  • Old Dell E5400 Laptop ( Purchased in the year 2008)

    Hi, I'm unable to find the motherboard number (PPID number) or the board view for this old laptop. My laptop won't start, and when I enter the serial number on the Dell website, it says the number is invalid. The sticker on the bottom is unreadable because it has faded over time. Unfortunately, I'm unable to start the laptop to use the power cell or explore other options.I needed the CMOS Cell & it also seems the Laptop will not start now because of the power switch issue, which is yet to be detected.

  • Need help id'ing chip on a Dell g15 5515

    Hello all,
    I have this dell g15 Ryzen Edition 5515. Board GDL56 LA-K453p. It had liquid damage when i bought it. Cleaned it up really well and then used thermal camera to see what got hot.
    Found the power pdw1 and pdw2 under the graphics card were getting hot. Pdw2 was hottest, i had a similiar chip on another board so i put it on this board.
    The other chip is now hot as well, which it was to begin with.
    Thats the problem as i dont know what to call it, like is it a mosfat? or what?
    I will attach a picture of both the boardlabel and of the area with the chips....

  • Lenovo M725s AMD 2400G upgradable to run Windows 11?

    I’ve got this Lenovo M725s with an AMD Ryzen 2400G here on the bench. Supposedly it’s only good for win 10. Win 11 doesn’t support the Ryzen 2400G. However Win 11 does support the Ryzen 2600?
    there are a lot of CPUs that fit the AM4 socket, but this mother board based on a 450 series does not support the Ryzen 3000series or up. I think due to bios limitations from Lenovo.
    Now here things get vague: In one way Lenovo sez the M725s’s are not upgradable to run win 11. Other hand Win 11 supports the AMD 2600 and the 2700.

    Anyone got an M725s with a Ryzen 2600...

  • Recapping a Denon AVR X6400h SMPS

    (TLDR: It was capacitor C6519 [Koshin KZH 50V22uF] and C6515 [Koshin KZH 25V47uF] on the power supply. I have questions at the end)
    Disclaimer: I'm an amateur hobbyist and will get things wrong.
    Always use caution when working around mains power and high voltage capacitors!

    Hey guys, I'm repairing a Denon AVR X6400h for my brother. It quit powering on after a power outage. It acted like this last time there was an outage, but after letting it sit overnight it started working again for a few years. This time letting it sit did not bring it back.
    SYMPTOMS:
    -No display...
