The core computer BIOSes are created by a small number of companies https://en.wikipedia.org/wiki/BIOS . Computer manufacturers then licence a...
I can't think of a good reason why a board from a different version of the NP900X3C wouldn't work. I exchanged the mainboards between UK and...
Sorry for confusing you. I had to take my business elsewhere after Samsung withdrew from the European notebook market. There are two ways to...
I definitely did that swap. Dell probably designed the board to support both options as, at the time, there was a big price differential between...
If you can touch type and /or are frequently swapping between your notebook and a desktop (or other computer with a full-sized keyboard) then...
If you are referring to the new 7400 then the manual says the keyboard is full size with a key pitch (center-center measurement of 19.05mm. Also...
I think you will find that the keyboard on the 73xx is about 95% of full size which, in my experience, doesn't impair usability. John
Yes. :) If you keep the UPS plugged into the mains then it will keep itself fully charged and ready for a mains power outage. I've got my...
My approach would be to leave the laptop plugged into the UPS so the UPS's battery gets drained first. When the UPS shuts down you still have a...
Fully charge the UPS, plug the computer into it then disconnect the UPS from the mains. The computer will then use the power from the UPS until...
Yes and keep that setting for your normal (Balanced?) power plan. However, I would suggest that you go through the options for the Power Saver...
Set the battery option to 99% but leave the mains option at 100% when using mains power. However, if you are using an external battery then you'll...
Yes, use integrated graphics when not running on the mains in order to conserve power. The Nvidia GPU uses a lot of power. That said, do some...
I've come late to this discussion but the two parameters you need to look at are battery capacity (Watt-hours) and maximum power output (Watts or...
Would you be meaning "replace NP900X3C Mobo with NP900X3D or later?"? The X4D is a the larger machine and the board layout is different (eg only...
Try this. I found it by going to the E6510 drivers, expanding the BIOS entry, then clicking on Older Versions (which triggers a pop-up window)....
It all depends on how fast your XPS guzzles power. Can you, for example, throttle back the performance when the mains power fails? Draining a...
New BIOS 1.10.0 marked "Urgent" for the 5510. "This update addresses the Intel security advisory INTEL-SA-00185." There's also an updated...
I don't know but it won't hurt if you add the registry entries in both places. John
Separate names with a comma.
