I had a a/c power problem with the jack and fixed that.
now when i power up, the a/c plug in light on the front flashes on and off for about 1/2 minite then shuts off and the computer is not detecting that the power supply is plugged in?
I think a transistor may be going bad....and circuit information out there?
and what does the flashing indicator mean?

Sounds like your DC Power Jack is bad or broken. The DC Power Jack is where the power cord plugs into the laptop? Most times it get damaged by too much stress on it such as sitting in bed with the laptop, or putting the laptop in the laptop bag with the power cord still plugged in.
Take an ink pen and put it into where the Power Cord normally plugs into the laptop. If the pin inside the DC Jack is loose or wiggles then the jack is probably bad. Sometimes the jack can be completely burned out and you can smell smoke .
If the internal DC Power Jack is loose, you will have totake the laptop apart to repair it. The DC Power Jack is on themotherboard and most times it is soldered to the motherboard. That meansyou will have to desolder the old one and solder a new one in it's place. Sometimes the dc power jack sits in a slot between the bottom case and palmrestwhich hold it in place and has a cable harness that plugs into the motherboard.
Check the charger is throwing out the correct voltage at the DC jack Do you get any lights flashing at the charger? If you do it indicates that power is not completing the circuit and is being "spat back". This would indicate a damaged charging circuit or possibly a loose power jack socket, if it feels loose as you plug it in, you may need to change the DC socket
Typically that flashing light means low battery. Which makes sense, as you probably have an issue with the AC Adapter that you plug into the computer to charge it, or the DC Jack that this adapter plugs into on the laptop. Either of these things will cause your computer to not charge the battery, and if there isn't enough power it won't turn on.
F then 2 flashes when in: Diagnostics Test mode if a stuck key is detected. Standby mode if there is a user interface mismatch. DISPLAY (Saved Code) EXPLANATION AND RECOMMENDED PROCEDURE
Console and Indicators This test is performed when any of the following situations occurs during the Console and Indicators Diagnostic Test:
None of the indicators light up No beep sound is heard Some buttons do not light indicators None of the indicators light up: 1. Perform steps in Accessing & Removing the Electronic Assemblies, and visually check that the P11 connector is inserted all the way into the machine/motor control. 2. Visually check that the user interface assembly is properly inserted in the console assembly 3. If both visual checks pass, replace the user interface assembly. 4. Plug in washer or reconnect power. 5. Activate the Console and Indicators Diagnostic Test mode to verify repair. 6. If indicators still do not light, the machine/ motor control has failed: Unplug washer or disconnect power. Replace the machine/motor control assembly. Plug in washer or reconnect power. Activate the Console and Indicators Diagnostic Test mode to verify repair.
No beep sound is heard: 1. Perform steps in Accessing & Removing the Electronic Assemblies, and visually check that the P5 connector is inserted all the way into the machine/motor control. If visual check passes, replace the user interface assembly. 2. Plug in washer or reconnect power. 3. Activate the Console and Indicators Diagnostic Test mode to verify repair. 4. If replacing the user interface assembly failed: Unplug washer or disconnect power. Replace the machine/motor control assembly. Plug in washer or reconnect power. Activate the Console and Indicators Diagnostic Test mode to verify repair.

Tv turn on?Front LCD panel LED power light indication flashing?Yes,than the power supply board is dead,that the board where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.
You should have a light on the notebook indicating that the power supply is plugged in (this should come on with or without the laptop being turned on). My acer has a green light for power, and the battery indicator shows amber for charging and green for full. If you are not seeing the power or charging indicators, you either have a damaged power jack, or a damaged power supply. Power supplies can be purchased usually for fairly cheap online, but if your power jack is damaged, the laptop will have to be serviced by a service center, or by someone who is skilled with a soldering iron and the disassembly and reassembly of laptops.
It might be an issue with the adapter, the battery or the AC jack on the motherboard. First up see if your AC adapter's power LED comes on when plugged into a power source. If it does, then check if the Lights at the front of the laptop indicate that the adpater is plugged in. If they light up then it means that the laptop's battery is faulty and needs to be replaced. If the lights dont light up then it means that the AC adapter jack on the laptop has bad solder joints and/or damaged. It is located at the underside of the motherboard where the AC adapter is plugged in. You will need to take the laptop apart and re-solder/replace the jack.
If you are not getting any power indication lights on the front of the laptop with the AC adapter plugged in, then you most likely have a faulty DC jack. Luckily, that sort of issue can be fixed, and it is not TOO expensive. Our company typically does DC jack repairs for about $100.
check and see if the jack where you plug the ac adapter into the laptop feels loose at all or if adjusting it slightly makes the lights flash. if you you have a loose dc jack and will need to see about getting it repaired.
