Not switching on


Hi, Disconnect your ac adaptor from the laptop and remove the battery for about 30mins. Then keep power button pressed for about 10 seconds. Now fit install the battery and the power lead, wait for the mains led to liight which should also show the battery led as being charged, after 20 seconds, power up the laptop.
It should now power up, if not check if any flashing leds are present and if the lcd screen tries to light up.

Will not boot. Make strange rhythmic noise after about 10 seconds of switching on. Almost sounds like a tune


this is from the ram memory ...a change in the hardware ( memory downgrade or upgrade) ///or just an error done this ...remove the bios battery ...and put it back after 20 seconds...this will make it boot again ..but will take you to bios to fix the data and time ...first ..
remember ...any system the will not boot to configuration screen at least ...does not see the ram memory ...and can not boot up to read devices...that's why is in the loop and does that repeating click noise....some even make a continuous beep ...like in reading device ..
if after removing battery still don't work at least to the device listing ..change the ram memory with some compatible one ....
just read the old one ...or what is written near the slot ...DDR ..or DDR2 ..or sdram dimm ...etc..and the important thing is the frequency to match

Computer is not booting properly


Unplug power from the device for 2-5 minutes, with the machine in the On position if possible, or holding the power button in for at least 20 seconds.

Once this time has elapsed, attempt to boot the system pressing F8 repeatedly while it is powering on.

If you can get to a boot menu, select Safe Mode.

Simply allow it to Boot and then select Shut Down

Boot it back, and your issues, if minor, should be resolved. Please let us know if you are still having any issues.

I am struggling to obtain a wireless connection on my laptop. Despite my wireless key being switched on the status is described as 'disconnected'. does this suggest a fault with the laptop?


Most of the problems you can solve in wireless connection by Turning off your modem and Router for 20 seconds and turn it on back again.
Hope it would help you too.

RE HP Pavillion ZE4800 Laptop When I switch on I here the fan start, the lights come on then it appears to shut down and re attempt to start again This occurs over and over and the PC never boots fully....


I have same notebook and similiar problem. Mine runs for 30 min then shuts off completely in like 20 seconds. I added a $10 usb powered laptop cooler pad and bingo, runs now for hours no problem. On all computers I know the cpu heat temperature has a threshold, if it goes too high it will shut off. I think my fan doesn't kick on fast enough to lower the temperature and cool the processor. On yours it may be a fan that doesn't work or is working at the wrong time and the circuit shuts off the system. Shouldn't be terribly expensive maybe $60 to repair from a good technician..good luck
