hus,

I have acer aspire 5580, problem is black screen & also external monitor is not working, cpu is working

Check memory modules. One of the modules can be bad.
You can remove memory modules one by one and test the laptop with one at a time. This way you can find the faulty memory module.

Hello i have a acer aspire 5535 laptop and its running Windows Vista Home Premium SP2 and it has 2 GB DDR2 and 250 GB HDD and i was wondering how hard it is to upgrade it to 4GB DDR2

thanks for the reply,.as u said ..for best results I would use absolutely identical modules is infact absolutely correct.,that is one must have same bus speed and capacity for dual channel to run…I hav another question,would b very appreciable if u answer,.as u said i saw on my installed memory module,it is 1GB DDR2 667 Mhz,please tell me can i use 2GB DDR2 800mhz on the other slot??..i dont know whether my motherboard supports 800mhz or not,..Is it very necessary for the motherboard to support faster bus speed if i am going to install on to it??….finally tell me if i dont put the same identical modules,i know it wont support dual channel,but if comparing 3GB ddr2 with 2 identical rams making total of 2GB 667 mhz each as u said……what will be faster,..2 gb(with dual channel support) or 3 gb ram??..thanks in advance.

faisal,

i hav acer aspire 4710G notebook,i got it with 1gb ddr2 ram installed in one slot,the other slot is empty and i want to upgrade my ram to 3gb total,by installing 2gb more on the other slot,,but i dont know the bus speed of my 1gb ram

Isn’t it written on the memory module? Does it have a sticker at all?

may be it is 533 or 667 mhz,please tell me is it neccessary to install the ram with same bus speed or can i upgrade by adding 2gb ddr2 of 800mhz bus speed?

You you have a 533MHz module installed, the second one could be 533MHz or 667MHz module. Faster modules are backward compatible with slower modules. The 677MHz module will slow down and run at 533 speed.

please tell me will it support dual channel if i add 800mhz bus speed in the other slot?

I believe for dual channel operations you must use identical memory modules in both slots and the capacity is crucial. For example, if you have a 1GB 533Mhz module in one slot, you have to use a similar 1GB 533MHz module in the second slot. If you install a 2GB module, the laptop will not run in dual channel. I guess you can use a 1GB 667Mhz module but for the best results I would use absolutely identical modules. Please correct me if I’m wrong.

Harvinder,

I have installed wifi lan card in it ( Pro/Intel 2200bg). In the device manager I can see the wifi card and also on the task bar. But it is unable to connect with Access point. I checked it with Intel utility … it is always saying that sender is not switched on….. some hardware switch is off

Do you have a Wi-Fi switch somewhere on the laptop? Maybe it’s off? Some people overlook that.

Hello ! I have one question regarding Acer Aspire 1400. I have installed wifi lan card in it ( Pro/Intel 2200bg). In the device manager I can see the wifi card and also on the task bar. But it is unable to connect with Access point. I checked it with Intel utility … it is always saying that sender is not switched on….. some hardware switch is off. Do you have some adea about that ???? Thanks in advance waiting for your reply.

Carl,
You can use two different size RAM modules. In your case, if you replace the existing 512MB module with a new 1GB module, you’ll get 1.5GB total.
But if you want to take advantage of dual channel technology (better performance), you should use two identical RAM modules.
If you want to upgrade memory in your laptop, I would recommend replacing two 512MB modules with at least two 1GB modules. In this case you’ll get 2GB total and your RAM will be working in dual channel.

Can I use different size RAM modules? For example, I have two 512MB modules installed. Can I remove one 512MB module and install a 1GB module instead? Will it work?
