My laptop is an Acer Extensa 5630Z that currently has 3GB of RAM. That page says I can only uprade to 4GB, but I wonder if that was just a hypothetical maximum, perhaps based on the largest RAM modules available when I bought my laptop. My question is if I could install, say, two of these 4GB sticks for a total of 8GB. My laptop is 64-bit capable, and that RAM is the proper type, so I don't see why there would be an arbitrary limit of 4GB (assuming I install Windows 7 64-bit).
I first tried to ask Acer over a chat if this would be possible, but let's just say I don't have much confidence in the support person's knowledge (he indicated 4GB is the max). Here is the shortened conversation for your review and amusement:
Me: I was considering buying some RAM for my Acer Extensa 5630Z. I was curious if there were any limitations of the size I could install. For example, could I get 2 PC-5300 DIMMs that are each 4GB (for a total of 8GB)?
Me: Just as an example, I found some RAM on NewEgg with the description "G.SKILL 4GB 200-Pin DDR2 SO-DIMM DDR2 667 (PC2 5300) Laptop Memory". I was thinking of buying 2 of those.
Him: You can upgrade up to maximum of 4 GB.
Him: Up to 2 GB of DDR2 667 MHz memory, upgradable to 4 GB using two soDIMM modules.
Me: Is that a limitation of the other hardware in the laptop, or was that just the largest amount of memory that was tested, or is that a software limitation?
Him: It will tested with maximum memory, and the system performance will affect, if you exceed the maximum memory.
Him: You can upgrade up to 4 GB RAM.
Me: OK, I just want to be sure there's no chance I could upgrade to 6GB or 8GB. I thought perhaps this type of RAM may not have been available when my laptop was made. Do you know that level of detail?
Him: I am sure, your system will compatible up to 4 GB up gradation only.
Have any idea of whether or not I should be able to do more than a "4 GB up gradation"?

Good news and bad news. According to this, the chipset supports 8GB. However, it also says "256-Mb, 512-Mb, 1-Gb, and 2-Gb memory technologies supported". So if the motherboard had 4 RAM slots, maybe it would allow for 8GB, but since there are only 2 slots, maybe it only allows for 4GB. Though, again, I run into the possibility that the largest RAM of this type may have been 2GB when this document was created.
Grrrrr.

Anyone know how to properly declutter a window 7 laptop. Ive done the Disk Cleanup (inclduing former restore points), defragged and run Piriform CCleaner.
I've found one directory online that got a few meg, but all I can free up is 12.5 G on an 80G disk.
Now I do have the RC for Visual Studio 2012 installed along side VS2008, but that would account for no more than 10G. One or other may have to go but I would prefer to retain 08 until 12 settles in. If pushed 12 gets it!
Looking over the drive using Winzip Utilities, the real perpetrators are thousands of small files that appear to be related to various automatic updates. I tried removing some of them but that caused chaos. The machine is over 4 years old, and was upgraded from Vista to 7 about 15 months ago.

I find it slows to a total stop when I dont power it on...

you can use tools like WinDirStats to find where the bulk of you storage is being used. That is always a good starting point. I would also recommend checking to see what processes are running and what programs are installed. Then ask yourself if you still use the programs and if not, remove them. Maybe more your documents and music and such to an external drive.
I would love to change the world, but they won't give me the sourcecode....

Install programs reduced to essentials (except the second Visual Studio!), All major documents moved off. I dont do movies / music etc on it.
Performance is actually not all that bad - its just that I am running out of room. I am considering cloning it to a bigger drive.
WinDirStats has helped my gain a further 4GB. When I have the MySQL wobble corrected, I should be able to increase that by perhaps another 1, giving me 17.
The real solution is to clone to a bigger disk - or buy a new laptop!

Anyone ever faced something like this? how to kill this shortcut generation?! 
[InternetShortcut]
IconFile=C:\Program Files\Internet Explorer\iexplore.exe
URL=https:
HotKey=0
IconIndex=0
IDList=
[{000214A0-0000-0000-C000-000000000046}]{Prop3=19,11

What do you mean "kill"? This is just a shortcut to a website, if you don't want to keep it then delete it from your PC.
|
|
|
|
|
It gets auto generated after some time, even if deleted.
|
|
|
|
|
Then you need to investigate whether you have some virus on your system, or some process that is recreating it and why.

Sysinternals has good tools that can help you track down such things.

Hello all. We developed an app that interacts with Facebook, by posting data to a specific account. This is done by establishing an HTTP request. In my server, this works perfectly. However, when I go to out customer's, it simply won't work.
I know that this guys have very tight security measures. One of those consist on blocking anything to do with Facebook. Now, we requested that for that server and a specific account to be free of such policies. They did so, and when opening the IE, they can connect to Facebook's main page. However, our program still throws a 400 Bad Request.
So I'm wondering if there is anything else blocking such connections. To that end, I downloaded Microsoft Network Monitor 3 and SysInternals TCPView. However, neither shred a light on the situation, other than showing which connections are made.
Thus my question: is there any tool out there that can be used to trace an HTTP connection and then detect where it is being blocked either by a policy or by a firewall? Or a clue on to what could be happening?
Thank you so much in advance!
Best regards.

Wireshark[^] will show you what's happening "on the wire". If it's local policy, you won't see anything. If it's a firewall, you'll see the 400 coming back. A clue to where it came from would be in the response time - the faster the response, the closer the rejection.

Previously I thought that the difference between pressing the [Del] key alone and the combination [Shift][Del] is that the former one puts the file to the recycle bin, and that's all of the differences.
But no, there is more: I changed the access rights to a file programmatically such that only SYSTEM can access it (OK, there is an inconsistency left: I am still the owner of that file). When I look at its properties, only SYSTEM is shown on the Security tab. When I press the [Enter] key, Notepad is started and tries to open the file, and shows an Access Denied message. When I press [Del], the Access Denied message is shown after a few seconds. But when I press [Shift][Del], the file gets deleted immediately. Happens both in Windows XP and Windows 7.
How can that be explained?

It's caused by the flunge panel cross dock inhibitor releasing locks on the bit-bat meta-glup of the file.

Ok, maybe some cleverer people than myself can help with this one. We have a business-critical application which runs with a MSSQL backend and generates a lot of documents (letters, etc., in Word and PDF format). At present the documents are just stored in a share on the same server as the database, with the filenames stored in a table and the documents called directly from the application on client computers when requested (I didn't design this, by the way!).
A little while ago, due to storage space issues on the server, I decided to move the documents off the server and onto a dedicated NAS (Netgear ReadyNAS 2100) with lots of capacity rather than just beef up the server's disk space. My reasoning was that the network load would be spread between the server and the NAS, instead of the server's NIC handling both database and document traffic. In practice, the performance of opening documents actually decreased dramatically for those departments which I migrated to the NAS, to the point where I halted the migration. Sometimes documents on the NAS open perfectly quickly, and a user will have no speed issues for several minutes or hours. Then, suddenly, one file will take literally a minute or more to open. These are only small Word documents and I'm only talking about a few dozen users who have been migrated.
ANYWAY, what I'm getting to is that it's time to replace all of this hardware anyway. I'm about to purchase a very powerful, fast server to replace the DB server. Reviews suggest that its I/O performance is exceptional. But I was also going to purchase a new, high-performance NAS and stick with the topology I've already described. My theory is that the speed issues are being caused by some deep-level communication problem between the Netgear ReadyNAS and the clients, which neither they nor I have been able to get to the bottom of. It still seems like sound reasoning to me that separating database and documents will result in a spread network load and increased performance. Am I wrong?
I don't know the technicalities involved in opening a document in a network share. Is it perhaps the case that the process of establishing a connection to the share and opening a file, at least the first time in a session, is much slower than opening the same file stored on the database server, to which a 'connection' is already established due to the user having been using the database?
Any discussion or advice on this topic would be greatly appreciated. If stuffing the database server full of disks and keeping the files on there is going to be the fastest solution, I'll save a whole lot of money!
Sorry for the wall of text - thanks!

I'd say there was soemthing wrong with your existing NAS. A firmware update might fix it, if there is one.
But, unless the server is being pounded constantly with tons of disk and network I/O, you're really not going to see any kind of performance benefit by going to an external NAS.

Hi,
i am going to use Wayne nucleus point of sale machine and i am developing my own back office system to manage data from this POS. is there any documentation on how do i configure my back office system with Wayne nucleus point of sale or it will be more convenient if someone can give me a link to Wayne nucleus technical support team via any email address or phone number.
thnx.
