The 2145US is a problematic model. It has frequent problems with overheating, which leads to electromigration. Your best bet is going to be to set up box fans around it or put it in a freezing cold room and dress warm. If you're good with computers, try putting a peltier cooler in the case and a heat sink on the exposed ATI chip.

I bought samsung mini laptop but the problem is its not booting operating sytem and im having problem reload it


Does it have a cd / dvd ?

Restart your computer during the boot process you will see on the screen to press a certain key to enter setup usually the delete or F2 key

Press and hold that key during the boot up process to enter BIOS then using the arrow keys scroll down to advanced bios features press enter change your first boot device to cd press escape then press f10 to save to cmos to restart

Note this will erase you operating system you will have to have an operating system disk to load it onto you hard drive or create a partition to load another operating system

Note after you have loaded the operating system you should go back and change the first boot device to failsafe or optimised defaults
after windows has loaded

your computer will automatically restart it might restart 2 times one to finish the installation
the next will be because the operating system is loaded and will boot from your cd

Hope this helps.

What function key gives entry to cmos


BIOS is fixed program that starts up the computer. BIOS is initialized during start up of HP Compaq-6715B which sets the computer settings to be uploaded. BIOS enables the creation of a bootable diskette, CD, or USB key that can be used to locally restore or upgrade the System BIOS in the supported notebook models with a 68YTT Family ROM. Only insert the USB drive that will be used to format and create bootable BIOS upgraded USB media. However, you should remove all unused USB drives and flash drives from the notebook before. In order to ROM family and ROM date, press F10 on the target notebook during startup to run the setup utility.

The tips to get into the BIOS of HP Compaq-6715b are:

  • Press F2 for setup
  • Shows logo
  • Independent of OS
Press F2 for setup

BIOS often has a blue background, and uses the arrow keys, PageUp, PageDown and enter keys to change the settings. After you have got into or accessed the BIOS, you can change the boot order settings so that the floppy disk is checked first to see if it contains a bootable program. Usually a message will appear telling you how to enter the BIOS setup program as the computer starts up, such as Press F2 for Setup.
Shows logo

Your HP Compaq-6715b might be configured to show your computer's logo instead of important BIOS messages. In this case, you can press Esc or Tab while the logo screen is visible. If you are facing problems pressing the pause button in time, turn on your computer with your keyboard unplugged. In this situation you will receive a keyboard error, which helps you in pausing the startup process long enough for you to see the keys necessary to enter BIOS.
Independent of OS

The PCs with both PS/2 and USB connections are configured to only allow USB input after the POST. If you are using a USB keyboard, it could be impossible to access BIOS. You would need to connect an older PS/2 keyboard to your PC to access BIOS. The BIOS accessing is independent of any Operating System on your computer because the BIOS is part of your motherboard hardware.

Will not boot up


Is your laptop switching on? Does it show the BIOS sequence at the beginning? When the Hard drive of your Laptop stops working it won't boot up. Sometimes virus also cause this problem or your bios needs resetting. Now if you decide to fix this you have to go through a number of steps to make sure what the problem is. when your Notebook loads up it shows you a number of operations that you can take like F2 or F8 or Del to enter into you Bios set up or OS start up choice. Now when you press dell you will go to the BIOS set up screen. Which will show you if your HDD is being recognized and also it's size. If all this shows well then your Hard drive is ok. So you go on to check if the operating system shows. If all is well then you might have to reload your Operating system.

I bought a new hard disk for my vgn-nr120e because the old one was corrupted and im trying to install it but my comp is just displaying an all black screen(it appears to be off) but the led light is on and...


Since you say, you have a new hard disk I am assuming you have not formatted it or there is an operation system on it. If that is the case, power on your laptop. As soon as you does this start pressing F2 (intermittently = press, then release) and keep on doing it till you get into the bios screen. Once you are there change the boot sequence to CD drive first (It will be on Harddisk at present) Once you have made the first boot device to CD drive, open the CD drive and put an operating system CD like XP, Vista or Windows 7. Save and exit from the bios screen. Restart the computer. It will say press any key to boot from CD drive. Press any key. The system will come to the operating system installation screen. Install the operating system. If in doubt get assistance in getting someone to install the operating system. Without the operating sytem or a bootable CD once the Bios hands it over to the system there is nothing to display and you do not see anything on the screen. It looks like that is your problem. Good luck.

Compaq presario 2199us notebook does not boot


Hi Krishna. Could be that the processor's cooling fan is no longer functioning and then the processor instantly overheats and everything STOPS !!! Could be the RAM memory chips not in good state anymore .....Could be that (while it tries to determine what hard drive is in there) the hard drive is BAD and cannot be identified... that would also just STOP everything. It really is quite a few things that could cause that
