How can I fix the Power button that quit working, even with new batteries?

Consumer electronics are not made to be repairable. Best get a new one.

You probably need a new receiver. Call 1-888-830-1326.

Try bypassing the power button by jumpering across the two terminals. If the set doesn't turn on, it's not the power button, it's something more serious. If it does turn on, just replace the power button with any momentary switch.

Chances are you have a bad solder joint on the little board. If youre handy you can fix it but if not then it needs to be replaced.

These are built very cheaply even though you pay good money for them they are designed and built at a minimal cost. I had problems with mine and finally threw it away and I am an electronics technician but it wasn't worth fixing. For what it is worth I have been using an MI wireless mouse for over a year now and it has been working fine other than replacing batteries occasionally.

It's the motherboard. Check to see if yours is still under warranty even if you've had it for over a year.

HP / Compaq has recently extended their warranty period for certain models.

Let me know if you have any other questions.

Unplug computer, disconnect all usb/monitor/internet, open it, hold power button until green led on the inside on the motherboard turns off, pop out the BIOS battery (looks like a big watch battery and use a small flathead screwdriver to depress the spring lock on one side), plug in computer, hold power button for about 20 seconds (must reset BIOS), let up on power button, wait 10 seconds and push power button. The computer should turn on. Wait for it until activity seems stable (1 min. or so). Push powerbutton to shut off.

If this has worked you have proven that it's not the power supply (it turned on). If you purchased a non dell power supply, you might try this with the original one installed.

Go buy a new battery (CR2032 3 volt). Unplug computer, open it, hold power button until green led on the inside on the motherboard turns off, pop in new battery, plug in (you should notice the power button blinking amber again), hold power button until it stops blinking (about 20 sec....again must reset BIOS), wait 10 sec., push power button. the computer should turn on. Wait for it until activity seems stabe (1 min. or so). Push powerbutton to shut off.

Now, close case, plug in all usb/monitor/internet/etc. Power up computer. You'll get an internal floppy drive error. Push F2 (maybe F1) to get into the BIOS settings and go to "drives" and turn off the internal floppy. Save and exit. The computer should boot properly now.

This seems to be a big problem with the e510, my theory is that this one small battery is the root of most of these failures (as these computers usually fail after 1-2 years), not the power supply or the motherboard (heck, when you replace the motherboard it comes with a new one of these batteries...a several hundred dollar piece of hardware, with a $5 battery that will actually fix it).

haha I have the same problem.

Sir,
you remove your Laptop main battery and adaptor for aprox 10 min then fix again battery and adaptor then on power button m/c is on.

push in the reset button on the back of the unit. Use the head of the stylis
