    Hi, My charging port on my 1545 is loose. Do I need to replace the motherboard as above or the small side motherboard (a separate part) that contains the charging port?

  • nilo

    How do I identify my DELL 1545 motherboard model? or are they all the same?

    • http://www.parts-people.com Roscoe

      If you go to the Device manager you can look at the display drivers. The motherboard you need will be dependent on whether you have the Intel or Nvidia video chip set. If you can’t turn on the laptop then you will need to remove the motherboard and get the part number off of it. Unfortunately the label with the part number is located next to the audio ports so the motherboard would have to be removed.

  • Allan Gledhill

    Very helpful guide, thank you! I spilled wine on my 1545 and didn’t turn it off quick enough. Taken out the motherboard and cleaned with electrical contact cleaner. Won’t power on at all, no lights or sounds. Not very great at computers but having a go thanks to your guide. Do you think the motherboard is damaged as it won’t start at all? If I replace the motherboard, do you know where I can get a guide to update the bios and service tags as I am unsure how to do this? I know how to enter bios, do I just look for the motherboard no and change it? Thanks in advance,
    Allan Gledhill

    • http://www.parts-people.com Roscoe

      There is a good chance the motherboard is damaged but with spills it’s really hard to say. With no lights, sounds, or power then the motherboard is a good start. Updating the BIOs can be done at support.dell.com . It’s pretty simple, like downloading drivers. To change the Service Tag you will need a technicians disc, unfortunately you will probably have to take it to a repair shop that has the disc. Although, the service tag will not effect the performance of the laptop.

    I have a Dell 1545 that I purchased just less than 2 years ago that will no longer boot. The fan spins for a couple seconds and then stops, the laptop screen stays completely black (no backlight at all), the hard drive doesnt even start to spin and the powerlight stays on.

    So far I have removed/swapped the RAM, tested the hard drive on another computer (it worked), removed the keyboard and checked all the connections which seemed fine and tried to power it up with just the AC power / no battery but so far nothing changes the results. If I start it with NO ram it beeps but nothing else. I tried to re-seat the CPU but it seemed fine and didn’t change anything. Tried starting it with an external monitor connected – still nothing.

    Has anyone seen this before? Do you think its a motherboard or could it be something else?

    Thanks!

    • http://www.parts-people.com Roscoe

      Is the laptop giving you any light codes? do the caps lock, scroll lock, or num lock lights flash or stay solid? I have seen the video chip fail on the 1545 and cause the same issue. Where there any other symptoms before this happened?

      • Adam

        THANK YOU! see below, i replaced the board and it worked again :)

  • Adam

    THANK YOU! This video was a huge help to me. Last night I replaced the motherboard on my Dell 1545 by following this guide.

    After not using it for about 6 months, I tried turning on my Dell Inspiron 1545. I plugged in the charger and turned it on, but nothing happened except for the light at the front blinking four times amber and once white. After a couple minutes, the light turned solid white, but nothing else happened when i pressed the power button. After an hour, I returned to see that there was no light at all when the charger was plugged in. The only thing I could perceive was this faint high pitched noise that was coming from the laptop (which I found out was from the motherboard after taking it apart). It would only last about 5 seconds after pressing the power button and would only happen if the battery was in. I tried taking it apart multiple times but everything looks ok. I even tried using other batteries (not made for this laptop though) and would get the same faint high pitched noise but nothing else.It just won’t turn on. Do you know what’s wrong with it?

      It’s hard to say without having the laptop to look at. In a situation like this it’s probably best to take it somewhere to get diagnosed.

  • joylove

    Hi there, thanks for this DIY, I’ve found it most useful working on a 1545.

    I wonder if you can shed any light. The problem is the laptop won’t charge or boot (flat battery). Assuming it was a knackered connector I’ve dismantled and replaced with a Genuine Foxconn hexagon part the charging socket, still no activity at all from the charge LEDs or laptop.

    Should I be able to measure a voltage on the pin of the charger? I know some laptops have an ID resistor in the charge circuits to activate the power brick.

    When the jack is in the socket I can’t measure a voltage on the supply diodes either.

    Thanks

    • http://www.parts-people.com Roscoe

      Does the laptop turn on with the adapter? It could be a bad DC jack but it’s really hard to say without being able to see the laptop. I would suggest taking it somewhere to get diagnosed.

  • Ron

    After a spill, there were no lights or other signs of life. Used your guide to replace mother board and now it acts like it’s booting up, but the screen stays dark. Can you help me figure out where I went wrong?
    Thanks

    • http://www.parts-people.com Roscoe

      Unfortunately after spills there could be a number of things that could contribute to this problem. It would be best for you to take the laptop somewhere so it can be diagnosed otherwise you would be trading out parts hoping to find the problem.

  • simona

    hello..i started to watch and follow you quide..got to the point when i cnt lift the top to get to the motherboard as there looks like one point beside keyboard port is welded and cnt lift it..is it only my laptop or what?
    can you help me somehow..iam trying to replace dc jack. thanks

    • http://www.parts-people.com Roscoe

      I would double check all of the screw locations, you probably missed one. The Palm rest is clipped onto the base but if it doesn’t unsnap then you probably missed a screw. I have personally never seen a 1545 that was welded down.

    My mom bought a Dell 1545 laptop for my nieces and nephews about 2 years ago and all of a sudden it stopped working. We were told the motherboard needs to be changed. Basically, we took the battery out and tried using it plugged in and sometimes it works and sometimes it doesn’t. There’s no consistency in it. Of course, this happened after our warranty ended and the laptop is still so new. If the motherboard and the battery needs to be replaced, do you think it’s worth it to attempt to fix on our own? Or are we better off buying a new laptop? Looks like a fun project to undergo, using your tutorial videos and I like doing that kind of stuff, but I’m not sure if its worth it financially.

    Thanks!

    • http://www.parts-people.com Roscoe Dyer

      I would suggest having the problem diagnosed. The cost of the repair will decide if it’s worth fixing or not. I have seen motherboard ($150) problems and DC jack ($80) problems with the 1545, that would be the deciding factor for me.

      • Nicole

        I ordered a motherboard from your website and just installed it into the laptop. It went smoothly. When I turn it on, I get the beep code 2-2-2. No picture on the screen. The power light at the front of the laptop stays lit. Any advice on what to do next?
        Thanks!

        • http://www.parts-people.com Roscoe Dyer

          I would Make sure to check all of the connections and re-seat the memory. Error codes can be a lot of things, but usually after changing a motherboard, it’s a bad connection somewhere.

  • sam

    now i know i am going to sound like an idiot. but i had some problems with the touch pad, after trying everything software wise, i convinced myself it was a hardware problem. and that the oad needed a wipe down under neath. yes, i know know you cant do this. however. ive lost the plastic bits thwt i have no idea of what are called, that fitted into where the ribbon for the track oad and the power cable go, they are little plastic bits. can i get a replacement anywhere? any ideas? i also now realise that the touch oad may not work. i will replace this.

  • sam

    sorry, on the motherboard, there are connections, the black plastic that keeps the ribbon in place, can i get these anywhere?

    • http://www.parts-people.com Roscoe Dyer

      I haven’t seen the plastic pieces sold separately. You might be able to find a “Bad” motherboard on Ebay that you an strip them from, otherwise you would have to replace the motherboard.
