Delete Windows System Files

If you play around with Windows System Files sometimes it is not possible to delte them off after you had your fun.
The following commands will make it possible to force their removal:

For Files:

takeown /f file_name /d y
icacls file_name /grant administrators:F

For Directories (will perform action recursively):

takeown /f directory_name /r /d y
icacls directory_name /grant administrators:F /t

Of Course you need admin permission as always.

RAM SPD Burner

I wish to share with you guys this tool ThaiPhoon Burner, I was introduced to recently by der_mali of Notebookreview.
Quite a guy as he had quite a few tip and tricks up his sleeve.
I will not reinvent the wheel instruction of how to use here.

BEFORE I FORGOT, YOU NEED A SUPPORTED CHIPSET TO READ THE RAM CORRECTLY!
THE SOFTWARE WILL NOT RUN CORRECTLY ON CERTAIN CHIPSET.

I did as instructed and flashed both my RAM to PC2-6400 from PC2-5300 but Aspire 4530 only reads 667MHZ as shown in CPU-Z.
But the RAM timings improved and performance improvement for free is considered great.
Only thing I have to warn you is like flashing BIOS it can kill your RAM, so try to flash settings as close to your original RAMs as possible.
Take a look at my upgraded RAM originally it was PC2-5300 at 333MHZ
I even got in an EPP Profile!
In other words this Tool is a must have!

Simple Step by Step Guide:

1)You must run this software on a Compatible Chipset.

Certain NForce Chipset like the one on the Aspire 4530 WILL NOT work.

2)First extract this program to a location you find comfortable to run it in.

Right Click and Run as Administrator.

Agree to the EULA.

3)Click on EPROM, Read SPD at 50H or 52H if you have 2 RAM SLOTS occupied.

If you have 1 RAM SLOTS only either 50H or 52H will be available.
If it is read correctly you should see the Module Specification read correctly as shown above.

An example of incompatible Chipset is shown below.


First notice the numerous SPD displayed.

Next the Module Specification is incorrectly displayed.

Do not proceed if you encountered the above.

4)Next Click on Browser button.

Then Click on Download button.

It will proceed to download all the RAM dumps from the server as shown above.

5)Using the search parameter find the next closest update in RAM Specification

For Example you have a Kingston DDR2-667MHZ find the next closest DDR2-800 based on the

Module Code Number and Parameters.


Click Save Dump and save it to a location on your Harddisk

7)Next Exit the Browser Back to the Main Menu.

Select Open and Choose the Dump File you saved previously.

8)It should open up the Dump File details.


Choose EEPROM Select Full Rewrite.

9)You should see the Full SPD Rewrite Windows as shown below.


Select the correct SPD Device Address and click on write.

Wait for the process to complete and you are done!

Issue For Aspire 4530 Owners on Windows 7

Please take note when installing NForce Drivers
Make sure your Add/Remove Nvidia Driver has the entries below:

Use the 15.45 NForce Drivers I advised (Can be downloaded on Guru3d.com) DO NOT USE 15.37 NForce Drivers from Nvidia except for the AHCI Storage Driver from 15.37.
Note you get SMU Driver and PCI System Management Drivers, otherwise you get a Fatal Machine Check error occasionally in Windows 7 Event Log, you won't see any BSOD but the error log will be there .
In conclusion use the Storage Drivers from 15.37 and SMU and PCI System drivers from 15.45.

Update:
Please update the Storage Driver from 15.51 (from Guru3D) the driver from 15.37 causes occasional freezing issue.

Western Digital 320GB BEKT vs 320GB BEVT

Western Digital Scorpio WD3200BEVT

• Unfortunately my drive has failed so no direct comparison will be available. However I will run pretty commonly available tools (No Downloads required), to get the benchmark score so you can compare it to the BEVT in your laptop.

• 5400 RPM
• SATA 3 Gb/sec
• 12 millisecond seek time
• 8-megabyte buffer

Western Digital Scorpio WD3200BEKT

• 7200 RPM
• SATA 3 Gb/sec
• 12 millisecond seek time
• 16-megabyte buffer

First lets look at the built in test results for the Nvidia harddisk controller

Go Device Manager, under IDE controller you should see a Nvidia NForce SATA controller if you didn't then you did not install the SATA driver.
Go Nvidia website to download and install their Storage Controller Driver.

Test 1

Test 2

You can roughly gauge the performance by looking at the scores.

Next we run the WinSAT Detailed Test for more information how to run it see this post.

Windows 7 Boot Optimization Error

I am not sure if you guys know you can manually invoke Windows 7 defragmentation Tool to do boot optimization by using the /b flag.

When you run defrag.exe, you get the following

Microsoft Disk Defragmenter
Copyright (c) 2007 Microsoft Corp.

The parameter is incorrect. (0x80070057)

Description:

Locates and consolidates fragmented files on local volumes to
improve system performance.

Syntax:

defrag | /C | /E [/H] [/M | [/U] [/V]]
defrag | /C | /E /A [/H] [/M | [/U] [/V]]
defrag | /C | /E /X [/H] [/M | [/U] [/V]]
defrag /T [/H] [/U] [/V]

Parameters:

Value Description

/A Perform analysis on the specified volumes.

/C Perform the operation on all volumes.

/E Perform the operation on all volumes except those specified.

/H Run the operation at normal priority (default is low).

/M Run the operation on each volume in parallel in the background.

/T Track an operation already in progress on the specified volume.

/U Print the progress of the operation on the screen.

/V Print verbose output containing the fragmentation statistics.

/X Perform free space consolidation on the specified volumes.

Examples:

defrag C: /U /V
defrag C: D: /M
defrag C:\mountpoint /A /U
defrag /C /H /V

Notice there is no /B flag but it is there.
However on a fresh Windows 7 installation when you try to do this with Administrative Permission in a Command Prompt Window.

C:\Windows\system32>defrag C: /B

You get some message saying it cannot be done like the following:

Microsoft Disk Defragmenter
Copyright (c) 2007 Microsoft Corp.

Invoking boot optimization on (C:)...

Analysis: 100% complete.

Some registry entries were missing from the boot optimization section of the reg
istry. (0x89000017)

How to resolve this?
The issue is the idle tasks Windows is scheduled to run hasn't run once yet hence it cannot initialize boot optimization.
So to resolve simply open a Command Prompt Windows with Administrative Permission again and run the following commands to invoke the idle task.

C:\Windows\system32>Rundll32.exe advapi32.dll,ProcessIdleTasks
After that the error message will be gone and you can run boot optimization manually.

Why doesn't this happen sometimes?
Because RunIdle task is scheduled to run eventually after sometime of idle usage
if you do boot defrag immmediately after installation,
RunIdle task hasn't got a chance to run at all so you have to invoke it manually
if you want to start the operation immediately.

Acer Harddisk Failure

Firstly, if the Harddisk came from an integrated OEM System, the warranty is honored by the OEM.

The warranty is not going to be the responsibility of the Disk Manufacturer unless the Harddisk is bought separately in a retail store, so if you run out of warranty you will have to buy a separate harddisk replacement by yourself.

Symptoms of Harddisk Failure:

• Windows hangs while Booting or takes a unusually long time.

• Windows hangs while shutting down.
  

• BIOS hangs while booting. (To restore normal booting from a normal harddrive simply enter BIOS and set Clear NVRAM to yes, Save and exit)

• Windows Event log report S.M.A.R.T(Self-Monitoring, Analysis, and Reporting Technology) Failure. (A S.M.A.R.T Failure report definitely predicts a drive failure while not all drive failure will definitely be detected by S.M.A.R.T)

• Linux Desktop suddenly colour corrupts and doesn't respond at all.

How to resolve:

1. Boot from a Linux Live CD and copy all your important data to an external harddisk. (Do not attempt to boot from the failing harddisk, it only makes thing worse)
2. If you have a desktop and the notebook harddrive uses a SATA connector you can simply plug your notebook harddrive to a connector, boot from the desktop harddrive and copy the data off the notebook harddrive.
3. If the notebook harddrive uses a PATA connector then you need a bridge.
   
4. If the harddisk has failed totally it is impossible to retrieve any data unless you go to a specialized data retrieval centre which usually cost a bomb.
5. Do not go to those small computer shops that claims they can retrieve data, because they do not have the actually tools to do a platter swap to retrieve the data or recondition the harddisk, they are only out to cheat your money)

Yes I was unlucky enough to encounter a harddisk failure however I managed to salvage all the data I needed to a new Laptop Harddisk.
The new harddisk is considered a upgrade from WD BEVT Scorpio Blue to WD BEKT Scorpio Black.

The new harddisk spins at 7200RPM instead of 5400RPM and has a 16MB Disk Buffer instead of a 8MB disk buffer.
It also comes with a 5year warranty instead of a 3 year warranty.
The slight price difference justified the upgrade purchase.
Oh, and by the way the BEKT reports a 5.9 score in Windows Experience Index.

How To Choose What Laptop System To Get?

Basically there are only a few questions you need to ask.

1.Size

How big you need your laptop to be?

Keep in mind size is related to weight, the smaller the laptop the lighter it usually is.

<12.1>

13.1 inches (Mainstream Laptops)

14.1 inches (Mainstream Laptops)

15.1 inches (Mainstream Intensive Gaming Laptops)

16.1 inches (Desktop Replacement)

>16.1 inches (Desktop Replacement)

Usually if you need to move it around 14.1 -15.1 inches would be around the max for mobility.

2.Usage

Processor

Intel

For Intel Processor typically it is easily identified
Intel Core i (Processor Class Number) - (3 Digit SKU Number)(Alphabet 1)(Alphabet 2)

The Processor Class Number is either 3/5 or 7.

3 refers to the low end Processors
5 refers to the mainstream Processors
7 refers to the high end Processors

The 1st Digit SKU Number refers to the instruction set in the Processor.

3X0 means

1. No Intel® Turbo Boost Technology,

5X0 and above

1. All Instruction Set Supported

The 2nd Digit refers to the different Frequency of the Processor Family

For the alphabet there are a number of fixed Alphabets

M - Mainstream
Q - Quad Core (4 Cores, 8 Threads, No Intel HD Graphics due to high TDP)
X - Xtreme (Unlocked Multiplier)
U - Ultra Low Voltage (Low Frequency + Low Voltage)
L - Low Voltage (Low Voltage only)
E - Embedded (Not Upgradable)

AMD

For AMD Processor it is not as easy.

Generation Griffin

Identifier:
AMD (Model) X(No. of Cores) (SKU Alphabet)-(Frequency Identifier No.)(Odd/Even Last Digit)

1. Turion refers to high end model
2. Athlon refers to mainstream model
3. Sempron refers to low end model

Ultra refers to Total 2MB L2 Cache otherwise 1MB L2 Cache or less.

ZM refers to Turion Processor with 3 Power State
RM refers to Turion Processor with 3 Power State
QL refers to Athlon Processor with 2 Power State
SI refers to Total 512 KB Cache with 2 Power State

Frequency Identifier No. starts from 4X to 8X.

1. RM-70 starts from 2GHZ (Every 2 increase Frequency Increase by 100MHZ ) Odd Last Digit refers to an increase in HyperTransport Frequency from the Even Digit SKU  
2. RM-80 starts from 2.1GHZ (Every 2 increase Frequency Increase by 100MHZ ) Odd Last Digit refers to an increase in HyperTransport Frequency from the Even Digit SKU  
3. V refers to Low Voltage Processor

Generation Caspian

Identifier:
AMD (Model) (Generation II) Ultra (No. of Cores) (Type Alphabet) (3 Digit SKU No.)

1. Turion refers to high end model
2. Athlon refers to mainstream model
3. Sempron refers to low end model

Generation II refer to K10 Architecture

Ultra refers to Total 2MB L2 Cache otherwise 1MB L2 Cache or less.

Type Alphabet

1. M refers to Mainstream
2. L refers to Low Voltage

3 Digit SKU

6XX refers to Turion Ultra Series Starting from 2.4 GHZ, every increment in 20 increase by 100MHZ with 5 Power States
5XX refers to Turion Series Starting from 2.2 GHZ, every increment in 20 increase by 100MHZ with 5 Power States
3XX refers to Athlon Series Starting from 2.0 GHZ, every increment in 20 increase by 100MHZ with 3 Power States

Note Starting Frequency of L Series differ from M Series

Generation Champlain

 

The Generation Caspian adds Quad Core Mobile Processor to the market.

Identifier: X NNN
X is either X for Black Edition (Unlocked Multiplier 45 Watt TDP ), N for MainStream (35 Watt TDP) & P for MainStream Lower Power Consumption (25 Watt TDP), V for Low End (25 TDP Single Core).

1st Digit refers to SKU
9 - Quad Core with 21.3GB/s HyperTransport

6 - Dual Core with 21.3GB/s HyperTransport
5 - Dual Core with 17GB/s HyperTransport
3 - Dual Core with 64bit Floating Point Unit (I suspect it is the old Caspian Refresh) (All the new Champlain should have 128Bit Floating Point Units) 17GB/s HyperTransport
1 - Single Core with 64bit Floating Point Unit

All Champlain Generation has 0.5 MB L2 Cache per CPU Core.

Graphics (For Gaming GPU > CPU)

For occasional gaming get at least some decent graphics from Nvidia, ATi.

For Intel Graphics if you must at least go for 3150,4500MHD or the new Intel HD Graphics.
They have Video Codec Decoding Abilties for Adobe Flash 10.1.

For ATi any Radeon HD will do, DO NOT go for Radeon Xpress they are obselete.

For Nvidia, go for anything below 8000 Series. 7000 series are obselete.

Both Nvidia 7000 Series and Radeon Xpress do not support GPU computing and DirectX 10

Use Notebookcheck as a rough guide for gaming performance.

Class 3, Class 2, Class 1 are suitable for occasional gaming.

For more intensive gaming consider getting Class 2 and Class 1 Graphics however they are most available only on 14.1/15.1 inch and above laptops.

Reason being more powerful graphics requires more powerful fansink these contributes to size hence usually they can only be found on 14.1 inch and above systems.

RAM

I don't really bother as it is very easy and cheap to upgrade laptop RAM.

You get more cost saving upgrading RAM yourself than buying a high RAM laptop.

Harddisk

Size is of no concern as they come with at least 120GB and that is more than sufficient.

Edit:
With regards to how good a laptop is in terms of quality you have to look at the design layout.
1) Google the motherboard prints of the particular laptop
2) Heatsink size must be sufficiently large enough particularly for AMD Processor Laptops and those with Nvidia/ATi GPU, larger mass allows higher heat capacity so temperature will not be too high.
The GPU, CPU and Northbridge must not be too close to each other.

3) The capacitors must be of high quality

High Quality Capacitor
Lower Quality Capacitor
