Sharp M4000 fan problem

I have used my sharp M4000 for 2 years, but couple days ago the cooling fan has some irregular noise especially when it is in low speed, it seems something stuck inside to prevent it to run smoothly. Anyone know what's the problem is? thanks.

Fans will collect dust and dirt over time and should be cleaned out occasionally with compressed air.

Turned it off one night after using, turned it on the next morning and it said "operating system not found." I have had this for a very long time and it is an important part of my day. Please help


Make sure there is no disk in the dvd drive, all usb devices un-plugged and try again. If you still have the same problem then it sounds like you hard drive has crashed.

Yes it can be replaced and it has to be done with experience in soldering desoldering or the mobo will be junk. Splitting the cases is only a small part of the job if you have no experience in soldering methods. See if there is another way that you can charge the battery but I can not imagine it to be convienent

Screen getting dark on sharp pc-m4000


You most likely have a defective screen - a defective inverter or a CCFL lamp. To determine if you have a LCD screen or video card problem, read this and follow the instructions. Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case. The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills. Check out www.lcdparts.net for parts, repair service and DIY info.
