  1. Welcome, what model of Dell laptop do you own?

  2. Jeremy W.

    Is there any soldering required in the Dell Inspiron 1545 DC Power Jack / Usb IO Circuit Board Removal and Installation? How does the board connect to the Mother Board? Is it a ribbon cable or another means?

    • The DC board presses onto a socket on the motherboard and is screwed down to secure it. If you are replacing the complete DC board then soldering is not required.

  3. Kerrie

    Thanks for this guide. Just sorted my son’s machine.

  4. Tom Cable

    Fabulous instructions to replace. Extremely poor design by Dell. This board should be
    replaceable short of removing the motherboard.

    • Kelly B

      I agree. I think they make them to self destruct so you have to purchase their extended warranty. I personally will never buy another Dell. Ever.

  5. Tom Cable

    I just fix them. working on a inspiron 1545 presently.

  6. Matt

    Thanks for this, just followed your instructions in order to get my wife’s laptop working again. Just one thing – I skipped removing the wireless pci card, I don’t think it’s necessary. Everything else was spot on

  7. kaz

    how much does a genuine replacement cost? My charger port is broken but the only ones i can find are on ebay for about 10 to 15 quid. are these original? How can i tell and where do i find part number as well?
