My remote speaker system works with the batteries but not with the AC adaptor plugged in to the speaker.

test the battery with multimer for to see is o.k with the voltage. measure. Otherwise you can put the package with plastic bag(windzip) and put by 24 hours in the freezer from your refrigerator for to revival of your battery. and try again in your radio. ( this is smal secret for revival battery rechargeable.

God bless you

You could try another battery.But if another battery doesn't work,sorry mate I think it's dead.In future make sure you only use what you know is compatible,also NEVER try to run the PSP with the AC adaptor without the battery in.The PSP safety and support booklet states: Do not use the PSP system with the AC Adaptor when the Battery Pack is not inserted in the system.If the AC Adaptor is disconnected suddenly,it may result in damage to the system.

If it is the motherboard that's burnt out I think you can replace it but they're expensive I think,I saw one for a PSP1000 for

Remove the battery and plug the ac adaptor in check wethere the light on the port where you connect the ac adaptor glows or not, if no then check the wethere the ac adaptor is getting warm or not after you plug it in for few minutes if not then ac adaptor has to be replaced.
If the light on the port is glowing then it is likely that the power supply of the notebook has gone bad as it is not able to switch to ac adaptor or the port where you connect the ac adaptor to the notebook has a short circut when the acadaptor pin is connected , better try with a different ac adaptor to be sure wethere the issue is with ac adaptor or the notebook.
My best wishes

It could be an AC adaptor issue.

It should boot when connected directly to the power outlet through the laptop adaptor. If it is not boot, then the adaptor might not be supplying the needed power to boot it up.

If it is possible, try to isolate the issue. Charge your new battery using another laptop. Then plug it in your laptop to see if it works. If it will work, then it is the AC adaptor of your laptop that is defective. If the charged battery still won't make the laptop boot, then there is something wrong with your laptop hardware. If could be a motherboard issue of your laptop.

Press the RESET button on the rear of the unit while it's turned on. After that unplug the AC adaptor and wait a while before plugging it again.

Did the speakers come with the computer? If so they likely  have the amplifier section built into the computer, ergo wil not work on a different brand/ model computer.

FIRST REPLACE YOUR BATTERY, THEN ALSO CHECK VIRUS WITH AN UPDATED VIRUS CLEANER.

Hi! TRY THESE TO SEE IF WE CAN GET YOU POWERED UP! :)



Confirm the system is not in HOLD mode
Make sure the PSP system is not in Hold Mode (in the down position). Slide the Power/Hold switch up to clear Hold Mode. Or try sliding the Power/Hold switch up and holding it there until the power indicator light turns off and the PSP system is completely turned off. Then try turning the PSP on again.

• Confirm the backlight is ON
  Make sure the LCD screen's backlight is not turned off. If it is, press any button to turn ON the backlight.
  
  
• Confirm use of only licensed products (AC Adaptor, battery pack and charger)
  The AC Adaptor, battery pack and battery charger must be licensed for use with the PSP system. All licensed products for use with the PSP will have the following logos displayed directly on the product and/or the packaging:
  
  If any of the products you are using does not have these logos on them, we recommend that you immediately discontinue the use of these products, as they void the PSP system's warranty, and can cause damage to the system. See compatible peripherals for the PSP system for a full list of supported products.
  There are some products that can be used with the PSP system that may not display our logos. Products such as San Disk 1GB Memory Sticks, or various USB cables, needs only to be genuinely certified. Look for the genuine certified logos on these products or contact the company which manufactures these products for more information.
  
  
• Confirm the battery pack is correctly inserted
  Make sure the battery pack is in its proper position (see inserting the battery pack for details).
  
  
• Try the battery pack only
  Unplug the AC adaptor from the PSP system. Make sure a charged PSP battery pack is inserted inside the PSP system. Turn on the unit. If you get power, then the problem may be with the AC adaptor and power cord.
  
  
• Try the battery pack in a different PSP system
  If possible, try your PSP battery pack in a different PSP system. If your battery works on a different PSP system, it may indicate an issue with your PSP system.
  
  
• Try a different PSP battery pack
  If possible, try a different battery in your PSP system. If a different battery pack does work on your PSP system, it may indicate an issue with the original battery pack.
  
  
• Try the AC adaptor and the PSP battery pack
  Insert the battery pack and plug in the AC adaptor. If you still do not get any power, your PSP system may need to be sent in for service (see PSP Service for details).
  
  
• Try the AC adaptor / power cord only
  Turn off the PSP system, unplug the AC adaptor, and remove the battery. Now plug in the AC adaptor to the PSP system with the battery removed. Confirm the AC adaptor and power cord are firmly connected to each other. Now make sure they are also firmly connected to the PSP system and the electrical outlet.
  If the PSP system powers on, the battery may need to be replaced.
  
  
• Check AC adaptor and power cord for damage
  Visually inspect the AC adaptor and the power cord for damage. Do not use if frayed, cut, or damaged in any way.
  
  
• Check the electrical outlet
  Confirm the electrical outlet that you are using is active (receiving power). Try using a different electrical outlet.
  
  
• Try a different AC adaptor and power cord
  If possible, try a different AC adaptor and power cord. If a different AC adaptor and power cord does not work, the PSP system may need to be sent in for service (see PSP Service for details).
  
  
• Confirm no unauthorized system software or downloads were used
  Confirm that you have not used any unauthorized system software updates or downloads on the PSP system. Use of such unauthorized firmware updates voids the warranty and can damage the PSP system.
  
  
• WLAN turned off
  Make sure the wireless (WLAN) network function is not in use while charging. The battery pack cannot be recharged when the WLAN function is being used.
  
  
• Power surge
  If you experienced a power surge, shortage, or a lightning storm in your geographical area recently, this may have affected the PSP system's power supply. Please contact Consumer Services below for information.

The blinking orange battery light generally indicates that the battery isn't working properly, usually going out and not charging properly. In this case, since the adapter will not power the machine without the battery, and it should, I'm going to say that the adapter is going out and not getting the proper amount of power to the system. Try replacing the adapter. Be sure to replace it with a Dell replacement, the Targus brand universal adapters do not work well with Dell machines, and in most cases won't work at all.

there is a switch in the plug end to the back of your comp its like a little swinging door that when you unplug out of back of comp this switch engages battery now if you unplug just from wall its going to see these 2 things the doors not shut but i have to keep working so it sets aside the plug still recognizing it of course but running off the battery trying to still find out why the powers not there but the plug is still plugged in and it will continually search until it reaches its falt point of dead battery
its like a battery backup for your system it gets unplug but wants to know where the power is

now in reference to the little swinging door i call it its a power over relay in your comp for some reason its not closing properly to allow battery to run by self
this is usually just a switch that needs adjusted in the motherboard configuration
