    Hey!
    I have this laptop which is past it's sell by date and the screen is broken too. So, I decided to hook it up to the TV and use it as a desktop TV.
    Problem is, aswell as the screen being broken - the power cable is too. The laptop uses (according to the transformer brick) 14v. But, after some Googling I found most of this power is used by the battery. So...
    - Can I power up my 14v laptop, without the battery on a 12v power supply?
    Hope you can help....

    You'll probably find that works ok. More important is the current consumed. You should look at the power consumption of your laptop (in amps) and make sure the power supply is at least that or it will run hot and if seriously underpowered burn out.

    Thanks! I'll try this and keep an eye on it. I'll monitor the temperature aswell. Thanks!
