E6510 DC adapter

Does the E6510 computer require a 90W DC adapter or will it work on a 65W adapter??

 

I believe it should work on a 65-Watt adapter but the charging capability will be handicapped. I am running the E6410 on the 90-Watt adapter and the adapter is considerably smaller then the D-series latitude adapters I am familiar with.

 

If you have the Intel GPU then 65W should be OK (it is for my E6410 with Intel GPU) but if you have the Nvidia GPU then the BIOS will probably throttle the CPU.

I thought the GPU was usually the component throttled when the adapter cannot supply enough power.
Either way something will likely get throttled.

warning: OP if your buying a generic power adapter, never charge the battery while using the laptop. Generic power adapters will fail if they're stressed too much. Always leave the battery out while using it, or disable charging via bios or fn key.

If it's an original Dell Adapter, it should be of sufficient quality and should be fine.

 

In practice, I'm seeing a power draw that exceeds 75 watts even with Intel graphics.

I really think that Dell is issuing 90 watt power adapters for a reason.

 

My observation is that is possible under full load + battery charging. If only a 65W PSU is present, the charging rate gets reduced to stay within the PSU limit.

Yep, thats what it does. I have the travel adaptor and its only 65w. The computer works fine but battery charging is VERY slow. Full charge can take 8hrs or more if the computer is running. Turned off, it charges in an hour or so.

Other thing that was odd, Dell is supplying the older rounded corner power supplies with some E6410s, they must have a shortage of the newer smaller supplies. One phone call got it replaced but several have had the old style in the box.
