Inside a Sony Vaio VPCCW1S1E

This is one of the easier Sony Vaio’s to get into. Undo all the screws on the bottom of the laptop. Remove the battery, hard drive and DVD drive and the base separates away from the keyboard part. There is a clip above the memory that attaches the cable from the USB ports to the motherboard. Undo this before separating the two halves.

Clip fits in here. Attaches USB ports to motherboard

Asus K53E laptopIn this article I am going to show you how to inspect and remove dust and dirt from inside an Asus K53E laptop. I will also show you haw to remove the DVD drive from the Asus K53E as it is not like other laptops in the fact that the retaining screw is under the keyboard!

This will take less than one hour and is one of the easier laptops to take to pieces 🙂

Note how close the heat exhaust is to the charger socket. If the exhaust is blocked the build up of heat will effect the charger socket possibly making the charger plug feel hot.

How to fix System Fan (90B) error on a HP Pavilion G6 Laptop

02 HP Pavilion G6
This article explains how to resolve a System Fan (90B) error from appearing when you start up your HP Pavilion G6 Laptop. The full error reads:

The system detected that a cooling fan is not operating correctly

And looks like this:

HP Pavilion G6 System Fan 90B

HP Pavilion G6 System Fan 90B

The error is caused by the system cooling fan not spinning. Notice I said “Not spinning”. The most likely cause is that the fan is stuck or has fell off its spindle. Rarely are any new parts required for this fix but you will need thermal compound paste as you have to remove the heat sink from the processor.

In this example I have used a HP Pavilion G6 but this article is also applicable to many other laptop models as well as the CQ series from HP Compaq.

This procedure should take less than one hour. You do risk damaging the fan but it may be all that is required. More likely you are going to have to take the laptop apart which is described as follows:

Sony plugged in, charging but still reading 0% charged

I bought a compatible battery for a Sony VGN-CR42S laptop but it would not charge. After a little trial and error I found it was down to a Sony application called ISBMGR.exe. This is located in the Sony programs folder. Rename this, restart the computer and hopefully your compatible battery will be charging properly 🙂

On a 32-bit machine the file is in C:\Program Files\sony\isb utility\

If you are on a 64-bit pc then the file is in

C:\Program Files (x86)\sony\isb utility\

When you download a files your browser always says it is a virus

A computer had been infected with a virus. All traces of the virus I removed but when I went to install the free version of AVG Internet Explorer told me the installation file I downloaded was a virus. I also tried to download the file via Google Chrome.

To stop this from happening a registry edit was required:

Open regedit via the command window.

Navigate to:

HKEY_LOCAL_MACHINE> SOFTWARE> Microsoft> Windows> CurrentVersion

and rename “Policies”

After the computer is restarted the download worked as it should
