Multicolored vertical bands means that the contacts on LCD ribbon cables are still shorting because of liquid or oxide building in consequence of liquid damage.

Also keyboard is probably not working for same reason.

When you get liquid damage you need to remove immediately the battery and the ac charger, and service the laptop, to prevent more damage caused by shorts.
The service is done by a technician, disassembling the laptop and using a cold hairdryer from distance to dry internal parts.

You must ensure the laptop has no liquid inside before starting it.

In your case I can only tell what parts are working:

If you can see the vertical bands and there is no static stain on display caused by liquid penetratrion, then the LCD is working.

You have backlight, therefore the inverter is working.

To connect to external monitor you can try starting the laptop with video cable already connected, It should start on ext. video.
If you are getting video signal on external monitor, that means that the motherboard is still working.

If you also get windows splash screen (or Linux) , then the hard disk is also fine.

If you do not want to spend any money for this laptop you can wait few more days, with battery out, and try starting it, in the meanwhile oxide can cause more internal damage, that is not the right way to proceed.
The laptop should be sent for repair.
If the laptop is less than one year it will still have factory warranty. However, factory warranty does not cover liquid damage.
If you do not mention that there had been liquid damage , they will probably not realize, and cover the repair, but that won't be really fair toward manufacturer.
To do things properly contact manufacturer and explain them what happened , so that you can arrange a repair, if laptop is fair new they will make an effort to keep quote low.

Do not forget to leave feedback.

SOURCE: New Compaq CQ60 615DX will not turn on

Take out the battery and also take out the memory as well. If the laptop still won't turn on, then the motherboard is bad. If the laptop gives you a beeping sound, then reseat one of the memory sticks to see if you get video. If not then try another memory stick into the other slot. If you still don't get video then you'll know for sure the motherboard is bad.

( Dell xps m1530 laptop ) Monitor blank, powers up but screen won't come on.

It ISN'T the LCD screen. Since you diagnosed with an external VGA monitor, you now know the problem is the laptop.

(When you connect an external VGA monitor to a laptop, you are bypassing the Video Cable, and LCD screen. You are connected directly to the laptop )

The basic Windows files aren't being found. The boot files. This may mean a bad Harddrive.

Do you have the Restoration CD Disk? Laptop on insert it into the optical drive tray, close the tray.
When asked choose - Repair. (Non-Destructive Installation)

If a checkdisk is done, you have bad sectors on the harddrive.
There IS a special procedure in replacing a harddrive.

Dell inspiron 1525 won't turn on

Try to take out the battery and just use the adapter to power it on,
If your done with that then try just using the battery to turn it on, if it still won't give a single light.
If you can borrow an ac adapter for that laptop try it ,
If it still doesn't work. You'll need to replace the motherboard. Just make sure the ac adapter your gonna use is working good.

Archos 404 not charging

Dont use the USB to charge the 404. Use a wall charger that accepts USB. Wally world (Walmart) has one for 15 dollars that has 2 USB ports. It works for me. Also the docking station will charge the 404 in no time at all. It's 80 dollars. Make sure you get the generation 4 unit
