Shut down, unplug, remove battery, plug in, reboot. If it reboots, open Control Panel, Power Options, Advanced power settings, Change Sleep and Hibernate to Never. Adjust the settings to your preference. Set the Screen Saver time. When your laptop is not in use shut it down and unplug, this will prolong life and a reboot everyday will reset your laptop.

Try starting it with just the adaptor or just the battery.
If the adaptor is broken it might not properly power-up, same goes for the battery. You'll need to exclude these two first.

If it starts with just the adaptor: dead battery.
If it starts with just the battery: defective adaptor (broken connections, insufficient power etc.)

In both cases you should probably call upon your warranty. That is, it that is still applicable.

If both situations don't work, let me know and we'll think further.

Greetings,

DarkNeogen.

My hppavilion f1503 flat panel lcd monitor screen stay blank


The monitor should be plug and play, and you've already figured out that it's not your computer by plugging into a working monitor.

This is most likely the power inverter board in the monitor - this is common in many monitors. If the power light is blinking on-and-off, or just staying on with no image, that's the problem. There is a slight chance that it could be the light itself, but inverters fail more commonly.

If it's under warranty, send it back, if not, there are inverter boards for many common models of LCD monitors that are replaceable. The board can run anywhere from $50 on up. Depending on how old it is, you may find it better to just replace it with a gently used one from ebay.
