How to extend the battery life of your laptop without losing power: Reduce the processor voltage


Earlier we saw how to extend the battery life (and the computer to overheat less, also extending its life) tweaking the settings of the graphics card . This time we will do the same, but without any danger to your computer, without slowing it , lowering processor voltage. 

Did you know that it will continue working as before and safely? Indeed. And I'll explain why. 

Assemblers buy computer components (including the processor, AMD, Intel, or whatever) and then merge them into assembly. However, when making the processors are produced in batches of thousands of units, and each comes with its own characteristics (may have tiny defects, with a different quality, which may slightly affect the performance of each) a particular "batch" sample is tested, and labeled with the voltage required to operate safely and without fail, usually with a large margin of error. 

We will find out what the lowest safe voltage possible for each processor operating frequency that our laptop mounts, and apply it using a program (RM-Clock for intel or AMD K10Stat for K10), so our team will to do the same job, but with less energy, less warming, lengthening its life, and thus making the battery last longer. It sounds complicated, but you will see that it is not. 

This applies especially to older processors; for current (Phenom, I3 / I5 / I7) can not find them programs that can configure or that you have to make the change through the BIOS (I think that Intel now are marked with fixed voltage factory without the possibility of change "on the fly").

Changing the display cable on a laptop

Acer Aspire 5930G with the display cable fixed
Earlier I commented that in several ACER laptops the picture failed by the cable, and the solution to tighten the connection area does not give permanent results, so sick of the problem, ordered a new cable from Ebay. 15 days later it came to me:


In this post we will see the steps to take to change the cable screen (make that is the problem before changing; it is not the most common).
This guide will give us the necessary guidelines to disarm any screen, since all are constructed similarly.

How to Install Windows 7 on a Compaq NC8430

Today we are going to install the best current Windows; 7, in this somewhat dated computer but with a Centrino Duo that can cope with the Win7. I've found that does not have the drivers for the hard drive, so I had to go to the manufacturer's website, HP, and download the AHCI Sata hard disk controller. 
To copy it to a USB need to burn it to a floppy, and as I don't have this anymore, I have had to do with a virtual floppy using an USB pendrive.
