My T22 cannot not start. When I connect the AC cord to the laptop, the battery lamp turns green. I then press the POWER ON button, both the HDD lamp and battery lamp flash for less than 1 second (none of the other lamps flash), then only the battery lamp remain green.
Any expert can advise me what is the case? Thanks very much.

Re: My T22 unable to start
It is possible that the battery has been so depleted that it gobbles up all the power from the charger/adapter and leaves nothing for the laptop to use. Perhaps what you can do are: 1. try and charge the battery at least overnight with the laptop off; 2. use the adapter/charger only and remove the battery from the laptop.
Hope this be of help. Pls post back how things turned up or should you need additional information.

When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?
When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.
Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.
Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.
Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.
The RAM module may be faulty or just need reseating to make proper connection. Try reseating the RAM modele/s and if this does not work then remove the RAM module/s and take them to your friendly computer repair shop and get them to test your RAM.
This sounds like there is a problem with the battery. Remove the AC mains power and take out the battery from the laptop. Plug AC power back in and try booting the laptop up. If it boots up let it boot into Windows/linux and then shut the computer down as normal. Remove AC power and re-insert the battery. Plug AC back in and power it up, see if it does the same thing. If it does the same thing the battery is faulty. If it boots up with the battery in then there was a glitch.
Try to perform power drain. Take out the battery unplug the power adapter then press and hold the power button for 30secs. Put the battery back in then plugin in the power adapter then turn on the computer. If same issue occur, then you need to replace your battery.
Both batteries could be dead. But if you bought a new battery, it's unlikely. I don't know what green light you see, but if it's on the power adapter, it just means it's turned on--not that it is charging. Two possibilities: Your power adapter is bad or the motherboard is bad. Because you say the computer works if plugged in, then you have ruled out the adapter. You should be checking/cleaning the battery contacts and if all else fails, going for a new motherboard.
Unplug All External Devices Unplug the AC Adapter From the Wall Outlet. Disconnect the AC Adapter From the Laptop Reseated the power cable to the adapter. Remove the Battery Connect the AC Adapter Directly to a Known Good Outlet, But Not to the Computer Verify That the AC Power Adapter Has a Solid Green or Blue Light. The AC adapter status light is solid green. The AC adapter status light is solid green.Press the Power Button and Check for POST. Post means if you see the dell logo,remove the battery, plug the ac if still it wont turn on or doesnt have any light,Reseat the Memory if after reseatting the memory still the same problem it might be a bad motherboard.
