Sir, i have two old laptop's one is hp 630 with i3-380m and another one is acer aspire e1531-B962G32Mnks with dual core processor. Acer one's display was broken so i changed it with hp one. Because the connectors are same. My question is this will work or not ? Another thing is can we run the laptop and display will get turned on or not without the hardisk? Lastly, when i turn on the acer one with it's own processor it turns on and turns off. I changed it with i3 as the sockets are same 988A. It turns on but no display. What is the reason behind it? Hp motherboard has one resistor broken in it can it be replaced with another or repaired ?

Hi my Friend I have a computer Acer model # Veriton Z291G, my problem started when the screen start to flickering and now is not showing nothing the screen is black, when I turn on the computer the only thing I can see for few seconds is the brand of the computer and the windows 10 logo and that set no more the screen goes black at this point I don't even know if the computer is not starting up the operating system or the video card is gone or the LCD is bad, also there is no way for me to add an external monitor There is no plug, how can I check first if is the LCD or the video card so I can proceed with the operating system, any ideas? than you so much.
Check keyboard num lock led on/off while it press .. if yes that means your computer was working but lcd screen doesn't appear any image or dim light image .... In this case need led change if there is lcd screen then inverter circuit bad or lcd ccfl bulb was bad

sir 1 question my laptop is toshibha 15.5" 720p display , C665 if i buy FULL HD 15.5" screen with same 40pin connector ? will it support full hd ? chipset intel hm55
i dnt know partno: because i haven't purchased full hd screen because i am not sure Sir in desktop if we change monitor , mother board will automatically support new high resolution monitor and its resolution what about in laptop ? is it same principle ?
desktop monitor work on analog signal of RGB,H/V and vga port out 50hz to 85 hz frequency . so if monitor support those resolution .. but lcd screen work on digital signal .so hd signal is different then normal lcd signal .. (it's work on resolution) .so there is no same principle about vga and lcd output..
