Hi i need help plz, i've my laptop do not power when i plug the ac adapter ther' is no ligth

Perhaps remove the multi-bay battery, and let main battery charge all the way. Then reattach multi-bay battery, and see if it's recognized.
(Will charge)

That is AC adapter (Charger) removed, then remove multi-bay battery.
Plug AC adapter back into laptop, THEN plug AC adapter into power.

[You do Not want to unplug an AC adapter from a laptop, with the AC adapter plugged into power. Could be a power surge/voltage spike. Unplug AC adapter from power, when plugging into laptop, or unplugging from laptop ]

Main battery charged, unplug power to AC adapter, unplug AC adapter from laptop. Plug multi-bay battery in, then AC adapter.
(Then plug AC adapter into power)

Here below are possible causes and troubleshooting steps of laptop that can't power on, hope it may help:
Possible causes:

1. AC adapter failure.
2. Power jack failure.
3. Motherboard failure.

Possible troubleshooting steps and repair solutions:
1. Test the AC adapter with a digital multimeter. It's possible that you have a failed AC adapter. If you don't have a multimeter, test your laptop with another known good AC adapter.

2.It's possible that power jack (socket where you plug the AC adapter) is broken. Remove the motherboard and take a closer look at the power jack. In some cases you can fix the jack by resoldering it on the motherboard. In other cases you have to replace the jack with a new one. Using a multimeter, test if the power goes to the motherboard through the jack.

3. If replacing the AC power adapter and jack on the motherboard doesn't help, most likely you have a bad motherboard. Replace the motherboard.

Hi There,
If you've got a multimeter - test your AC adapter to see if it is outputting the correct voltage for your laptop. If it is, Then you've got an HP boat anchor. Unfortunately HP laptops are known for their overheating issues, and if this is the case, a lawsuit filed against said manufacturer means you may be able to be compensated for your loss.

Try this:

Reset the AC adapter by following steps below.

1. Unplug the Wii AC adapter at both ends (from the back of the
Wii system and from the wall outlet or power strip).

2. After you've waited a full 2 minutes, plug the AC adapter back in on both ends and check to see if the power light comes on.Reset the AC adapter by following steps below.

I fix these laptops as a side business and sell refurbished ones on ebay...I've seen the problem you describe but I'd need to know more about how fast they are blinking, etc. When all the lights flash about 2-3 times per second, I've found it to be a motherboard issue normally caused by a faulty power jack. That can be fixed but it means disassembling the complete laptop down to the motherboard and either re-soldering or replacing the jack. If you have access to a charged battery, disconnect the AC adapter and try to get it to boot cleanly from the battery. This will tell you if the problem is at the jack or someplace else. Post your results and we'll go from here.

Computer does not boot upThe problem maybe the RAM, it is faulty or just needsreseating to make proper electrical contact.
Reseat the RAM and then boot up your laptop. If it still does not boot up thenremove the RAM module/s and take them to your friendly computer repair shop andget them to test the RAM for you.

You've to replace the ac adapter, if it's brick doesn't get warm or LED does not glow on Power Jack on the laptop. offcourse, check with the wall different sockets

power jack can also be loose. so jiggle the cable to find out.

if notebook is getting power, you can remove the battery, ac adapter, hold and keeep pressing poer button for a minute, then, turn it on.

finally, you can take out hdd and ram, put them back again and turn on the laptop. hope it will help

You say it isn't charging, but will it run off of AC power? If it isn't getting *ANY* AC power, then it might be the female end of the power jack on the laptop. If it will run on AC, the culprit is likely to be a battery that needs replaced.

Hi there! There are two possible causes of the problem - it's either your battery or your AC Adapter. To diagnose whether or not it is your AC Adapter, test it this way. Does your laptop function with the power cord plugged in and the battery out? If this is the case, your AC adapter is fine and your battery is done. To replace the battery, expect somewhere between $75-$175. Here is a link to the cheapest battery site I've found so far - I use it for work all the time. http://www.batterydepot.com/mfg/TOSHIBA/LAPTOP-BATTERIES
If your laptop doesn't work with just the AC adapter plugged in, then that is your problem! AC Adapters are cheaper than the batteries. They can be purchased here for around $50: http://www.buylaptopadapter.com/toshiba-adapters.html
Make sure you match the model number on the bottom of your laptop perfectly with the model number of the battery or AC Adapter! Good luck! Alex

Is the AC Power adapter the original adapter of the laptop? If it is, try to drain the battery and charge it for 8-12 hours without using or opening the laptop just charge it. After charging, remove the power adapter as you open your laptop. Make this way a habbit of using and charging your laptop to make the charging and battery life last long.
