Re: Dell latidue D610
The light indicator for the battery is; green-charging, yellow-battery failure, and red-charging system failure. The charging system failure happens when the power management chip fails. The pm chip regulates and controls the power input & usage, allows the machine to switch from AC to battery, and cotrols the charging. This will also cause the problem with the power button not workin or being hard to start. Unfortunately, the motherboard will have to be replaced in order to fix this.

Remove power completely from the device. If it is a laptop, remove the battery. Wait about 30 seconds for the power to drain, then reapply the power source.
If it's a laptop, you may need to let it charge 15 or 20 minutes. A desktop should power up just fine. If it does not, contact Dell immediately for warranty repair!
If this helped you, please give me 4 thumbs up!!
If your laptop won't power on or stay on for long then follow these quick and easy steps to troubleshoot the problem.
Ensure your battery is holding a charge. Some laptops will automatically shut-off if the battery won't hold a charge. In that case, replace your battery with a new one and retry. Check your charging lights or indicators to see if your laptop is getting power and charging.
Check your AC to DC converter (the little black adapter you plug in your AC outlet.) This converts AC power into DC power. Is it abnormally hot? If so, it is probably burned out. You will need to replace it. Note: High heat is not a true indicator of malfunctioning. It can be dead and cold as well. No power indicators on your laptop could be a sign of a dead or bad converter also. Converters WILL get hot (this is normal.) If it is REAL hot (burning hot when you touch it), then this is not good.
Check your power cord. Are there any nicks, cuts or kinks? If so, unplug it from the AC power and repair with electrical tape or better yet, replace it. Many computer salvage stores carry power adapter cords. They're cheap and could save you from electrical shock.
Check your laptop lid switch. If it is broken or not lit, you may have power but your screen may not come on. This is usually a little button located close to the lid hinge that turns on or off your screen when your lid is open or closed respectively. Normally the operator does not push this button. These are fragile and broken easily on some laptop models. Sometimes these can be repaired, more often they will require replacements. If you aren't an expert repair person, get a technician to repair or replace it for you.
If you have tried these easy solutions and it still won't power on, then your problem lies elsewhere. You may have an internal power switch or voltage regulator problem. Internal problems will require professional help so go on down to your local PC store and have a qualified technican take a look.
There are simple things that you can try first. Check the Monitor if it is turned on. There should be a light indicator if it is on or off. Usually it is next to the power button. Verify if the power cord is plugged in. Check the Video cable connector if they are tightly connected on both ends (tower and monitor).
Make sure the battery is charged. If not, plug the power charger and verify if its charging or not. If its charging, there might be a problem with your LCD. If its not charging, it could be a battery problem or charger problem.
The lightning bolt you describe is the laptop trying to accept a charge,
I'd also look at the charger, if the led on the charger is blinking,
there is a fault on the mobo charging circuit ( power not being able to
complete a circuit)
If you are lucky it could be the powerboard button connection to the motherboard, remove the powerswitch cover carefully and check for broken or crimped connections.
If removing the battery and running on ac power alone will not work, you may have a faulty dc port, and will need to replace it ( cheap enough).
After that, the indications are that there is a more serious fault on the motherboard.
it seems to be a problem with motherboard as you said you have replaced power supply and ac adaptor , try disconnecting external pheripherals do a flea power it doesnot start then you will have to replace motherboard
Dear Sir: We are here to help you and make able to fix your computer, however, we will need certain information, so we may proceed helping you: (1) The manufacturer of the Computer and/or the Computer Trade Name; (2) The Model Name and Number; (3) The Motherboard Identification Number. If you have trouble finding it, we can help you! (4) A detailed "report" of what happened. Please tell us what has happened so far. The light flashing is an indication of a problem, but we need a little more, like what happened before. Did you have your laptop out for repairs and a day after it stopped working? We need every detail you can give us, starting from the first signs, especially if you had someone else work on it. You said that after a day the computer does work. How did it stop working? Did it ever work on the second day? It has been many times, that a problem that you consider unimportant can be the solution to your problem! Also, after you had the second failure, did you turn your computer off, wait 20 seconds and then turn it back on. Sometimes one digit hangs up and it requires a re-start. Thank you for considering our service and the choice you made... CONSTANTIN (arzconst)
