    Hi, did you hold down the "f8" key at startup to see if you can run "safemode"? If not and you can't open bios setup maybe the hard drive is bad.

You don't mention any beeping on boot... see if any of these apply.

There are a number of beep codes you may experience:

No beep at all - this means your motherboard is dead, either due to a defective or underpowered power supply, poorly seated CPU or RAM, or a dead-on-arrival board
One beep - board is working fine
One long beep then machine shuts down - faulty, improperly installed or missing CPU
1 short(Beep) System booting is normally
2 short(Beep) CMOS setting error
1 long - 1 short(Beep) DRAM ERROR
1 long - 2 short(Beep) Display card or monitor connected error
1 long - 3 short(Beep) Keyboard Error
1 long - 9 short(Beep) ROM Error
Long(Beep) continuous DRAM hasn't inset correctly.
Short(Beep) continuous POWER supply has problem
A two-tone siren, generally caused by overheating or out of specification voltages.
Four beeps then machine shuts down. This is because these version of the BIOS will shut down your machine if no fan tachometer signal is detected on the fan header. Make sure you attach a fan to the FAN1 or FAN4 header.

You can hit the F2 button, F10, F12 or Delete button when it boots up and it will go into the bios.

Compaq Presario CQ50-103NR Notebook PC stuck in sleep mode


Try and perform a Hard Reset onto your laptop.

Performing Hard Reset
1. Turn off PC
2. Unplug both battery and ac adapter
3. Hold Down on the power button for 30 seconds
4. Plug everything back in and turn it on.

When you are back at your desktop screen, change the sleep mode and display settings to 1 minute to see if you can wake it back up.
If not, then load into your BIOS by pressing F10 during boot up. Once in BIOS, press the F9 key and select "load defaults". Once you load defaults, press to F10 key again to save changes and exit. After that, search the hp website using your product # on your laptop to see if there are any BIOS updated for your product.

Power up the external monitor first and then boot up the laptop, the video info will automatically divert to the external monitor.
If you do not see a Windows image on the external monitor then it is definitely a motherboard issue, because the video card is built in on the motherboard.
The Video card uses shared RAM (part of the RAM module/s ), try re-seating the RAM modules, also test the RAM modules.
You can test the hard drive by removing the hard drive and connecting it to an USB hard drive adapter, then connect the adapter into a working computer's USB port. If the hard drive is OK, this computer will see it as an external storage device and you can open the various folders and files on the hard drive.

FS050UA , COMPAQ PRESARIO NOTEBOOK PC CQ50-210US the screen has lines and a black spot


Hi,
Turn on the notebook and press F10 to get into BIOS screen. Even if the lines and the black spot appears then the issue is with the internal hardware of the notebook.
To check further connect an external monitor to the notebook and press Fn and F4 keys on the keyboard to get the display on external monitor. If the external monitor display is fine then the issue is with the LCD screen or else the issue is with the Video card of the notebook.

The issue might be with the hard drive. I recommend you to test the hard drive.
If the hard drive test fails, then it is confirmed that the issue is with the hard drive of your notebook.

Not booting up; stopping at white Compaq screen


Take out the hard drive. Then turn the notebook back on and see if it goes past the Compaq screen. If it does then you know your hard drive is bad and it would have to be replaced. It could be shorting out the motherboard.
