Laptop Power Connector Plug Size

November 2nd, 2017

My good old Acer laptop started to smoke sitting on the couch yesterday evening.

Growing old, in cat years my laptop is an old gray tomcat, but with a SSD and some good memory, you can grow old rather vividly these laptop days. A mouse a day keeps the doctor away.

But it wasn’t smoking a cigar; the wire near the plug was short-circuited, probably all the bending a lifetime¬† was suddenly to much this particular evening.

I saw it starting to smoke, so I unplugged it immediately. The adapter was, like any good house-cat, lying on the newspaper. Wow, my house could end up in a fire, taking a piss.

Then I started to look for a new adapter, old laptops work fine, but old batteries are suffering from age, and I couldn’t find a good fit.

All brands seems to have a specific adapter size, so I made a table with power connector plug sizes for different laptop brands:

Brand Plug Size Volt Ampere
Acer 5.5mm x 1.7mm 19V 2.0A – 4.74A
Asus 5.5mm x 2.5mm 19V 3.42A – 4.74A
Asus Netbook 2.35mm x 0.7mm 19V 2.1A
Dell 7.4mm x 5.0mm 19.5V 3.34A – 4.5A
Fujitsu 6.3mm x 3.0mm 16V 4.7A
HP 4.8mm x 1.7mm 18.5V 3.5A
IBM / Lenovo Thinkpad 7.9mm x 5.5mm 20V 3.5A – 4.5A
Lenovo 5.5mm x 2.5mm 19V 3.42A – 4.74A
Sony 6.3mm x 3.0mm 16V 4.7A
Toshiba 5.5mm x 2.5mm 19V 3.0A – 4.74A

These are the most common ones, please let me know any mistakes or omissions.

    Hi, I have a comment about this post, where comments are already turned off:
    https://dev.webonomic.nl/how-to-disable-css-transforms-transistions-and-animations

    While this was certainly helpful, I ran into some sites where it didn’t work, e.g.
    http://www.pella.com/
    https://stephanwagner.me/only-css-loading-spinner

    And I found that I have to use *, :before, :after as the CSS selector instead of just * to override the animations that are defined using :before and :after, e.g.
    *, :before, :after {
    animation:none !important;
    }

    The CSS spinners on some pages hang my browser, so I had to find a way to get rid of all of them.
    Maybe you’d like to update the post, it seems to be a popular one.
