Laptop will not power up


Take the battery out, plug in the charger and see if the laptop works. If it works, the battery may be the problem. Check the AC Adapter
Check to make sure the adapter is plugged securely into the wall outlet, connected firmly to the adapter box and to the back of your laptop. Most AC adapters have a little light in them on that rectangular box in the middle of the cord that lights up when it's getting electricity. If that light isn't on, try a different outlet. Check your fuse or circuit breaker box and plug a different device into that outlet to make sure there is power to it. If it still does not light up, your adapter could need replacing. Also check the adapter box for signs of warmth, as it will generate heat when it's plugged in. No heat means no power.

Remove the Battery Sometimes it's as simple as a seated battery. Remove the battery entirely and clean out any dust, lint or hair that may be clogging the connectors and preventing a proper connection. Reseat the battery securely and make sure the little locking pins that hold your battery in place are securely fastened and there is no movement. Unplug your laptop while it is running. If it still works, the battery has been charging. If it shuts off, or doesn't hold a charge very long, you have a bad battery. Unplug your laptop while it is off, then try to turn it on. If the battery is bad, your laptop probably won't turn on at all. Turn off your laptop's screen-saver when testing its battery. The screen-saver will conserve the battery and not give a clear time frame for how long your battery can really last. Click the battery icon on your laptop when it is unplugged. It can tell you how much battery life you have available. This icon is usually located in the bottom right corner of your screen and will provide the percentage of battery power you have left. Keep track of the time it takes to go from 100% charged to 1% charged. If this takes less than an hour, your battery is probably beginning to fail. You can also try this every week or two to see if your battery holds a charge for shorter periods. Factor in the amount of time you have used your laptop. Most laptop batteries last 2 to 3 years or about 500 charges. Wait a few days before determining whether a new laptop battery is faulty. New batteries sometimes take a few charges to build up to their maximum run time.

Hi
Normally the AC adaptor gets fried, the fuse inside the plug that goes into the mains normally blows. If you are getting power to the laptop in some form, you should first of all check the adapter.

Plug this into the mains and, with a multimeter set to 20 volts DC place the red probe onto the inner jack pin, and the black probe to the outer part of the jack, see if the voltage reading is 20 volts, give or take a volt. ONLY do this if you have first inspected the charger, check for any burning smell or melting of the case or wires (to be safe).

If the voltage is correct, (remember that dell laptops will only charge with genuine Dell chargers), the charger may be powering the laptop but NOT charging it..If you can, try and obtain another Dell charger to eliminate the charger being at fault.

Now remove the battery, press and hod the power button for 30 seconds and try it on ac power alone, a fried battery will sometimes stop the laptop from booting, if it DOES boot, the battery has been damaged (possibly the battery charge circuit too).

If it does NOT boot, the problem lies on the motherboard. There is, near the charger port on the motherboard a small ceramic fuse of about 3mm length with metal caps. This may look intact but if again, you apply a multimeter set to 10 Ohms across the terminals of the fuse and do not get a reading, the fuse is dead and will need replaced. I normally bridge the fuse connections with a soldered wire of 3 amps but this is NOT a recommended fix long term

If the laptop still does not boot, there is a resistor or possibly a capacitor blown, remove the motherboard fully and check , you will see a blown resistor as it will appear charred and blackened, whilst capacitors tend to burst at the top (usually).

In this case, it is probably not worth the cost of fixing.

If the laptop does boot, but does not charge even with a new charger, look at the motherboard again, near the battery I THINK there is a similar ceramic fuse for the battery charging circuit, check this also

Is there a problem with my laptop battery? I have a HP PAVILION DV9000 laptop which is nearly 6 months old and today, when I plugged it in it said "40% available, plugged in, not charging" I don't...


Mine is a Dell Laptop but I think yours has something like mine.
pull out your Hp pavilion dv9000 Battery to check its charge checker... its like a button in the battery when press will give you the amount of charge in the battery by, charge level is presented by small LED lights.
for your laptop side, default settings is very good actually, so try to revert back to default settings. Changing pavilion dv9000 Battery is expensive and I don't see any need in it, if you have been using your laptop only for 6 months.

IBM T30 - power issues


You might try cleaning the battery compartment. Makeing sure there are no damaged pins. Often times even a single messed up pin will cause this. Also this is a very good indication of adaptor failure. If you haven't allready I suggest getting another ac adapter specific to you machine. Even a substitute will casue the same issue you are now experianceing.

Toshiba Laptop wont work unless plugged in, i recently bought a new battery think that the battery was the problem and still it doesnt work unless its plugged in. please help me!


Go to CONTROL PANEL / POWER OPTIONS / POWER METER. Is the battery charged or charging?

If POWER METER says the battery is charged, you have a motherboard problem. Take it to a tech.

Do you have a voltmeter?

Remove the battery and check for voltage at the laptop's battery contacts, while it is plugged in. No voltage = charging circuit defect. A blown internal fuse or other motherboard problem. Take it to a tech.

Voltage OK or no voltmeter - take it to a tech.

A qualified technician should have a schematic and other technical documentation for your model It can be rather difficult (expensive) and hit-or-miss to locate possible fuses without the factory paperwork.

Good luck.
