MD2614U will not turn on. red light blinks three times


The first thing to do is check that the charger is putting out the correct voltage, which should be ~19 volt. Then try to start it without the battery.If your voltage is OK and the battery out makes no difference, then I would suspect that you have a motherboard problem that must be fixed. If the computer starts up if you wiggle the DC plug where it goes into the computer, then it's the DC jack that is looks and must be re-soldered.

The dead laptop charger may be another cause. Try a new and correct one:

It sounds like you have a bad battery charger, but it could also be slightly corroded battery contacts. Make sure the contacts on the battery and inside the computer are clean (you can use a qtip and alcohol, or a pencil eraser). You will have to measure or have someone measure the output of the charger, to make sure it's putting out a good charging voltage. You can use a voltmeter to do that.
If you can run it by Best Buy, they can check to see if the charger is good. There's also a possibility that the battery has gone bad, and in that case, they may not hold a charge.
Good luck, and hope this helps.

Dear Sir,

By analysing your problem it seems to be your adapter dead.So first check your adapter,so your laptop battery may not have backup to turn on the laptop.

Inspiron 1521 adapter vs battery


take an ohm meter you can buy for ten bucks at radio shack put the volt meter on DC volts plug the charger into the battery charger end the black lead goes tothe outside and the red goes inside, set the meter for 12 volts dv and mesure the voltage. read the voltage output on the battery charger transformer see if it's within a half volt if not the charger is bad, if it's ok then use rubbing achol and a q tip to clean the battery connectors on the computer and the battery itself, if you do not get the light then pull the battery out and hold the power button in the on postion and hold the enter key for 1 minute and try again, if the lights do not come back on your battery is dead, if the computer will still boot with the battery then the charger is working if it won't boot up the battery is dead. Got it?

Lenovo z51t, no indication of life when power up


Try this. Turn off unit. Unplug charger. Take out battery. Replug charger - not battery. Turn on computer. If it comes on the battery has a glitch and should recover after an hour or so. If it doesn't come on, the unit needs to see a reputable computer repairperson.

Good Luck

Toshiba satellite Dead


Try to push and hold the power button. It more than likely went into hibernation/sleep mode. If this does nothing then remove the battery and charger, then put the battery back in and plug it in and see if this does anything.
