Laptop Powercord Problem

I am running a HP nc6400 with a intel Centrino Duo processor. When I plug in the power cord, the cpu usage according the the taskmanager goes from 0 to 100% and everything is really laggy. When unplugged it runs perfectly fine and the cpu usage is usually at 1%. What is happening?

There is a virus infection you need to scan system and have to check the power cord plug in a fix plug no sparking at all should be there.

Can I upgrade my DV7-2173cl processor to one that supports virtualization (vt-x or vt-d). Processor is: 2.00 GHz Intel Centrino 2 Processor Technology featuring Intel Core2 Duo Processor P7350


Would be quite challenging. From cost perspective it may be good to get a new laptop rather than trying to upgrade. Also the n1000c is rather old and compaq or HP doesnt support it. So perhaps you can consider investing in a new laptop :)

What to do next after upgrading CPU


Hey;

Start your computer and right after the hp logo, keep pressing the F8 button until you see a large list of options.

Select

"USE LAST GOOD KNOWN CONFIGURATION"

and press enter. Let windows load and it should work just fine.

What is difference between centrino and pentium m??????


Processor wise there is no difference, Centrino is just a branding initiative by Intel and it consists of..
Pentium M Processor(now with the release of the Core Duo/Solo, they are also included)
Intel Chipset
Intel Wireless
If a laptop uses all of these parts then it is branded as a Centrino and you get a "Centrino" sticker slapped onto the laptop. If one of them is different then you get the regular Pentium M sticker.

There is no other 'real' benefits of being branded as a Centrino. It is just one of the many marketing tactics used by Intel.

IBM ThinkPad R40 Intel Centrino Upgrade to Intel Core 2 Duo?


According to system specs your system is not compatible with the Core 2 Duo or Centrino Core 2 Duo. To upgrade to those chips you would need to replace the motherboard with one capable of running those chips. If you decided to do that you would almost surely need new RAM as newer boards use newer technology. By the time you did this the upgrade would not be cost effective. Hope this helps & please remember to rate my answer. Thanks.

My hp compaq nc 6320 is running at 987mhz


I believe the Centrino Duo steps the processor down to save energy when unplugged. Try restarting the computer with it plugged in (if it isn't plugged in now). You might be able to change or disable this function in the power management program if this turns out to be the issue.

Slow Cpu speed


Check in the BIOS to see what processor is rated at (upon power-up of laptop hit F2 key to enter setup menu). Depending on what model Centrino you have, the speed rating should be at around 1.2 GHz or better. If speed checks out in the BIOS then run diagnostics on laptop to see if the motherbrd has a bottleneck issue. To do this, hold down the <FN> key and then push the power on button. Problem could be either your processor or motherbrd.
