Hi Jim!
First of all I'm from Sweden and I'm writing this 3 o'clock in the morning so there might be some spelling errors ;)

Yes, the powerswitch can be a real pain. since you need the schematics of your specific motherboard... to get this you need to know what model your board are. typically its written somewhere on the board with slightly larger letters/numbers than the rest, OR, if it's a typically brand computer (HP, COMPAQ, DELL, IBM etc.) with its original board you should be able to get the model number by just looking at some number on the computer case. example: DELL OPTIPLEX GX270 and seaching for that computer model on ther website. can't promise that they will give out any schematics though...but its worth a shot ;) If you cant find any schematics for your motherboard just post the model of your motherboard here and ill see if i can provide some feedback about it...

About the CD/DVD, try to boot with just 1 device powered up at a time, since basically CD's and DVD's are the same when it comes to interfaces like IDE. so either go with the DVD player OR the CD-ROM player to make it easier to find out whats wrong. After you have installed XP successfully you can try to connect/add the other device and boot up the computer again -XP should install it automatically.
Furthermore with the DVD or CD (whichever you want to try installing XP with). the cable connecting it to the motherboard and the DVD/CD should be in the SECONDARY IDE port on the motherboard (PRIMARY IDE port is for the HDD -Hard Disk Drive) and the jumper or "plug" on the dvd should be set as MASTER (should be a sign like "MA" or something, usually theres just those two pins that needs to be connected) there should also be others like SL for SLAVE and CS for CABLE SELECT but you wont need to bother about them. Master means the primary drive (the one that boots first on that channel, when installing win xp for example, this drive is the one that should contain the CD or DVD) Slave means a secondary drive - works as normal once in windows but is not preferred to install the base OS from. Cable is meant for the motherboard to decide wheter the device should be master or slave depending on which port on the cable it is connected to. also with the IDE cables; the port that are farthest away from the motherboard connector is the MASTER port. a rule which is not so clearly described.

You might need to enter the BIOS too to select the DVD drive as the default booting device in the boot order... usually its ranked from the top where the device on the top of the list is the one booting first.

Regarding the "NTLDR missing" (NT Loader) problem its just a file in the windows structure that is not recognized since you installed the OS (Operating System) in another computer.
Installing Win XP to a harddrive in anoher computer will most likely not solve your problem, as Win XP is based on the NT (New Technology) it isn't as flexible as older systems eg. Win 98. Your only real shot of succeeding in this matter is to simply install on the very computer that should hade this drive by default. (read: the computer your having trouble with)

Hope this helps out somehow, it would be nice to hear how this project ends up.

PS. For the record, my haircolor is blonde ;)
Hope this doesnt discourage you too much after reading this confession.

Best regards
Dan

There is no power switch on the enhance atx 1123b that I have . What actually powers it up?


Just about every power supply I've owned doesn't have a power switch. The power supply is turned on by one of the wires in the 24 pin connector. According to this it looks to be pin 16 and how to turn it on:

"Short this pin to GND to switch power supply ON, disconnect from GND to switch OFF."

Hope this helps

Put in new power supply, computer will not boot up. Asks what type of power supply, when I answer generic the computer will not continue to boot up. When I go into bios it says power supply is disabled and...


Try resetting the BIOS, depending on the motherboard, there will either be a button, switch or small jumpers that will short two pins and reset the cmos on the board. Just make sure to take out all the extra peripherals before powering back up. If you have jumpers, look for the one marked CMOS, not the one marked password. Move the jumper plug over one pin and power the system up. Wait approx. one minute and power back down, remove the power plug from the back and press the power button on the front to bleed off the power. Move the jumper back to its original place, plug the power cord back in and try booting the system back up. If it boots you will need to restart and get back into the BIOS and reset the time and date.

My t2862 powerlight will not come on but a green led comes on on the main board, nothing else happens. I also disconnected the pwr sw,hdd led and pwr led plugs and don't know which pins they go on. Thanks


On the front panel header where the wires connect, there are two rows of 5 pins. The top row actually has 4 pins with the end one missing, and the bottom row has 5 pins. The first two pins on the top row are for the power LED. The next two pins are for the power switch. The first two pins on the bottom row are for the hard drive LED, and the next two pins are for the reset button (if your machine has one). The LED connections are polarized, so if you get the connector backwards the LED won't light but it won't be damaged. Just turn the plug around and put it back onto the pins if your power light or drive light don't work.

Now, as to the computer not starting. Assuming the problem isn't due to the power switch not being connected correctly, you might have a power supply problem, or the motherboard has failed. Both are common troubles.

Here's a picture (from helpwithpcs.com) of the plug on the cable from the computer power supply to the main board:
a5427df.jpg
This is the view from the end looking at the front of the plug. If you connect the pin marked PS_ON (it's a green wire) to the black ground wire on either side (not directly across), the power supply will turn on and its fan start running if it's working properly. If it doesn't start up, replace the power supply.

If the supply starts normally, your motherboard is likely to blame. You can search online for a replacement if you want to use the exact part. Don't try to get one from e-Machines; there many other sources. You can also use any motherboard that will fit into the case (micro-ATX style) and uses the same processor and memory.

Mb have power but not start...


Hi, good day sir, there are several things you should do first.
1. Disconnect all connections to the motherboard.
2. make sure that your Power Supply 4pin 12volt molex and 24 pin molex connectors are tightly plug.
3. Clean the memory port from any dust, plug the RAM module, make sure also the module connector is clean.
4. Plug in the speaker and power switch.
5. Connect a VGA monitor.
6. Reset bios/cmos or simply operate the pc without the battery.
7. Plug the Power Supply to AC mains.
8. test the PC.
9. do this several times if you cant start the PC.
10. if every thing is OK, reconnect your PC and peripherals one at a time.
Hope this helps.keep me inform about your progress. thanks

Y computer will not start. I checked the power


Try booting from a rescue CD to see if the harddik is the culprit.
If you don't have one, try making one using instructions found at

Be sure to set Boot sequence to CD-rom in Bios.

Newly built system will not power up!


It seems like you have bad MOBO. I recently ordered all the stuff to build 2 new systems. Built the first one, no power, just like yours. Moved everything to the 2nd MOBO, everything worked. I did a RMA on the DOA MOBO. Got the new one and it fired right up. Sometimes you just get bad stuff.

Please don't forget to rate this solution.

Monitor comes on but wont show picture


You should make sure the cable is plugged into the video port on the back of the tower. Also, if you have more than one video card, ie an "onboard card" and another card that was added later, try alternating one to the other and see if the other one works. You can identify video ports by finding the blue pentagonal plug. It also will be the only plug that your monitor cable fits into (that is describing a VGA cable, a white cable is a DVI cable and is even easier to identify.) You might also want to make sure the video card wasnt jostled out of place. The final solution could be you have developed some bad memory modules, or the memory was jostled out of its slot during the move.

New video card wont work


The place to do this in bios is under the onboard devices area. Is there a power connection required for the new card? If so you would need to plug the 6 pin pci-e power connector to the power connection plug on the new card. If not required make sure your power supply supplies enough wattage to run the new card. Hope this helps.

Charger pin is plugged in but it doesnt charge neither does the charging lite turn on any idea? can be it a problem with BIOS ?


This is a common problem with the T20 & T30 series Thinkpads. The problem is with the power management chip on the motherboard. The pm chip regulates & controls the power input & usage, allows the machine to switch from AC to battery, and controls the charging. Unfortunately, you will have to replace the motherboard in order to fix it.
