My HP dv6 1030us laptop becomes slow when removed from AC power

Hi,
My HP DV6 laptop has windows 7 operating system and it behaves pretty weirdly .
It becomes really slow when removed from AC Power and have to restart my system to bring it to normal speed don't know why its behaving like that and help to resolve the problem would be greatly appreciated and also my system gets overheated a lot and I have to use a cooling pad always to keep it cool and running properly along with AC power
I would greatly appreciate any advice in resolving these issues.
Thanks in advance.

for how long have you had this laptop... If you had it for longer than a year you may be dealing with a dust bunny (acumulation of dust in the vent that's right beside the fan). Normally when that vent is clogged you get the type of overhetaing you may be experiencing, so i recomend you to open it up and give it a nice clean as soon as you can. As for your computer slowing down without the ac adapter.
Do you know under what power option are you running ur computer?

PL/SQL procedure is 10x slower when running from weblogic

Hi everyone,
we've developed a PL/SQL procedure performing reporting - the original solution was written in Java but due to performance problems we've decided to switch this particular piece to PL/SQL. Everything works fine as long as we execute the procedure from SQL Developer - the batch processing 20000 items finishes in about 80 seconds, which is a serious improvement compared to the previous solution.
But once we call the very same procedure (on exactly the same data) from weblogic, the performance seriously drops - instead of 80 seconds it suddenly runs for about 23 minutes, which is 10x slower. And we don't know why this happens :-(
We've profiled the procedure (in both environments) using DBMS_PROFILER, and we've found that if the procedure is executed from Weblogic, one of the SQL statements runs noticeably slower and consumes about 800 seconds (90% of the total run time) instead of 0.9 second (2% of the total run time), but we're not sure why - in both cases this query is executed 32742-times, giving 24ms vs. 0.03ms in average.
The SQL is
SELECT personId INTO v_personId FROM (
        SELECT personId FROM PersonRelations
        WHERE extPersonId LIKE v_person_prefix || '%'
) WHERE rownum = 1;Basically it returns an ID of the person according to some external ID (or the prefix of the ID). I do understand why this query might be a performance problem (LIKE operator etc.), but I don't understand why this runs quite fast when executed from SQL Developer and 10x slower when executed from Weblogic (exactly the same data, etc.).
Ve're using Oracle 10gR2 with Weblogic 10, running on a separate machine - there are no other intensive tasks, so there's nothing that could interfere with the oracle process. According to the 'top' command, the wait time is below 0.5%, so there should be no serious I/O problems. We've even checked JDBC connection pool settings in Weblogic, but I doubt this issue is related to JDBC (and everything looks fine anyway). The statistics are fresh and the results are quite consistent.

The setup is quite simple - the database is running on a dedicated database server (development only). Generally there are no 'intensive' tasks running on this machine, especially not when the procedure I'm talking about was executed. The application server (weblogic 10) is running on different machine so it does not interfere with the database (in this case it was my own workstation).
No, the procedure is not called 20000x - we have a table with batch of records we need to process, with a given flag (say processed=0). The procedure reads them using a cursor and processes the records one-by-one. By 'processing' I mean computing some sums, updating other table, etc. and finally switching the record to processed=1. I.e. the procedure looks like this:
CREATE PROCEDURE process_records IS
    v_record records_to_process%ROWTYPE;
BEGIN
     OPEN records_to_process;
     LOOP
          FETCH records_to_process INTO v_record;
          EXIT WHEN records_to_process%NOTFOUND;
          -- process the record (update table A, insert a record into B, delete from C, query table D ....)
          -- and finally mark the row as 'processed=1'
     END LOOP;
     CLOSE records_to_process;
END process_records;The procedure is actually part of a package and the cursor 'records_to_process' is defined in the body. One of the queries executed in the procedure is the SELECT mentioned above (the one that jumps from 2% to 90%).
So the only thing we actually do in Weblogic is
CallableStatement cstmt = connection.prepareCall("{call ProcessPkg.process_records}");
cstmt.execute();and that's it - there is only one call to the JDBC, so the network overhead shouldn't be a problem.
There are 20000 rows we use for testing - we just update them to 'processed=0' (and clear some of the other tables). So actually each run uses exactly the same data, same code paths and produces the very same results. Yet when executed from SQL developer it takes 80 seconds and when executed from Weblogic it takes 800 seconds :-(
The only difference I've just noticed is that when using SQL Developer, we're using PL/SQL notation, i.e. "BEGIN ProcessPkg.process_records; END;" instead of "{call }" but I guess that's irrelevant. And yet another difference - weblogic uses JDBC from 10gR2, while the SQL Developer is bundled with JDBC from 11g.

My daughter's older Ipod Touch is having a problem with images becoming pixilated when taken from an e-mail and placed into her camera roll. ( She wants to put on Instagram ) Any help?

My daughter's older Ipod Touch is having a problem with images becoming pixilated when taken from an e-mail and placed into her camera roll. ( She wants to put on Instagram ) Any help?

I think that may be a consequence of the email provider she is using. Some services (AOL is one example) inspect and modify email attachments, particularly photos, resulting in reduced resolution compared to the email that was sent.
The iPod does not do this. The resolution of the picture in the email she receives will be identical to what is imported.

Peep sounds when working from battery power

Hello
I bought a new HP DV6-1340 laptop
I hear some strange peep sound from the notebook hardware when its working from battery power.
When working from outlet power there is no peep sound from the hardware.
Maybe its because the battery is new or something there wrong ?
Thanks in advance for help

I solved it my self. It was OK (no buzz and fuzz) when it was plugged in (when the electicity line was down once and I was running on the UPS battery).....

Resources automatically deactivating when removed from Active Directory

This is a simplified version of my previous question:
What causes some resources to successfully deactivate when removed from AD, while other Project Server 2010 accounts have to be made inactive manually?
Also, if a resource is made inactive or deleted in Project Server, is it expected that their SharePoint account will be completely deleted?
Thanks!

When you remove the user from AD group, that account will become inactive in the next AD synchronization in Project Server. When the account is inactive, it will be removed from the PWA as well as all the workspaces.
In 2007, if you make the user inactive, it will deactivate project server access, but the user can access the project workspaces
In 2010 onwards, When the account is inactive, it will be removed from the PWA and workspaces.
Cheers. Happy troubleshooting !!! Sriram E - MSFT Enterprise Project Management

Delete emails from server when removed from phone inbox

I want my server (Verizon Yahoo) to trash and delete messages when I trash or delete them on my 5s. I have gone into my Verizon account on the phone, made sure Trash was selected rather than Archive, selected "Delete from server..."when removed from inbox"", restarted, etc. Everything else works in the account, and when I delete on the server, it is deleted on the phone. I want emails to delete from the server when I remove them from the phone's inbox. Supposed to happen, but doesn't.

Thanks for the reply. I wasn't very clear, I guess. What I want to do is Trash or Trash>Delete emails on my iPhone 5s and have them go away from the inbox on my Verizon/Yahoo server. That does not happen now, even though I have set the setting on my phone to do so. All the stuff in my inbox on the server reappears the next time my phone inquires, including the emails I've sent to Trash (on the phone) and those I've Trash>Deleted there. Not too worried about permanent, real, NSA-type deletion, because that just isn't going to happen - I am worried about the poor agent at NSA who has to read my boring, mundane emails, though. I just don't want to see stuff I've Deleted from my phone's inbox come back to the inbox. Zombiemail!

Things to consider when removing from AD domain a SQL Server 2008 which includes Reporting Services

Do any one have a link to a list of things to consider when removing from AD domain a SQL Server 2008 which includes Reporting Services, Analysis Services and Integration Services?
I am taking from an Active Directory domain several servers with SQL 2008 and Reporting Services, Analysis Services and Integration Services. The server will stay on its own without association to any domain, the server will keep its IP address and
the server will not change names.
I have done some research and I got the basic steps including, removing the user accounts from the domain, changing the services accounts, changing jobs and databases from being owned by users from the domain. But...
Are there other things in Reporting Services, Analysis Services and Integration Services internal databases that have an association with the domain AND that will fail after no longer being in the domain?
I've heard of Reporting Services subscriptions failing when the domain user account is no longer there...Are there any other got ya's that any one has encountered?
Please advice.
Note: I am posting in this forum basically because of what I heard on Reporting Services, but it may be a better idea to post into a more broad forum such as SQL Server Migration section.
Thanks beforehand

My ipad2 crashes when it is removed from the power supply. It can't be reset?

My ipad2 crashes when it is removed from the power supply. It can't be reset? Doesn't respond when plugged into my pc?

Hrm... that may be true and this may be a function of the phone email client that Apple just doesn't do.
No, I can easily MANUALLY delete the messages. I would prefer if I didn't have to do it twice, tho. Once on the mail server and once on the phone.
What I think the phone needs to do is, when it checks the POP, anything NOT there should be removed locally. I think you are correct on POP; the phone will poll the mx (mail exchanger) and the mx will pass off the messages to the phone. The phone then keeps ALL of that unitl you manually delete it.
If, say, I remove a message from the mx, I would like the phone, when next polls, to see that that particular message isn't on the server anymore and remove it locally.
Perhaps it's just me but if I delete the message on the mx itself, via my ISP's webmail interface, I really don't want to have to remove it again from my phone.
thxs!

Game performance becomes slow when unplugged

i have an hp dv5 1006 ax
with ati mobility radeon hd 3400
my games run smooth when plugged in but once unplugged it becomes slow and jerky
i tried setting the power options . it didnt help
any alternatives.. pls help

this is caused from your power settings utilizing your switchable graphics. go in your power settings and you can set it to not do that but then your battery will die faster.

HT1338 network become slow when using bluetooth.

I am using macbook pro retina display, my issue is, every time I turn my bluetooth on, the network become slow. anyone facing a same problem?

A lot of people were experiencing the same thing and reported it on the MacBook Pro forum. But that was when the rMBP first came out and I thought that the issue had been resolved with software/firmware(?) updates.
Are you running the very latest build of 10.8.2? With the supplemental updates as well?

Why number becomes slow when after formatting function is used?

When changing something at Numbers (table, font, colors, etc), it becomes slower. I don't understant why, as the PC is brand new...

Hi Nano,
How large is the table that you are formatting? Is there a way to separate your results (with formatting) in a small table *away* from your main data table?
Regards,
Ian.

Vmware Horizon 3.3.0 - slow when launched from a VM (WS2008 R2) - any solutions ?

Hi guys,
We have a VMware Horizon setup that works quite well when accessed from our laptops.
However, for a number of reasons we also need this environment accessed from a Windows Server 2008 R2 machine that resides as a VM on a hypervisor.
But the problem is it is very very slow when launched like this (you can feel the mouse cursor lagging or whenever you open a window on the published Vmware View machine). I will point out that the connection to the client VM (WS2008R2) is done through RDP.
The questions I have since I've not been able to find out so far are:
1) Is WS2008R2 x86-64 supported as a client ? Does installation of a VMware Horizon Client on it differ in any way than on a Windows 7 machine ?
2) Is the fact that it is virtualized the root cause of the slowness ? If yes, why is that and can I do something to fix it ?
Thank you very much , I really appreciate your help.
Jay.

Ok, solved it myself
It seems in the "Control Panel > Mouse Options > Pointers > Scheme" the "Windows Aero - System Scheme" was selected. The second I set that to None, the mouse cursor started behaving and it's moving normally.

Blackberry Hub slow when switching from any account to an Exchange Activesync account

I'm experiencing a very slow hub when switching from any account (facebook, LinkedIn, Whatsapp, Gmail, etc...) TO my work email using Exchange Activesync. When switching back from Exchange Activesync TO any other account the issue is noy there. It basically takes a couple of minutes to enter the Exchange Activesync acocunt, and looking at the Device Monitor, CPU section, seems like the Hub process is constantly at 50% CPU usage during this time. This is really causing me lots of issues, as of course I switch between accounts quite frequently. Any suggestions are welcome. Thanks for the support!

I'm having the same issue. What can be causing it.
It was fine using a Z30 until 10.3.1.1865 was recently updated.
Switching between all other accounts is fine just when going to my exchange account (or the main hub view)

Forms Opening is Very slow when opened from Client PC's.

All,
We are running forms application in 10.1.2.0 application server. We have a peculiar issue of slowness while opening forms from client PC's and not while opening from application server itself.
1) When opening the form from a Windows 7 PC it takes around 25 seconds
2) When opening the form from a Windows XP PC it takes around 15 seconds
3) When opening the form from the application server itself it took less than 3 seconds .
In essence all forms when opened from application server are opening very fast and when opened from client PC's it takes undue time. What might be the reason for the same, can anyone help us and we are pondering over this issue for some time. What are the files of interest to be visited for these kind of issues. We enabled tracing level 5 in JRE and could not find any thing fishy over it.
Request application server and forms experts to participate and help us to resolve.
Thanks in advance.

Even if it's a generic issue you need to break it down in smaller parts to actually get a clue what's causing your problem. By now there is nothing we can rule out as the only thing we know is that it's slow on the client PC's.
Building a small dummy form as suggested by Andreas is a good starting point. If the performance is also bad for a small form with one block you can rule out that it has anything to do with forms and it's caused by e.g. your network. If the small form performs well rebuild one of your forms step by step and do tests for each step. By that you should find what's causing troubles.
What you can also take a look at are network roundtrips: You have to set the console window of your forms, and enable networkstats in your formsweb.cfg
networkStats=yesA typical cause for (unnecessary) roundtrips are e.g. calls to the synchronize built in or timers. If you are using Javabeans you should also take a look at them. If you are looking at your network traffic wireshark is your friend ;).
