Laptop Does Not Start, Some SMD Is Blown, What Is It? – An affordable mid range laptop sold by Acer in mid 2015. This laptop comes with a Nvidia 940m graphics card, Intel i5-5200U CPU, and a 1080p display.
Question: Hej, Ive got a laptop Acer aspire e5-573g that is not starting up. Looks like it is not getting any power at all. On one side of a motherboard on the other side of the DC connector there is an SMD blown that I cannot recognize. Check pictures. Can anyone tell me what is this piece and where can I buy it? Appreciate your help! Regards! !!!UPDATE!!! I have removed the blown part as shown in the picture her: Doesnt the marking underneath the blown piece indicate that it is a kind of a diode? !!! UPDATE 2 !!! I have checked the continuity readings from the plus pad and adjacent ends of capacitors. Readings are fine, I mean no continuity on opposite side of capacitor. I tried to check for splashes or whiskers of solder on the components around without any obvious luck. Check some images: I believe the latter image shows the PU11 IC and resistors PR127, PR128, PR229 located around it. There no seen defects except one black leg on IC close to the C letter as seen on the following images: Could this indicate that IC has shorted? Or is it just meaningless debris? The leg looks kind of shorter than the rest as if it was burnt. UPDATE 3 (and hopefully the last): Ok.. the SMD part purchased was 1N4148WS-7-F – Switching Diode SOD-323 75 V 300 mA, Diodes Incorporated with the datasheet located her: https://www.elfadistrelec.dk/Web/Downloa… The piece is much smaller than original part on the motherboard, picture follows for comparison. The piece was soldered as shown in the image and the laptop STARTED LIKE A CHARM! Huge thanks to @oldturkey03 and @pleriche

What to do with a dead hard drive?
I have actually discovered that the platter of an all new hard disk drive isn’t 100% remarkable when it comes out of producers. This is due to the fact that the platter is really specific and has a high need in the production atmosphere. Therefore, also a speck of dirt or a small accident can bring about a couple of to numerous negative markets.
Laptop Does Not Start, Some SMD Is Blown, What Is It? As a result, if a hard disk drive is dead and also it’s not triggered by human variables (such as physical scrape and also sensible damages throughout using), individuals could decide to send out their hard disk back to makes for upkeep as lengthy as it does not go beyond the guarantee duration. Yet previously individuals do this, please keep in mind to back-up hard disk information if it is feasible.
If the dead hard disk is an outside one, the healing & repair would certainly be a lot easier:
Step two: replace the damaged part.
If the laptop own surpasses the service warranty duration, you could aim to eliminate the harmed component and also change it with a brand-new one. Under such situations, you require a screwdriver, such as Phillips screwdriver and also hex screwdriver for taking off the cover so about change the damaged element.
- Eliminate the screws with the screwdriver.
- Take the cover off thoroughly.
- Situate the element in the laptop and also take it out.
- Place a brand-new one right into it and returned the screws.
