You may have to perform a hard reset.
Google this for your model. Usually you take the battery out, hold the power button for 30 seconds then replace the battery.

My Toshiba Satellite A105-S2031 laptop won.t boot up. When I turn on the laptop the two small lights below F 10 and F 11 light off then the computer turns off.


Try removing the battery (in case it's shorted), plug in the power adapter and boot to bios (using F2, F10, etc). Be sure there are no USB memory sticks connected, etc. If you are able to boot to bios, great! Then, it's a matter of eliminating the root cause: either battery or hard drive. If you don't boot to bios, then you're most likely facing a hardware problem. It may be as simple as an unplugged cable.
If you can't boot to bios, consider connecting an external monitor to rule out LCD display problems.

Acer 5733z-4633 is stuck in a sort of boot loop. Won't enter bois setup or boot device options screen. Is this a hard drive issue?(it kinda makes a funny clicking noise then starts all over to try


Yes! it does sound like the hard drive is bad, remove hardware to see if you can enter bios and boot device, if yes the hard drive needs to be replaced, if no change there is a secondary problem.

Garmin 1340T boot loop issue. The unit


Hi,

Unfortunately, there isn't an easy solution for the Nuvi owner as it requires a custom piece of firmware to flash the unit to make it at least boot. This problem is often caused during a failed firmware and/or map update.

It sounds like a file was corrupted. Sometimes it is better to connect the unit up to a PC, delete the old map and then proceed to install the new one. There are so many issues with memory space causing failed downloads and corrupted files.

If the map file is missing, the unit will boot-up OK, it will just say "Map data unavailable" but if the map file or associated map files are corrupted, it can cause the unit to crash. Your PC won't recognize the Nuvi because you have the reach the main screen before the data communication mode routines are accessed.

We've had some success in restoring some of these units by flashing a "fix" firmware in "pre-boot mode" that doesn't try to load the map or map associated files. This should then allow the unit to boot. Once the unit boots, Windows will recognize it and then you can copy a map over to it from the PC. Reboot the unit and then flash it with the standard firmware.

Hello I have a hp pavilion p6000 series,and everytimei try turning it on it won't boot up the monitor?


If the monitor is not booting up than may be there is display problem on the mother board. Replace the CMOS battery of the motherboard and then check. If this solution not work then there is technical problem in the motherboard which will get fixed only by expert motherboard repair technician.

Try to light the display with a use of flashlight, if you see a deemed display in your LCD monitor it means the inverter of your monitor have a problem try to check the Inverter circuit in your board or try to press camlock key on your keyboard, if the light goes on and off it means your motherboard is booting normally.

My Computer system clock (time) is in a loop, between 12:00hrs and 14:00hrs (Date will not change). I have tried to change the settings in BIOS and also restored the system to a date before the problem...


Hi mutumbac. Please check the battery on your computer's motherboard. All motherboards have a small (clock-type) battery that powers the internal clock even when the computer is turned off. These batteries are good for about 2 years, and after that they should be replaced or else the computer will reset the date and time every time it boots up.
