HP 15-cs3055wm - DAG7BLMB8DQ REV:D - Missing Components - Fan Error
Hello,
I have an HP laptop here (model and board model in title) that powers on with an error message about the fan not working properly and needs to shutdown. The thing is, the fan is spinning just fine. I disregarded the message and continued to boot into Windows and loaded up OCCT to look at temperatures and the OCCT was reporting that the CPU was very hot (98C) and climbing, so I shutdown the computer, did a CMOS reset and checked then thermal paste and heatsink for dust build-up. Paste looked good, but I cleaned it off and applied fresh paste anyway and blew out the fan from...

Just wanted to come back and update this. I purchased the following switch from eBay: [url]https://www.ebay.com/itm/275901936717[/url] and it worked. I did have to modify the pins a bit to get it to fit, but it works. Just updated for anyone else who might read this in the future. Thanks!https://Just wanted to come back and...uture.

I considered that, but I compared the two BIOS .bins in a HEX editor, and they are vastly different....

MacBook Air 2337 - Right I/O Board Audio IC - Alternative Replacement?
Hello,
I'm working on a MacBook Air A2337 that had liquid damage on the right I/O board. I ultrasonic cleaned the board and it all functions except the computer has no audio. I tried reballing the audio IC which is [B]TAS5770AC0[/B], but that did not restore audio. I could just replace the entire board, but I wanted to see if replacing the audio IC would fix it first. Mouser has a similar audio IC in stock which is [B]TAS5770LC0YFFR, [/B]but I wasn't sure if it is compatible. I was just wondering if anyone knew if I could use the one from mouser as an acceptable replacement or if...

Dell | LA-K034P REV 1.0 | Possible Shorted CPU?
Hello. I think I may have a problem with the CPU, but I was hoping someone could look at what I have done here and confirm so I don't waste more time on this one.

Thermal camera showed MOSFET PQZ1 getting really hot and inductor PLZ01 was reading short on both sides.
Replaced PQZ1 with new B03N03R MOSFET.
Laptop now charges and powers on, but only for about 10 seconds before it shuts down abruptly. The fan also runs high during the...

NEC TurboExpress On/Off Power Switch Replacement Help
Hello,
I've been working on a NEC TurboExpress and I accidentally got the plastic inside the power ON/OFF switch too hot while doing other repairs and melted it. At first, it would still power on when sliding the switch, but you had to really press inward while sliding to get it to work.
I removed the switch component and tried to gently melt the plastic back so it would work more reliably and all I managed to do was make it worse.
I need to find a replacement On/OFF switch for this, but having some trouble figuring out which kind of switch I need....

Re: Latitude E6530 - Trouble Extracting BIOS Image From EXE
Ok thank you. I briefly started reading some guides about how to do that, but I've never had to do this before and right now, it all seems a bit over my head. I really appreciate your help and please, take your time with whatever you're working on now. I'll just watch this thread for your reply.
Thank you again....

Re: Latitude E6530 - Trouble Extracting BIOS Image From EXE
Hi. Thanks for the reply. Unfortunately, those files you extracted and zipped for me are the same files I was eventually able to get myself. I have no idea what to do with them to get a 4MB and 8MB file.
I really appreciate you helping me though. Thank you!...

Latitude E6530 - Trouble Extracting BIOS Image From EXE
Hi folks,
I'm having a hard time extracting this Dell BIOS. I have a Dell Latitude E6530 that has BIOS corruption and I need to reflash with CH341A programmer. I have already taken dumps of both the 4MB and 8MB chips on the motherboard.
Service tag number for this model is: "JYDWYW1".

Need Help Identifying Capacitor On Kar-Tech Versa Remote
Hello,
I have sort of a weird one here. This is the circuit board for a Kar-Tech VERSA remote. It's a wireless transmitter for crane and other heavy equipment.
One of the capacitors have blown and I need help finding a replacement. The capacitors are 11.4mm x 6.6mm in size and the only imprint on them is "200mΩF", which I am assuming means 200 microfarads. There is no other markings on them. I have tried doing some searching on digikey and mouser, but I can't seem to find anything like this on there or I am inputting the wrong search parameters....

Re: Lenovo Legion T5-26AMR5 Desktop - Corrupt BIOS
Also, are you sure it's a zener diode?
You may take a look at this one: [url]https://www.digikey.com/en/products/detail/torex-semiconductor-ltd/XC6210B332MR-G/2138119[/url]
I found that using: [url]https://smd.yooneed.one/[/url] - which has helped me in the past identify components. Pretty cool website. According to it, the digikey link I posted above could be your component, which is a voltage regulator. Use the [URL="https://www.torexsemi.com/file/xc6210/XC6210.pdf"]datasheet...

Re: Lenovo Legion T5-26AMR5 Desktop - Corrupt BIOS
Unfortunately, no. I tried flashing the BIOS multiple times with multiple different versions released by Lenovo for that board and none of them worked. I even tried replacing the BIOS chip itself and flashing it and that didn't help either.
Due to time constraints with my customer, I had little choice but to simply offer a motherboard replacement. I offered them a replacement with the original motherboard which was about $170 if I remember plus labor or to replace with another B550 chipset board that...

Re: Lenovo Legion T5-26AMR5 Desktop - Corrupt BIOS
Hi there. Thank you for taking some time to try and help me, but unfortunately the BIOS you provided makes the computer behave the same way. It does power on, all lights and fans spin, but nothing ever appears on screen....

Lenovo Legion T5-26AMR5 Desktop - Corrupt BIOS
Hello there.
I am working on a Lenovo Legion T5-26AMR5 desktop that currently has a corrupt BIOS and I have been unsuccessful thus far in trying to fix it myself.
History:
1. This computer came to me initially with an error message that said "BiInitializeLibrary failed 0xc0000001" or "0135 fan error". It would always be one of the two errors. It should be noted that when it produced the fan error, there was no physical problem with the fans. They were all spinning just fine.
I searched for this error online and discovered...
