Question about Acer Aspire 5100 Notebook

1 Answer

Possible ram/mbo failure... notebook unusable

My 5110 is 2 years old, and yesterday it stopped working, like it should. The first thing I suspected was the ram, I swapped a lot of them (have 2-3 ram modules), and noting came out of it. It is difficult to explain exactly whats going on but I'll try.

When I press the power button, sometimes the bios will appear and try to boot to windows, sometimes it won't even come to the bios screen. When it powers up, the keyboard doesn't work, but 1 in 5 times it starts working again. When in bios (was able to get before the whole situation worsened), it said that the system memory is 633KB (while it should be 1,5 Gb), but when I managed to boot to vista, vista sees 1,5 Gb of ram. It was working for a minute or two, and the screen went either blank, or vertical lines appeared over it, but anyway, it froze still. I had a friend come over (2 heads better than one), and we both agreed after 5 hours that this is first time we ever saw sth like this. The behaviour is random, so you can't exactly pinpoint the source of problems. The same is if it is on ac or battery.

The hdd is ok, works in the external case pefectly. The ram should also be ok, all my ram modules that is. The vga chip is fine, or I wouldn't get a picture on the screen. The current thing that really annoys me that the keyboard & touchpad refuse to work. If they would work, I could again access the bios or try to log into vista (which is password protected).

My temporary conclusion would be serious hardware faulire on the mbo. I don't have the warranty anymore, and I don't feel like spending hundreds of $$$ for a replacement mbo, since I intened to sell it next week.

Does anyone have any idea what could be done still? The only thing I didn't do yet is take it completely apart, and reassemble it, rechecking connectors and that see if it will work. But as of now, I'm not sure it would do any good.

Thanks in advance

    Network Aadpters wouldn't work and I tried to install the required Driver through the ACER CD-Rom. As per the instructions I installed the ATI chipset and restarted the system but nothing showed up on the screen. I can hear the working sound of the laptop but the screen was blank. I tried turning off and on several times, still nothing showed up on the screen. Its been almost 2 years since I had any issues with my system and I am afraid if this could be fixed or not. Is there a solution for this problem. Please respond to

Cpu boots up and shuts off immediately before bios screen with charger attached

I suspect that in the abscence of any 0x00000FF type messages that would indicate why it is shutting down, that the problem lies in hardware failure. Other options are to try removing one stick of ram at a time and if possible replacing each to see if that solves the problem. I rather suspect that if this does not cure the problem, the charger is either incompatible with the laptop and / or damage has been done to the charging and power board.

No light, no up, nothings. power nothing please i need help. battery 100%

So the first thing to do is to plug it in so you can eliminate the battery as a potential problem, but if that does nothing, things are not so good.

If the laptop makes no sound at all, there are really only two pieces you can fix or replace, the HD and the RAM. The Ram is the easiest and will cost you about $20.

The manual to replace the ram is here:

The ram itself is here:

It is possible it is the hard drive which you can replace for about $40, but at that point, you may as well buy a new computer, because usually it is only your data you care about on a computer over 3 years old. might also try unscrewing the case. It is possible, but unlikely, you have a simple wire break in the power button or a weak contact in that switch. It is unlikely, but possible.

Good luck.

Standard RAM Failure after extended RAM replacement

Sometimes only certain types of RAM cards work with a computer. Check the old card to see what type it is. (Look for the letters "CMOS" or "EDO".) Make sure the new card is the same type as the old one. If not, put the old one back in and find the proper type of card.

Lappy is dead mon.

question: have you replaced the RAM by yourself??? do you get the problem before or after the replacement?

if you get the problem after replacement your RAM probably have static groundings... it was get from not demagnitizing your hands and tools before installing a RAM... if you still got the old RAM... clean the contact points and the RAM socket first and test the old RAM to your unit... if you stop having problems just return your 2gb RAM and ask for a replacement...
