was not the fault here ;)

Excellent work ❤🎉

Hi ! Did you simply remove the bad capacitor or replaced it ?

A very clever troubleshooting ! but too much damage on this board, anyway very informative...

very clever work ! A thermal camera is a must have !

Gosh, every repair is a bad cap. Why do I always get dead PCH and other cr@ap?
