What is a replacement Battery Modle Number for ASUS A53T CPU AMD A6-3400M 1.4GHz

I think that in your laptop, the wireless transmitter can be toggled between the ON and OFF states by the pressing the function key and the F2 key at the same time, i.e. <FN> + <F2> or .

If you do not have the manual, which would tell you. check the Asus website

Replace cmos battery? Charge battery? Then replace AMD cpu?

asus makes the Best mainboards in my opinion, All AM3 boards. You get what you pay for so it's worth spending a bit more to get a good mainboard.

Example: ASUS M4A88TD-V EVO/USB3 is a really good option, however I myself would pair this mainboard with a AMD Phenom 2. Though your X3 450 will work well in this mainboard too.
The best compatible mainboard would be the ASUS Crosshair IV Formula or Extreme edtion, however your CPU will be a bottle neck in the system.
The ASUS M4A88TD-V EVO/USB3 is really good looking and it performs really well too.

You could go for an ASUS 785/790/870/880/890 North Bridge chipset AM3 Socket.
You could even purchase an AM3+ mainboard that will support AMD's new Phenom module CPU's.
Go to www.asus.com and check out the AMD mainboard range that they produce.

Take care!

could be a number of things.try totally different memory, cpu, motherboard. swap things out til you find the one thats the culprit.

Here is the CPU Support list from Asus Support, for the Asus A7V266-E,
http://support.asus.com/cpusupport/cpusupport.aspx?SLanguage=en-us&model=A7V266-E/AA&product=1&os=17

Scroll down the list. 34th one down, that is listed.

1.Did you get the Athlon XP 2600+ that has a 266MegaHertz, (MHz), Front Side Bus? (FSB)
The AXDA2600DKV3C?

There is an Athlon XP 2600+ that has a 266MHz FSB, and one that has an FSB of 333MHz. <-This one Won't work.
Model number ->AXDA2600DKV3D will Not work.
Both are Thoroughbred A/B Core models.

The AXDA2600DKV3C has a 12.5x multiplier.
Your 1900+ has a 12x multiplier. (AXDA1900DUT3C) They both have an FSB of 133MHz. (Shown as 266MHz because AMD processors are 'Double-Pumped')

A.The AXDC2600DKV3C will not work. It has a 16x multiplier. (Thorton Core)
B.The AXDC2600DKV3D will not work. It has a 333MHz FSB. (Thorton Core)
C.The AXDA2600DKV4C will not work. It has a 15x mulitplier. (Barton Core)
D.The AXDA2600DKV4D will not work. It has a 333MHz FSB. (Barton Core)
E.The AXDA2600DKV4E will not work. It has a 400MHz FSB. (Barton Core)

2.Are the jumper blocks -> CPU RATIO, and SYSCLK, still set in the Jumper Free Mode?

By the factory default settings these jumper blocks, (DIP switches), should already be set to Jumper Free Mode.
The white DIP switches should be in the OFF position. (The white switches will be DOWN, towards the numbers on the jumper block CPU RATIO. They will be UP, away from the numbers, on the jumper block SYSCLK))

The CPU RATIO jumper block is right above the processor. It is a blue rectangular block.
The SYSCLK jumper block is down the motherboard, right below the AGP graphics card expansion slot. (And above the first PCI expansion slot)

If those two jumper blocks are not set to Jumper Free Mode, set the DIP switches in the jumper blocks to this setting.

Now go into BIOS Setup. In the main menu use the Right Side Arrow key on your keyboard, and highlight Advanced.
If -> CPU Speed is set to Auto, you won't have access to set your CPU parameters. If it is set to Manual, you will see them. If it's set to Manual, write down the headings, (CPU:System Frequency Multiple, System/PCI Frequency (MHz), and so on) Write down the numbers to the right of these headings. If something goes wrong, you can go back into BIOS Setup, and change them back.

1.CPU:System Frequency Multiple should be
12.5X
2.System/PCI Frequency (MHz) should be
133/33
3.System/DRAM Frequency Ratio should be
(Auto)
4.CPU Vcore should be (1.750)
5.CPU Level 1 cache, and Level 2 cache should be (Enabled)
6.CPU Level 2 cache ECC Check should be (Disabled)
7.BIOS Update should be (Enabled)
8.PS/2 Mouse Function Control (Auto)
9.USB Legacy Support (Auto)
10.OS/2 Onboard Memory >64M (Disabled)

Leave the rest alone.

The AXDA2600DKV3C uses 1.65 volts, has a 12.5 clock multiplier, and a 266MHz FSB. (You will see 133MHz, and set all your settings to 133MHz. AMD processors are 'Double-Pumped'. Intel processors are 'Quad-Pumped')

The Ol' Asus A7V266-E?
1.The fastest Front Side Bus setting is 266MHz
2.Uses Socket 462 AMD processors
3.Uses Athlon, Athlon XP, and Duron AMD processors.

I would stick with an AMD Athlon XP. Fastest one? Hmmm, I believe that would be the AMD Athlon XP 2600+
The one that operates at 2133MHz with a FSB of 266MHz. Part number AXDA2600DKV3C

Here is the Motherboard Manual for your Asus A7V266-E, (It's a PDF file download. Let it download all the way before looking through it)
http://www.motherboards.org/files/manuals/1/a7v266e-100.pdf

If the above direct link does not work for you, then go here,
http://www.motherboards.org/mobot/manuals/ASUS/A7V266-E/ (Click on -> Download <- all the way to the right of -> File:a7v266e-100.pdfVersion:--Release Date:--)

Go to Page 19, Item 2. NO POWER connected to computer, make sure the SYSCLK (System Clock) DIP switches are set to 133MHz.
1, 2, 3, and 4 are set to the OFF position for 133MHz.
All you will see is the ON. The switches go to the opposite side as shown in Item 2.

I'm sure they are set there however, as your 1900+ you have in right now, uses a 266MHz FSB.
I should explain.
AMD processors are Double-Pumped. Therefore the 133MHz setting will become 266MHz for the processor. (Intel processors are Quad-Pumped.

They are both the same Core, (Thoroughbred A/B, Model 8, 130nm), so a BIOS update shouldn't be necessary.

the following motherboard are best for the processor u have:-

MSI K9N6PGM2-V Motherboard CPU Bundle - AMD Athlon 64 X2 4200+ ...

Asus M2N-MX SE Plus Motherboard CPU Bundle - AMD Athlon 64 X2 4200 ...

ABIT-AV8 MOTHERBOARD AMD ATHLON 64X2 4200+ DUAL CORE

selection is yours.

you should be able to press F2 or Del on boot up to get into the bios, but you should replace the battery first then set everything up as the cmos has obviously lost it's saved settings because the battery is flat.
