this laptop was damaged by a roof leak at the repair shop that it was at while waiting for a replacement cpu fan. It was given to me to try to save the motherboard which wouldn't power up anymore. The only issue now is that an sot23 marked R1 is missing one of it's three legs. I cannot find schematics for this model but I found a mosfet that has the same label but i'm not sure if it's an actual match. CJ3401 is the one that I found but I have no clue about the true identity of the damaged one.

Post a pic of the SOT23 in question. Highlight the top markings with IPA and then take a good pic. -
can't get the camera to focus on tiny objects but it's an sot23 with R1 as the top marking. CJ3401 is an sot23 also with R1 as the top marking but not sure if it's a matchComment

Maybe you can still probe the broken leg tip on the SOT-23 body? Consider to measure it in resistance mode and compare it to the CJ3401 measurements to confirm. For this, you must source the CJ3401.Comment

I have this laptop that does boot but it's on an older BIOS that has issues with Secure Boot, and I cannot use the normal Razer BIOS updater because for some reason the serial number is missing / got deleted somehow (Common issue on this model, from what I've read). I got a dump of the BIOS chip (or at least what I think is the BIOS chip), and its 16MB in size - the files from the Razer BIOS update are 8MB. (There's two 8MB files, am I supposed to combine these somehow? Or combine with an Intel ME firmware? I have no idea).
So, I'm looking for a BIOS dump for this machine - a 16MB one.... -
Razer blade 2022, 14" PI480, Ryzen 6900HX, 16gb ram
I picked up a Razer blade 14" (2022) from a friend who said it "overheated" and he replaced one of the fans. He gave up on it as windows wouldn't work/re-install. He gave it to me, and i've been working on getting linux on it. Installing Mint i was able to get about 1/4 through the installer before it froze. Now i can't even get the installer to boot. I am met with a kernel panic.... sometimes. Sometimes it just hangs on the boot sequence.
I've run memtest quite a few times, and more often then not... -
Back Story
I just recently purchased a RZ09-01652 Razer Blade 14 Touch v4(2016) as a project. I suspect the original motherboard had overheated and caused board damage to the vrm's for the CPU and GPU as now that motherboard works however will lockup on you often due to hardware clock issues.
So after some research and looking at options for replacement motherboards I got a replacement RZ09-01952 razer blade 14 motherboard which has the 1060 vs the 970m that was in my original motherboard. I have contacted the seller about the motherboard being bad however I doubt they will be... -
Hi All,
I'm trying to repair a PCB that has some surface mount SOT23 devices that apear to be transistors but testing them on the board are giving confusing results.
Its named FS45 but I can't find a datasheet that seems correct.
The device is used in 10 places on the PCB. In 4 cases they appear to be controling triacs and the attached picture it shows it connected to a BT136 triac with the FS45 connected to the gate leg of the BT136.
Can anyone identify the device and suggest an alternative?
Many thanks.
PS: I have... -
Hi everyone,
Looking for schematic for RAZER BLADE 15 RZ09-0369. Looks like the motherboard is Razer DA560. TIA05-12-2024, 10:25 PM
