I tried, using the AC adaptor, to turn the computer on. The green “power” light goes on and there’s a brief sound(less than 6 seconds) like that of a disk drive starting up. But that’s it. There is no screen image and no other disk drive-like sounds. I thought that it might be an auto-off due to a low battery. But, since I don’t have a screen image, I can’t tell the level of the battery. Is this a power supply issue?

Please turn off the Computer and disconnect the AC Adaptor then remove the Battery. Next, try cleaning the metal contacts on the Battery and reseating the RAM modules.Then, connect only AC Adaptor to the Computer and try to turn it ON without the Battery. If the Computer doesn't turn ON then disconnect the AC Adaptor and insert the Battery then try turning ON the Computer. If the issue persists even after performing all the above steps then service will be required.
look here the problem can be of two types,,first the problem can be of the adapter or the port in the computer where the adapter pluggs in the computer,,look for any friends or relatives using the same computer with the same good adapter,,plugg it into the computer,,if u dnt c the problem then prob with the adapter or else prob with motherboard
Hook up your power adaptor to ac power without it being hooked up to the laptop and see if the green light stays on. If it does then you know your adaptor is okay. if your adaptor is only hooked up to ac power and the green light still turns off then you know your ac adaptor is bad.
Take out the battery from your laptop. Now hook up the ac adaptor to the laptop and if it stays green then you know your battery is bad but you also want to make sure you can get your laptop to turn on. Hopefully it will turn on with only the ac adaptor hooked up to it.
Try turning on the system without the AC adaptor. If it doesn't work on battery, then try pressing and holding the power key (after removing the battery) for 30 seconds.
Now attach the AC adaptor and try to power on.
If it doesn't work, it sounds like either a motherboard issue or an AC adaptor issue (possibly there isn't enough voltage being supplied) but it's an odd problem. I hope I helped.
Stay spicy, and happy lappying! :)
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.
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.
Although symptom is showing that AC Adaptor is not working as its not providing power to the unit. I will suggest you to perform some basic troubleshooting steps. Check if outlet is working if not check with known working outlet. If you have a multimeter you can the output of the AC adaptor.
Also you can perform full power cycle and component discharge. Take the battery out and disconnect the AC adaptor press the power button and hold about 7 seconds. After that put the AC adaptor in and test again.
If issue persist take to nearest Service center check with known working AC adaptor. After that I believe you will figure out the best solution.
Look at the power indicator. If it is not lit, no power is being supplied to the computer. Check the following:
If you are using on the battery, it may be low and unable to power the computer. Connect the AC adaptor to recharge the battery pack.
Make sure that the AC adaptor is properly plugged into the computer and to the power outlet.
If it is lit, check the following:
Is a non-bootable (non-system) disk in the external USB floppy drive?
Remove or replace it with a system disk and press <Ctrl> + <Alt> +<Del> to restart the system.
The computer's power management system automatically blanks the screen to save power. Press any key to turn the display back on. If pressing a key does not turn the display back on, three things might be the cause:
The brightness level might be too low. Press <Fn> + <→> (increase) to adjust the brightness level.
The display device might be set to an external monitor. Press the display toggle hot key <Fn> + <F5> to toggle the display back to the computer.
If the Sleep indicator is lit, the computer is in Sleep mode. Press and release the power button to resume.
