If something HASN'T died, you can unplug the power and remove the battery. Plug it all back in 10 seconds later, and it should boot as normal.

My compaq f700 laptop won't boot up


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 compaq f700 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.

My laptop will not power on. It is plugged into the charger and the blur light on the cord is on but it will not turn on.


Turn on your laptop using battery, if it's working remove the battery and plug the power adapter then turn it on. If nothing happened that means your battery is in good condition but one of the reasons are your motherboard chipset fail or your power adapter fail. You can check your power adapter with your friends having the same model laptop to determine what is really not functioning. If your power adapter are working, so you have the options. One is to replace your motherboard or buy a new laptop. Have a good day!

Acer Extensa 5620: The power supply jack is loose when you plug it into the laptop. Sometimes it will provide power and sometimes it will not (orange battery light on front of laptop goes on & off)....


System check
1. estimate the extent of damage, possibly requires entire board replacement housing the extension power supply modulators, possibly due to physical damage on contact.
2. Aslo check the battery life since could determine the possibilty of substituting power chord from currrent outlets with batteries

The device would not connect to power outlet without a properly functioning battery installed. A depleted battery could not be replaceble by connecting a source out power outlet. each parts of the power complement the entire process of achieving computer experiece.

Consult a technician insisting the replace the entire power system of battery and ac adapters and also fixing damages on the mother board may be contributing to power leakage

Laptop won't dock


The inspiron 600M will not function in a D-Dock, but will work in a D-Series port Replicator. (Although the D600 and 600M share the same motherboard, the bottom plastics are different)

After trying the 600M in the D-Dock, it is possible the dock is damaged. I would undock the D630, then delete the docked profile. power off, dock, and reboot and see if it detects and works.

Was the laptop on when it turned off? It may be a PSU problem but we can determine this by removing the battery. Make sure you disconnect the AC adapter while your removing the battery. Inspect the contacts and make sure`there are no black marks or any other dirt. Leave the battery out and plug in your AC adapter. Try the power again. 
There are a couple of possibilities in terms of problems that I can suspect so far. Did anything out of the ordinary happen when the computer just stopped working all of the sudden.
1. Battery has failed and short circuited the contacts 2. Power supply failure 3. Motherboard could have failed in style. 4. Power contacts for the AC adapter are damaged.
