    Laptop Blown fuse replacement

    Hello guys.

    I have a sony Vaio that has a backlight issue , i found a fuse ( polyswitch 1A / 32V ) on the motherboard side being blown , so i used a wire to jumper to see if it would work and it did.
    So my question now :

    Do i need exact replacement for this fuse or can i use another normal fuse or even resistor ( low ohms like 5 or something) ?

    LOoking forward to your answers. Cheerz

    for me i always use the specified value to protect the unit...my opinion..

        Ye i'll get the right value but what about using a normal fuse insteaf of polyswitch

          A polyswitch is a resettable fuse which means once blown it will take a few days to reset if the problem that caused this is fixed and a normal fuse just blows and i have to replace it again.

          So if i'm missing something why i shouldn't use a normal fuse or even a current sensing resistor please tell me

            Argon SA1 audio amplifier power-supply - fuse blown after fixing the short?
            by Babbar
            I found a project in the electronics trash yesterday. A nice Argon SA1 audio amp with some electrical issue. Took it apart and saw that the 4A250V fuse was blown so started lifting components to find the short. Eventually got to two MOSFETs (model FTA14N50C) that are shorted and when i took them out the short was gone.

            Now i didn't have any replacements of the same model of course but i found a couple with pretty similar spec i thought (K10A60D & K12A50D) and put them in. Also replaced the blown fuse with a 3.5A250V one. Checked another time for short circuit and plugged it in....

            Lenovo Thinkpad E15 Gen 2 NM-D011 - No display ? External , yes!
            by Acnologia
            Here is a pretty crazy one.

            Step 1.
            Laptop was brought to me as dead not working. Removed everything , cleared everything.
            Step 2.

            Some liquid damage close to the Type - C connector, and the connector even though it was cleaned wasn't charging the battery . Removed the Type-C port, and replaced it. Now the laptop turns on and charges battery. Shows external screen , not internal.
            Step 3.

            Took out the screen and checked it to a secondary Gen 2 i have, screen works like a charm.
            Step 4.

            Lets ,dive into the board. I see the edp cable on the...

            Carver CM-1090 - Power relay clicking on & off, then fuse blown after 20-30 seconds of power cycling.
            by beetle1303
            I gotten a Carver CM-1090 amplifier from a friend who has kept it in storage for decades. Opened it up, thick layer of dust cumulated everywhere. Vacuumed it semi-cleaned, and blown off as much as possible the remaining dust. This is a 220V version.

            On initial powered up with nothing connected - it works with all the lights and button indicator lit up as pressed, etc. I then powered off, connected a CD player into the CD RCA input and powered it on. It seemed to work for a short while and when I turned the volume up and down to see the the VUs works, the power started to clicked off...
