I have an emachine T2642 desktop and I need to replace the battery. Where is the location to replace the battery


A desktop machine does not have a battery, only a power supply. Unless you are talking about the motherboard battery which is located on the motherboard inside the desktop, but if that is the case I highly suggest having someone at a local shop swap out your battery. Making a mistake could ruin the motherboard.

Hello, I have a T2642 and my motherboard is not working. I removed the hard drive and installed it into another computer with windows xp that has a 40 gig hard drive with it. we put the T2642 Harddrive...


Password protected or not, data is data and will take up space regardless.
It is a strange one. Did you say that the drive worked and can boot from in another system? If it did then this pc is having problems. Even if you view the drive with a different OS the data will still be there.
Very odd.

What are the hardware requirements for this motherboard in the way of memory, and graphics card? I have a pc2700 256M chip that is only seeing 191M of the total ram. Does it require ddr pc2100 instead? And...


Jeff, some of the system's ram memory is being borrowed. If you are using Integrated Graphics, this is where it is going.

[Integrated Graphics is also known as OnBoard Graphics.
On the motherBoard.

The GPU is soldered to the motherboard. (Hence you plug the monitor cable into the motherboard, via a VGA connector,

http://en.wikipedia.org/wiki/VGA_connector )

A dedicated graphics (adapter) card has it's own GPU.
(Graphics Processing Unit,

http://en.wikipedia.org/wiki/GPU ]

Integrated Graphics uses some of the system's resources. The Processor, and Ram Memory.

A dedicated graphics card has it's own Processor, and Ram Memory.
(GPU, and graphics ram memory)


PC2100 is DDR Sdram that operates at a frequency rate of 266MHz.

PC2700 is DDR Sdram that operates at a frequency rate of 333MHz.

http://en.wikipedia.org/wiki/DDR_SDRAM

[Frequency Rate:
Proper 'computer speak' for Speed.
'Speed' is slang.

DDR Sdram:
Double Data Rate Sdram
Synchronous Dynamic Random Access Memory

MHz.
MegaHertz
Mega = Approximately 1 Million
Hertz stands for Cycles per Second.

PC2100 can operate Up To a frequency rate of 266 Million Cycles per Second.
PC2700 - 333 Million Cycles per Second ]

No, using PC2100 is going backwards, and will not help increase the Amount of ram memory, seen by the computer.

According to eMachines Support, the T2642 desktop computer's motherboard, uses an Intel 845GV motherboard chipset.

http://www.emachines.com/support/product_support.html?cat=Desktops&subcat=T%20Series&model=T2642

[Chipset, and Chip are slang terms for I.C.
Integrated Circuit.

The motherboard chipset used for the technology of the T2642 motherboard, is the Northbridge, and Southbridge chipset.

(Motherboard's for the Intel Core i3, i5, and i7, do not use this motherboard chipset technology)

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

(CPU = Central Processing Unit. Another term used is Microprocessor, or simply Processor for short.
Memory Slots = Ram Memory slots ]

The Northbridge chip handles the faster processes of the computer.
The Processor, Ram Memory, and high speed graphics.

High speed graphics being AGP, or PCI Express.
Not a graphics card inserted into a PCI slot.

Integrated Graphics, or a graphics card inserted into a PCI slot, is a slower process of the computer.

Slower processes of the computer are handled by the Southbridge chip.

Northbridge (computing)

vhttp://en.wikipedia.org/wiki/Northbridge_%28computing%29

(At the end of the Northbridge article's first sentence, you will see - southbridge, in blue.

Old emachine T2642 will not boot...disk monitor LED stays on and CPU fan does not rotate...no boot access to CD-ROM, or disk drives...changed power supply...think it might be BIOS backup battery...


It sounds like a dead motherboard. Try removing the CMOS(BIOS) battery and replacing it. Then try removing and replacing the CPU as well. If you get the same result then you might be looking at replacing the motherboard.

Emachines T2642 Motherboard


It's either a dead power supply or a fried motherboard. Emachines are cheap junk, their power supplies and motherboards die all the time, just look around here on Fixya for proof. Instead of saving a buck, consider buying a better brand.

I have an Emachine T2642.hears a pop and the power went out on pc


As long as your hard drive didnt go, you will still have all of your files. Chances are your Motherboard blew. Motherboards have capacitors so they can make popping noises if they blow

Emachine t2642 power supply


Apparently this model has a bad motherboard, which manifests as a power warning and eventually a refusal to boot up. You can replace the power supply (as far as I know, any generic one 250-watt or better will work) but it's unlikely to help. You can buy a new motherboard (and new power supply, if you want to) direct from eMachines, but it's also likely to fail pretty soon. Your best bet is to get a new computer (NOT an eMachines one) and put your hard drive in as a slave so you can get your data off.
