Horizontal streaks cover the whole screen...Dell Inspiron 1545.. can't shut down so force power off...then have trouble restarting.

Press and hold the power button. It sill shut down completely. If this fails, just remove the battery.

its shutting down or get freezing? meant the display get freezed and nothng works?

your guy's answers suck... i have a clean install inspiron 6400 that does the same thing with win 7 or 10, but the whole net seems to be making shiz up to try and give an answer to something they arent even familiar with, sucks sorting thru this shiz havent found a cause yet, only a million know it alls

Force off by pressing the power button for 10 seconds or more. Boot into safe mode, type msconfig in the run line, disable everything that starts. Restart normally, re-enable each program untill you find the one giving trouble.

Hold down the power button for 10 seconds. That will hard-shut the PC. Once that is done, fire it back up, and try again. Somethimes, windows will act goofy shutting down. Especially Vista when it is left on too long without shutting it down.

I would need more information than that to give you a solution. Are there any dialog boxes that pop up when you try to shut down the laptop? What operating system are you running? Are you experiencing any other problem with the laptop (multiple problems are related more often than you might think).

try this
remover battery
disconnect power supply
press & hold power button 60 seconds, then release
replace battery & power supply
restart

There is an spot under the computer that you can open to access the memory ram, once there just remove them and put them back in..try that

Check your computer bios settings. There is a power managment section. Turn off power managment or set it to os controled. Check dells support site for any acpi drivers that you may need. These are needed for suspending controls.

Hope this helps.

Not that I've ever heard of, Usually that kind of issue is caused by blunt force trauma to the lid of your laptop......
