How does battery charge work ThinkPad T430s

I recently bought a Lenovo ThinkPad T430s 2356-LRG and was wondering how the charge technology worked. I have searched around and looked in the manual but I couldn't find a good answer.
My questions is that I use the notebook alot on AC power. And often for extended periods of mid to heavy load. I run Linux and have setup ChargeThreshold. It stops charge at 95% and begins again at 45%.
But when I keep the AC power on, and if the battery has 80% it does not move up or down as expected. Because it must drop lower than 45%.
Will the power then go straight to the machine and bypass the battery? Because the Battery-LED on the back is turned off. Or will it go via the battery and produce charge cycles on the battery?
So let's say the battery is bypassed will it then be fine to keep it on AC and active for a period of many days with heavy load but monitor the temp of the battery. I know heat kills it.
I could also buy an 95W power adapter and remove the battery completely from the machine when I have it at my desk for an extended period of time.
Solved!

Hey there MikalD and welcome to the forums!
What you are experiencing is as per normal. These charge thresholds are determined in your power manager, there is a nifty Knowledgebase Article about this.
First, open up the ThinkVantage Power Manager. Click on the battery tab, and then Battery Maintenance. This will open a window where you will be able to change and set your charging thresholds to your desired preferences.
Additionally, here are links that can give some insight and advice of how to increase the longevity of battery life.

To add to sig's reply, "calibrating" does not calibrate Lithiu-Ion batteries, it calibrates the charge reporting circuitry. If you look at the effect of deep discharging Lithium-Ion batteries in the data from the independent test group, Battery University, you will see that doing so shortens the life of the battery significantly. It looks like an optimum balance between use and life is at a discharge level of 50%.

Will iPhone battery charger work with my iPad 2 ?

Will iPhone battery charger work with my iPad 2 ?

It does work but it's not recommended:
iPhone charger is 5W
iPad needs 10W
So, yes you can charge an iPad but the iPhone charger will get spoiled and the charging will be very slow.
Hope this helps,

How does TimeOut(Sec) works/ behave in FTP Adapter?

Hi ,
How does TimeOut(Sec) works/ behave in FTP Adapter?
Lets Say : If I mention 300 Secs in this . How Should it behave ??
if a file processing in adapter is taking more then 300 sec , will it also be terminated ??? what error response i will get in such case.
Regards
Prabhat Sharma.

Hi,
if there's a network error the channel may hang (for a very long time)
if you specify 300 secs after that time the channel will reset the connection and you can start pooling again

How does SAPscript 'WRITE_FORM' works ?

Hi
I have a Z program working fine, it is a SAPM07DR copy and i aggregated some fields to WASCHEIN form.
But i see when the program (standard or copy) calls the write form, the field values in program have other values (just the previous values) than the values wich appears in the printed form.
For example:
WASCHEIN KOPF Window has the WERKS value:
 Plant: &*T001W-WERKS&
But when the write form is called
 CALL FUNCTION 'WRITE_FORM'
 EXPORTING ELEMENT = 'KOPF'
 WINDOW = 'KOPF'.
In the program the *T001W-WERKS field has a different value that the value wich appears in the spool, debugging i see that the field has the prevoius value in the program:
Program
*T001W-WERKS
(when Write Form).............Spool
 ' '...................................Plant: 0900
 '0900'.............................Plant: 0901
I had to do the same logic in my new aggregated fields, but i realy don't know why does the program works in this way.
Why the print program and sapscript function works in this way ?
How does WRITE-FORM works, that is where the function take from the values to print ?
Thanks
Frank

Hi Max
I hope the program works like you said, but it works:
old_werks = ' '
T001W-WERKS = '0900'.
*T001W-WERKS = T001W-WERKS .
*T001W-WERKS = old_werks. <-- ' '
CALL FUNCTION 'WRITE_FORM'
(form KOPF with *T001W-WERKS)
old_werks = '0900'
T001W-WERKS = '0901'.
*T001W-WERKS = T001W-WERKS .
*T001W-WERKS = old_werks. <-- '0900'
CALL FUNCTION 'WRITE_FORM'
(form with *T001W-WERKS)
But the FM prints 0900 and after 0901, when the *T001W-WERKS values were ' ' and '0900' !!!
(and with the *T001W-NAME1 field occurs in the same way)
Why does the FM prints that values ??
Thanks
Frank

Will the Stitchway UltraPower 1900 mAh Backup Battery Charger work with the Apple iPhone 4S?

I see no reason why it shouldn't. At prices I've seen down to $4.39, I wouldn't hesitate to give it a try. That's cheaper than a sandwich!

How does Merged Dimensions Work in WebI created on SAP BI Queries

Hi,
I need to know how does Merge dimensions work in WebI when using SAP BI Query as source?
Below is my understanding when connection is defined for the universe on oracle database:
1) To get the data in merged dimensions, there must be physical join (Either Direct or vai some other tables) between different tables at backend level (This means there must be join between tables in Oracle database.)
2) we get the UNION of data when dimensions are merged at webI level.
I dont know how this works in SAP BI.
Since there is different data model defined for different BI Queries in SAP , and for each BI Query and there is seperate Universe, So how can you get correct data in WebI when there is no connections in DSO's used in different BI queries?
Can any one suggest me the way data apperas in merged dimensions for WebI created on SAP BI?

I assume we are only talking about merging dimensions in Web Intelligence here and not on the BW backend. this is a client side mere where you have 2 resultsets.
if you want to do this on the BI server side it would be a multi-provider combining different InfoProviders - or a InfoSet - depending on the join type you need. MultiProvider is a union, Infoset allows you to choose

Transfer Rules: How does the mapping work?

Transfer Rules: How does the mapping work?
Is there a document out there that explains the following or can someone help clarify it for me. I have some confusion on what is really going on.
When I create an InfoSource (IS_Test) as a Flexible update and then Assign DataSource (DS_Test) and I respond Yes, to the message DataSource assignment DS_Test to InfoSource IS_Test Save
a) Under Transfer_Structure/Transfer_Rules in the InfoSource
1) the Transfer Rules tab, what are the fields found in the right column (Assigned InfObjct-field)? And where do the fields you enter in the left column (Communication Str/Transfer rules) eventually go?
2) the DataSource /Trans. Structure tab, can I always assume that all the fields in the right column (DataSource) came from DS_Test? The left column (Transfer Structure), in my test was exactly the same as on the right. Where do these fields eventually go?
b) Under Communication_Struct., in the InfoSource
3. the right column (ISource Fileds) where from those InfoObjects. if I am now creating my InfoSource. Where did they come from?
4. The left column is Communication Structure, which at this point has no InfoObjects, if I move a couple of InfoObjects from the right to the left, where do these Objects in the left eventually go?
5. what is the relationship between the Communication Structure in 4 and 1? Or any relationship between a) and b) as a whole?
Thanks.

Hi Caud,
As Ashish pointed out, communication structure contains fields (infoobjects) that suppose to go to data targets. Which IO in CS to which IO in the data target will go (and what transformation of data may occur) is determined in URs of the data target.
The transfer structure is the structure in which the data is transported from the source system into BW:
http://help.sap.com/saphelp_bw33/helpdata/en/3f/0e503c3c0d563de10000000a114084/frameset.htm
In Transfer_Structure/Transfer_Rules in the IS, DataSource /Trans. Structure tab, right part shows fields in the Datasource, the left part fields in the transfer structure. There is also a transfer structure in R/3 for a given DS. Transfer structure in BW is created identical to the TS in R/3 during TRs activation.
During data load data are transferred 1:1 from TS in R/3 to TS in BW.
TS in BW corresponds to the PSA table structure.
How data from PSA are transferred to the CS is determined in TRs.
The 3rd column (Field) (Transfer Rules tab, right part (Assigned InfObjct-field)), contains field names of the DS (TS); and the 1st column shows IO in the CS to which the DS field will go. So, its a mapping DS filed -> CS field.
The left part (Communication str./Transfer rules) is always identical to the CS content. But the 4th column (Tp) shows possible data transformation during transfer from PSA to CS. If this column contains a yellow triangle then there is no transformation (Value of DS field will go to value of CS field). If there is a red cross, it means that no data for this CS field is supplied from a DS. You can click on this yellow triangle and choose: 1). Another field from a DS; 2). Constant; 3). ABAP routine; 4). Formula. So, here you can determine the data transformation. Moreover, there is a possibility to create a start routine (blank sheet icon at the top).
And finally, here are the answers on your questions:
Q:
a) Under Transfer_Structure/Transfer_Rules in the InfoSource
1) the Transfer Rules tab, what are the fields found in the right column (Assigned InfObjct-field)? And where do the fields you enter in the left column (Communication Str/Transfer rules) eventually go?
A: Right part shows a mapping between DS and CS fields. Left part shows CS fields and data transformation (TRs) during data transfer from TS (PSA) to the CS. These are fields in the CS that will go to data target and which are fed from a TS (DS).
Q: 2) the DataSource /Trans. Structure tab, can I always assume that all the fields in the right column (DataSource) came from DS_Test?
A: Yes, you are right.
Q: The left column (Transfer Structure), in my test was exactly the same as on the right. Where do these fields eventually go?
A: As I described, left and right parts are identical. These fields will go to CS.
Q: b) Under Communication_Struct., in the InfoSource
3. the right column (ISource Fileds) where from those InfoObjects. if I am now creating my InfoSource. Where did they come from?
A: these are fields from an IS template, the name of this template you can see above this right part. Actually, during IS (CS) creation you can choose different templates and choose fields from them transferring them into the left part.
Q: 4. The left column is Communication Structure, which at this point has no InfoObjects, if I move a couple of InfoObjects from the right to the left, where do these Objects in the left eventually go?
A: these are fields of CS (left part) and as I said before they will go to data target.
Q: 5. what is the relationship between the Communication Structure in 4 and 1? Or any relationship between a) and b) as a whole?
A: CS in 4 just shows IOs that will be transferred to data target. CS in 1 also shows how values for CS IOs are to be fed and transformed.
Best regards,
Eugene

KPI -How does the periodicity works in SM

Periodicity is @ Context level only? That means we have to define different contexts for weekly &monthly? That doesnu2019t fly good
How does the periodicity works in SM..data entry as well as frontend display?

Hi TR,
When looking at a scorecard, you should see the status for all objectives and KPIs during the same time period. If you look at Revenue KPIs for just one week and Cost KPIs for the whole month, how can you assess how you performed in that month?
This doesn't mean that the metrics in PAS cannot have different periodicities. They can! But when looking at data in the scorecard these periodicities will be converted to the scorecard periodicity. For example if you have monthly metrics and you are looking at scorecard data quarterly, the scorecard will show you the value for the 3 months of that quarter. Here, you should take care to define the proper time consolidation properties for the metric (it can be SUM, like in costs or revenue, AVERAGE, LAST, FIRST...).
Likewise, if you have quarterly metrics and you want to see scorecard data monthly, then PAS does a breakdown of the value per months.
Anyway, if you are looking to setup a weekly scorecard, that will likely include a different set of metrics that a monthly scorecard would. Weekly scorecards will problably include more operational metrics and will lack the strategic focus of scorecards with a broader time scope.
Regards!
Ricardo

How does SUM actually works

Hi,
I'm puzzled by how SUM actually works.
I've got a table with the following fields:
SET_OF_BOOKS_ID NOT NULL NUMBER(15)
SUMMARY_CODE_COMBINATION_ID NOT NULL NUMBER(15)
DETAIL_CODE_COMBINATION_ID NOT NULL NUMBER(15)
TEMPLATE_ID NOT NULL NUMBER(15)
LAST_UPDATED_BY NOT NULL NUMBER(15)
LAST_UPDATE_DATE NOT NULL DATE
ORDERING_VALUE NOT NULL VARCHAR2(25)
Using the below, I was able to get the total value of all the ordering value.
select sum(ordering_value) from gl_account_hierarchies where set_of_books_id = 1 and summary_code_combination_id = 1147;
I was happy that I could get the total value but am puzzled as ordering value is of data type VARCHAR2.
Is sum(ordering_value) a VARCHAR2 or a NUMBER then?
I did a simple test, inserting the following record:
insert into gl_account_hierarchies values(1,1024,1,2,3,'11-APR-2002','xyz');
After committing, I double check by using the following statement:
select * from gl_account_hierarchies where last_update_date = '11-APR-2002';
and was able to retrieve the newly inserted record.
But when I did another check with the following statement:
select * from gl_account_hierarchies where set_of_books_id = 1 and summary_code_combination_id = 1147;
I wasn't able to retrieve the newly inserted record.
Why is that so? How does SUM actually works? Is the output of SUM a VARCHAR2 or NUMBERIC value?
thanks in advance!!
Yu S.S

SUM() gives a number.
What you have come across is an implicit data conversion. Basically the SQL parser doesn't reject your query as being syntactically invalid just because you're attempting a mathematical function on a non-numeric column. Instead when you execute your query SQL substitutes this
select sum(to_number(ordering_value)) from gl_account_hierarchies where set_of_books_id = 1 and summary_code_combination_id = 1147;
If you want to check this create a view
create order_value as select sum(ordering_value) sum_val from gl_account_hierarchies ;
and then desc it.
Cheers, APC

How does request.setAttribute() works?

How does request.setAttribute() works?
 Does it append data to http header and forward? Does it set to a memory
 space like session.setAttribute() does?
 Thank you
 Jim


 Q. Does it append data to http header and forward?
 No.
 Q. Does it set to a memory space like session.setAttribute() does?
 Yes. So you can set attributes in request scope and use them in the servlets and
 JSPs in the servlet chain via request dispatcher and jsp:include/jsp:forward.

How do EDGE charges work/where do I look for itemized billing GoPhone Pic

How do EDGE charges work/where do I look for itemized billing. I have the GoPhone Pick Your Plan. The AT&T _phone call_ charges are clearly itemized on line at AT&T.
Can I view the charges for the Media Net Unlimited feature package? I have connected to WiFi at the local coffee shop. I have connected briefly to a local TV weather page while using EDGE. I fear the twenty or thirty dollar charges I have read about if I do any serious use of Safari while using EDGE.
I have explored this on the following:
http://www.lindenlan.net/2007/08/15/prepaid-vs-contract-att-gophone-or-nation-pl an/
and
http://www.tuaw.com/2007/09/24/prepaid-data-packages-and-the-iphone/
and both suggest I will be thoroughly reamed unless I am on a WiFi hot spot.
Every time I read the word "Unlimited" in my unlimited Media Net package there is the dreaded double asterisk "**" and the warning "additional per minute charges apply.
I don't see a charge for my maiden foray onto the internet using EDGE to view the weather page at KKTV so where is it. Surly I cannot use EDGE without charges on this turkey plan. Or can I ?

How exciting ! You have gone way beyond the call of duty for me. I appreciate it; thanks. I am so pleased with the iPhone but did not want to spend my life in coffee shops just to use it. Also I need the map function at work to help my customers and we have no WiFi there yet. But looks like I am ok at work on EDGE.
Every other day I was oscillating between being extremely pleased with my purchase and then chastising myself for spending all the money on the service that I was sure would be inadequate. I don't call much and considering how fast things are changing I don't want to be locked into a two year contract though I understand Apple is locked into five years exclusively with AT&T.
I hope good things come your way !

how does chat applet works? What specific technologies should i learn to make a chat messaging work?
thanks in advance for ur help...

Chat applets work on sockets. Normally there are two parts. One server and one or more clients. The clients connect to the server and any message sent by a client is then distributed by the server to all the other clients.
