Loosing CMOS setup because integrated Lithium battery is low. Replacing the battery will resolve the issue. You need to open the casing in order to reach the CMOS battery. You can also ask assistance of a qualified hands on technician for the replacement of the battery. Freezing also most likely a related issue due to BIOS settings.

Good Luck

Laptop wont start



This issue is often caused by either an incorrect setting in CMOS Setup or a bad boot device, such as a bad hard disk drive.

  1. Verify your boot options are properly set in CMOS setup. I recommend having the CD or disc drive as your first boot device and then hard drive as the second boot device.
  2. If your CMOS Setup has an option to boot from the LAN disable this option.
  3. If you have changed any CMOS settings, make sure to save and reboot the computer.

If this does not resolve the issue, try resetting the CMOS values to the default settings, save and exit.
If this fixes the problem but it reoccurs again later you main need a new cmos battery. Or keep your battery always slightly charged.

As i turned on the monitor the screen shows CMOS WRONG PRESS F1 TO SETUP PRESS F2 TO LAOD DEFAULT VALUE


hi,
first of all check the main battery back of ur machine by unplugging from the mains power supply. if machine shuts off, then u have to replace the battery.and then set the date time etc by pressing F1. and then save it and exit set up. next it will not ask for F1 or F2.

if the main back up battery is ok, then another possibility is the CMOS backup battery of ur machine have some problem. that's why it loosed all the seted parameters. then u have to replace the CMOS battery of ur machine. normally 3V battery. then set the date time etc by pressing F1. and then save it and exit set up. next it will not ask for F1 or F2.
ok

How To Fix This Error

Error Message:
Stop Error 0x0000007A (Kernel data inpage error) Translation:
This occurs due to a memory error from a faulty hardware device or virus. Solution:
If your system freezes during Operating System installation, make a note where the installation stopped. Often, you can narrow down your problem by knowing when the freeze occurs.

Frequently, installation freezes are caused by incorrect settings in the CMOS (complimentary metal-oxide semiconductor). The CMOS stores special configuration settings for your computer’s hardware and is used by the BIOS (Basic Input/Output System) when your machine boots. Your motherboard or system should have come with a manual that describes the CMOS settings. If you don’t have a manual, download one from your manufacturer’s Web page. To change the CMOS settings, press the keys as shown in your manual or on your PC’s startup screen (often DELETE, ESC, CTRL-ESC, or CTRL-ALT-ESC) immediately after you boot your computer. If you change any of the CMOS settings, write down your changes and keep them in a safe place. Then you can refer to the settings if you need to change them back or redo them if you reinstall or upgrade to a new version of Windows later on.

Incorrect CMOS settings for system cache memory and RAM may confuse the Windows installer and freeze the system. If your system freezes during setup, try disabling the system cache memory. If you are able to install the system after your CMOS changes, then you fixed the problem. If this doesn’t work, then try adding a wait state to (or slowing down the timing on) your RAM. (Wait states are periods where the CPU pauses while waiting for data from slower components.) Adding a wait state causes the computer to address the memory less quickly and often fixes unexpected freezing problems, black screens, or unprovoked reboots. After Windows is fully installed, use the new system for a while to make sure it is stable. Then, restart the system and change the CMOS settings back. If the system remains stable, keep the settings; otherwise return to the stable settings permanently.

Bad RAM chips or a boot sector virus can cause inexplicable freezes during installation. If you suspect your memory might be the trouble and you have extra RAM chips around, try the installation with the other chips instead. If you think you have a boot sector virus on your hard drive, then use a bootable CD-ROM or diskette to check and clean your hard drive using programs such as Norton AntiVirus (http://www.symantec.com) or McAfee VirusScan (http://www.mcafee.com).

The emachine model KAWE0 is with operating system windows xp sp1 doesnot recognise any usb device.


Good day sir, hi, usually its one or two ports that does not recorgnise a usb device, but if all ports does not recognise the usb device, check the CMOS setup. check this out;
  • one or two ports does not recognise the usb device, this is a local fault, try to check the CMOS setup, this could also be the port itself is the faulty one having loose connection.
  • all ports does not recognise the usb device, this is a system fault, check again the CMOS setup if the USB port is enabled, check the USB device itself also. to make sure use another pc to test the usb device.
A computer virus can also cause the usb port to malfunction, run an anti virus software, if possible you can reinstall the XP and test the USB port afterward.

If all else fails, you can buy a USB card and plug it on the expansion slot on your PC.
