New Power Adapter

I have a Dell Latitude E5510 laptop for work and I am thinking about getting another power adapter to keep at home and leave one in office.

My question is the one that came with the laptop is 65W so would the 90W work?

90W will cause no problem: The computer only uses the power that it needs.

Just a heads up about the power brick. I'm using an Antec NP90 at school and the bios does not allow the E6410 to go above 1.1GHz, which is kind of annoying. Not sure if there's a way to get around different charger limitations short of hacking the bios.

 

The centre pin of the power connector allows the BIOS to interrogate a chip in the PSU which gives the power rating. If this chip is not present then the BIOS assumes that the PSU has insufficient power to let the CPU run at full speed.

There is a work-around for this problem: Use RMClock or Throttlestop to override the CPU throttling. I used RMClock for this purpose during my first few months of E6400 ownership until Dell changed the BIOS to allow the E6400 with Intel GPU to run at full speed using a 65W PSU.

Check Ebay for "Dell PA-3E", and be sure to get a genuine adapter though. You should be able to find one between $20 and $30.
