Question about Intel Core Duo T2600, 2.16 GHz Core Duo (BX80539T2600) Boxed Processor

Laptop will not power up!

When I press the power button on my Dell Inspiron E-1705, the power light and blue tooth light both come on for 5 seconds and then go off. No hard drive activity, no beeps no video, no disk drive activity or lights! I have swapped memory, removed hard drive and tried to boot, used an external monitor, tried a new power supply and battery, tested both fans for CPU and video card, reseated everything several times, replaced heat sink compound (it turned to dust when I removed the cooling coil from the top of the CPU), replaced mother board, replaced video card, checked for poor ground locations! Nothing!
The thing died about 3 months after warranty from dell ran out. Is the CPU the only thing left to replace? I am hesitant for obvious reasons ($500) but I don’t know anything left to check. This thing just locked up one morning and I had to hold the power button to power it down. It came back up for an hour or so and powered itself back down. I then backed info up and dumped the op. system, reloaded everything and it ran all day with no problems, noise, or alarms and was running faster then it did out of the box! Then after I got everything back to normal and powered it down and back up, it wouldn’t boot, only after removing all power sources for 18 – 24 hrs. would it boot, but after the dell screen it would just die. No beeps no noise, now it won’t do anything. The power led and blue tooth light up for 5 seconds and then just go off. I have been trouble shooting this thing for 4 months now and am at my braking point. Can someone please help me!?

Re: Laptop will not power up!

I am having the same freaking problem. I took out my cpu and looked at it, the side by the last row of pins are blackened a little. it looks like something burnt it up. I am now looking for a new one, but cant find one on ebay., They look pretty cheap though. I think this might be the same problem your having. Anyways email me and if I find out anything else ill let you know, and if you figure out what might cause this let me know.
thanks my email adress is

Re: Laptop will not power up!

If you have replaced the motherboard I would say it is most likely the CPU. If you had not replaced the m/board I would think it was one of the power chips on the board that sends power to the cpu. If the heat sink compound had turned to dust on the top of the cpu that is certainly not going to help with cooling the cpu down. $500 sounds awful pricey for a CPU. What type and speed is it? May be able to dig one up for you in the basement that will work. At least for testing purposes. Post your type and speed of cpu that will work in your laptop.

Black spots laptop screen

Pinpointed spots can be damaged pixels that no longer light up when energized. They cannot be repaired and you will have to live with them, or get a new display. Try to use the Color Adapter port to a standard LCD Screen. On the side of the computer is a small 9 pin (usually blue) port whereby you can attach a desktop monitor as an alternative to the LCD Panel on the laptop.

Dell Laptop not powering up - emitting 3 beeps

see p.47 of your manual
This says 3 beeps means "Possible system board failure - Chipset error" which sounds serious. Are you certain it is three beeps ? The manual recommends contacting Dell (see contacting Dell on p76). Inspect each chip on the m/b for damage (you may not find anything). You might try disassembly and reassembly of the computer (see Service Manual on Dell website) if you are competent to do this, and cleaning it out with a can of compressed air.

Test your PSU power supply unit or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle of restarting or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive power and data cables IDE SATA

the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty

make sure all leads that are attached to your dvd\cd floppy drives have secure connections and are not faulty or just replace them they could be faulty

computers need power and data to travel through every working device to continue its cycle and have an end so any faulty leads will end up with a computer error

even something as small as a faulty electrical or fan lead can cause you problems

motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail

check all electrical power input and extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working

also check the Cmos battery and computer RAM modules make sure they are securely seated with no dust built up or in the sockets on some motherboards cmos batteries are soldered in

check you CPU central processing unit make sure its securely seated and has thermal paste it might be getting to hot the thermal paste will help disperse the heat

Thermal compound is a sticky paste that is placed directly onto the CPU.

Allowing for a more direct heat transfer between the CPU and HEAT SINK and preventing air gaps from forming between the CPU and heat sink.

hope this helps

No power

This might work. Unplug the power cord connected to the back of the PC. Press & hold the start button on the PC case for ten seconds. Reconnect the power cord & try starting the PC. Still no power. Connect the power cord from the PC directly to a wall jack. (No power strips). Still no power? Possible the power supply went bad.
